RHIC science has entered an era where the goal is to make quantitative statements about the evolution and properties of the super-hadronic matter created in high-energy heavy-ion collisions. Given the heterogenous nature of the RHIC and LHC heavy-ion data sets, the significant uncertainties to the theoretical models, and the complex intertwined dependencies between model parameters and observables, stating conclusions with meaningful uncertainties represents a major challenge. I will present results from the MADAI collaboration, where we have constructed a statistical infrastructure for addressing exactly such problems and applied it to a subset of soft observables from 100A GeV + 100A GeV Au + Au collisions. The results from this pilot project are promising and the techniques should be extendable to larger data sets and to more flexible models with greater numbers of parameters.

Plasma-Material Interface (PMI) mixes materials of the two worlds, creating a dynamical surface which is one of the most challenging areas of multidisciplinary science, with many fundamental processes and synergies. We present the experimentally validated atomistic theory and computation for studying the dynamics of the creation and evolution of the PMI under irradiation by atoms and molecules at carbon, lithiated carbon and tungsten, as well as the emerging elastic and inelastic processes, in particular retention and sputtering chemistry. Recent work with lithium coatings deposited on a variety of metallic and graphitic surfaces, in a number of tokamak fusion machines around the world, has provided evidence of the sensitive dependence plasma behavior has on these ultra-thin deposited films. Our computer simulations, done in collaboration with Japanese and French scientists, and validated by in-situ experiments at Purdue University and at NSTX of PPPL have elucidated roles of lithium in carbon walls to the recycling of the plasma hydrogen. We performed quantum-classical atomistic calculations on many thousands of random trajectories to clarify the interplay of lithium and oxygen in amorphous carbon. We show that the presence of oxygen in the surface plays the key role in the increased uptake chemistry and suppression of erosion, while lithium has a decisive role in achieving high concentrations of oxygen in the upper layers of the surface upon bombardment by deuterium. D atoms preferentially bind with O and C-O when there is a comparable amount of oxygen to Li at surface. This finding explains a number of previously puzzling laboratory and reactor-based experimental results obtained over the last decade, having ramifications that go well beyond fusion.

The talk will review work at the division of quantum device physics at Chalmers. Quantum, limited dimensional devices can be used to study fundamental physical effect. At Chalmers, microwave pumped SQUID (Josephson inductance) terminated transmission lines have been used to study dynamical Casimir effects, i.e., vacuum fluctuations parametrically amplified to photons at half the pumping frequency. An imaginary component to the energy gap at node directions have been detected in YBCO by a single electron transistor. YBCO nanostructures can also be used to fabricate low noise SQUIDs. One use may be to study brain rhythms. Quantum Hall resistance normals have been realized in SiC based graphene. Their resolution is of the order of one part in ten-to-the-ten, and they promise to be the resistance standards in the future.

After reviewing the basic properties of jets produced in elementary collisions, and how these can be understood from quantum chromodynamics (QCD), I shall show how the QCD cascade is modified by the presence of a quark-gluon plasma. Coherence effects that determine the most salient features of the QCD cascade in vacuum are suppressed, and the in-medium cascade exhibit turbulent behavior. Interestingly, the same self-similar behavior that characterizes this turbulent behavior shows up in the late stage of the "bottom-up" scenario for quark-gluon plasma thermalization.

Inelastic scattering measurements performed with resonance-tuned X-rays can provide a unique window into electron behavior at a femtosecond time scale and atomic length scale. Experiments of this type have a broad range of applications, granting key insight into the energetics of complex chemical environments (e.g. charging battery electrodes) and correlated electron systems (e.g. high temperature superconductors). I will discuss current efforts to turn the phase and energy profile of scattered light into a time-resolved picture of electron dynamics in quantum materials. The talk will review how many-body systems respond when impacted by resonant X-rays, and how scattered photons provide a fingerprint of important material properties such as atomic valence and spin states. Throughout the talk, I will touch on the long term trajectory of research, and ways in which the rapid ongoing development of spectrometers and X-ray light sources is opening exploration into new realms of fundamental physics.

"MaRIE stands for Matter-Radiation Interactions in Extremes. As ultimately envisioned, the MaRIE facility as a whole will be capable of applying several in situ diagnostics to observe transient phenomena at high resolution, in real time. These include both proton radiography from the existing LANSCE accelerator, and X-ray and electron radiography from the MaRIE 1.0 XFEL. MaRIE 1.0 will be the world's first very-hard (40 kV) x-ray free-electron laser. Designed to operate with a beam energy of 12 GeV, the MaRIE linac will require performance currently beyond state-of-the-art in most aspects of its design: beam source, linac structures, bunch compression, bunch train, and the diagnostics required to monitor all of the above. MaRIE presents challenges not only in terms of achieving the basic performance requirements, but also to the modeling and simulation tools we use to design such a machine. This talk will review the baseline MaRIE 1.0 requirements and present the current status of the baseline accelerator design. Approaches to addressing the design and modeling challenges will be presented, along with broader-ranging potential alternatives."

Panel Discussion with Christina Swinson of BWIS, Q & A, light breakfast served. Equal Pay Day The Annual Equal Pay Day Event is held to bring awareness statewide about the inequality in pay between men and women. Over fifty years ago the United States Congress passed the Equal Pay Act, yet women who work full time still earn just 77 cents for every dollar earned by a man. Every year EPW chapters plan an event that brings awareness to this inequality and participate in activities that make an impact on achieving change. Examples of Equal Pay Day and local projects.

Coffee and cookies at 10:45 am Center for Functional Nanomaterials Colloquium Series Professor Paul V. Braun Department of Materials Science and Engineering University of Illinois at Urbana-Champaign Soft Matter Enhanced Electrochemical Energy Storage and 3D Photonic Crystals Tuesday, April 8, 2014 11:00 a.m. Seminar Room, 2nd Fl. Over the past decade, the sophistication of self and directed-assembly approaches for functional composite structures has increased dramatically, however, application of such structures in real-world systems has remained largely elusive, in part because such structures almost always contain finite defect densities. The storing, generating and harvesting of photons and electrons presents a unique opportunity for self-assembled composite materials. These applications are not only generally much more defect tolerant than for example self-assembled computational electronics, but also for these areas to make a substantive impact on the world energy situation, they must be produced in exceptionally large volume. In my talk, I will attempt to capture the state-of-the-art in highly functional self-assembled three-dimensional composites for energy harvesting and storage illustrated with examples from both my research and other groups with a particular focus on high charge and discharge rate nanostructured electrochemical energy storage systems (batteries and supercapacitors), and photonic crystals which exhibit unprecedented control over the absorption and emission of light (lasers, LEDs, and solar cells).

We all know that High Energy Physics research in the U.S. is funded almost entirely by the federal government. Our field competes for federal dollars with colleagues as close as Nuclear Physics, and as far removed as the National Park Service or School Lunch Program. Just how does our budget get put together, and by whom? What do we do, specifically as a User community, to advocate for our research program to the people who make the funding decisions for our field? Do we have any real, positive effect? And finally, how are the answers to these questions impacted by the current P5 process?

Water oxidation to oxygen in nature's photosynthesis is the source of most of the energy we use today. It is also anticipated to be (and it has to be) the source of most of the energy we use in the future through artificial photosynthesis. For the latter, one of the main challenges is the development of efficient and robust water oxidation catalysts. In this presentation, water oxidation catalysis by ruthenium complexes with two types of tetradentate ligands (2,2'-bipyridine-6,6'-dicarboxylic acid,bda and 2,2'-bipyridine-6,6'-diphosphonic acid, bpa) will be discussed. These catalysts oxidize water through seven-coordinate intermediates but follow different mechanisms. Water oxidation catalysts of the type [Ru(bda)(L)2] (L is 4-picoline (pic), or isoquinoline (isq)), as well as their mechanism for water oxidation, have been reported by Sun and coworkers. Nevertheless, unlikely 20- and 19-electron intermediates were proposed in the catalytic cycle. Here we revisit the mechanism for water oxidation by these catalysts based on electrochemistry, X-ray crystallography and well established inorganic and organometallic chemistry principles. In addition, a comparison between the two types of complexes in solution and bound to metal-oxide electrodes will be made with respect to catalytic performance. This comparison sheds light on the mechanism by which these complexes oxidize water in a true solar cell device configuration.

"I will first analytically show a simple, yet subtle "invariance" of two-body decay kinematics for the case of a massless daughter and a mother particle which is unpolarized and has a generic boost distribution in the laboratory frame. Namely, the laboratory frame energy distribution of the massless decay product has a peak, whose location is identical to the (fixed) energy of that particle in the rest frame of the corresponding mother particle. As a proof of principle of the usefulness of this observation, I will then apply it for measuring the mass of the top quark at the LHC, using simulated data (including experimental effects). Finally, I will show how it can be used to measure all the superpartner masses in a cascade decay chain of the gluino."

Among the future hopes for high energy nuclear physics is the construction of an Electron-Ion Collider or EIC. BNL has developed detailed plans for the RHIC machine to evolve into the EIC (locally called eRHIC) by the addition of an electron ring. For the past several years, BNL has hosted an EIC R&D program targeted at addressing the technology needs for the EIC. I will report on the so-called "Tracking Consortium" work with particular emphasis on the compact RICH. The compact RICH uses CsI-coated Gas-Electron-Multipliers (GEMs) along with a specialized thin-coating mirror for good reflectivity into the deep UV. Results from test beam will be presented along with thoughts for further work.

Interfacial fluid mechanics, such as the dynamics of drops and bubbles, are important to problems in a variety of fields. For example, superhydrophobic surfaces can repel droplets, and bursting bubbles can disperse marine aerosols into the atmopshere. In this talk, I focus on two distinct phenomena: the reduction in contact time of a bouncing drop and the drainage of a viscous bubble prior to rupture. I will show both high-speed and time-lapse movies to highlight the phenomena, and I will discuss how experiments and mathematical modeling have given us insight into the underlying physics.

In all known types of high-Tc superconductors - cuprate, Fe-based, and heavy fermion compounds - superconductivity emerges from the suppression of long range antiferromagnetic order. However, while superconductivity emerges from a Mott insulating state in the cuprates, the parent compounds of the Fe-based superconductors are metallic. Could a higher Tc be realized in compounds similar to the Fe-based superconductors if we start with a more correlated parent compound? We have synthesized single crystals of LaMnPO, which is isostructural to LaFeAsO, by the ux growth method. We find LaMnPO is an antiferromagnetic insulator that orders at TN = 375 K with a moment μ= 3.3 μB as T right arrow 0. I will present a combination of inelastic neutron scattering and optical transmission measurements and to show that antiferromagnetic exchange plays only a small role in formation of the charge gap. Instead, DFT+DMFT electronic structure calculations find Hunds coupling, thought to be responsible for correlations in the Fe-based compounds, is crucial for the formation of a charge gap in LaMnPO. Having identified LaMnPO as a more correlated version of the Fe-based superconductors, I will present our pressure and doping studies of LaMnPO. We find pressure drives LaMnPO toward a metallic and paramagnetic phase, but do not observe superconductivity. Doping studies are successful in reducing the activation gap in LaMnPO but the charge gap remains nearly unchanged.

We propose to place a stack of ultra thin transmission dynodes on top of a pixel chip, in vacuum. A single electron arriving at the first dynode will cause an electron avalanche on the pixel input pad. Due to the small source capacitance, a gain of 30 k of the dynode stack is sufficient to create a digital signal. The rise time of this signal could be ~ 2 ps. This single-electron sensitive device has therefore an excellent time resolution, and, due to the granularity of the pixel chip, a good 2D position resolution. When capped with a classical window + photocathode, a new photomultiplier is created. This Timed Photon Counter 'Tipsy' is single soft photon sensitive, has 2D position resolution defined by the granularity of the pixel chip, and a potential time resolution of ~ 2 ps per photon. Thanks to the granularity of the pixel chip, a high rate of multiple photon events results in an acceptable pixel occupancy. When capped with an electron emission membrane 'e-brane', the electron detector turns into Trixy: a tracker for charged particles (MIPs). The essential property of this membrane is the emission, with a high probability, of at least one electron after the passage of a MIP, at the crossing point of the MIPs' track and the membrane. We report on the progress in the development of the transmission dynode, and on theoretical aspects and simulations associated with the emission of (secondary) electrons.

In this talk I will outline our groups efforts to generate and understand the high temperature superconducting proximity effect. Our focus is on interfaces between high Tc cuprates and topological insulators, in the hopes of observing and manipulating Majorana Fermions. I will also discuss the interest in these particles from both a fundamental and applied point of view. This has led us to develop the Mechanical Bonding processes that resulted in the first observation of high temperature superconductivity in Bi2Se3, Bi2Te3 and Graphite. I will also discuss recent efforts on the proximity effect in Bi2Te2Se where the fermi energy is in the gap. Interestingly in Bi2Te2Se/Bi2212 junctions we have observed a new zero bias conductance peak that does not couple to the orbital component, but only the spin.

Despite the complexities of the nucleonic interactions in atomic nuclei, nuclei display remarkably simple patterns, and regularities as a function of neutron and proton number. Many of these patterns are associated with the emergence of collective behavior. Such behavior is largely the result of a competition between pairing interactions between like nucleons and proton-neutron (p-n) interactions. The Colloquium will survey the empirical behavior of nuclei and present ways to experimentally extract the strength of p-n interactions. The pivotal role of the latter in determining the former will then be discussed in terms of the correlations of p-n interaction strengths with the onset of collectivity and a newly recognized parallelism in the filling of proton and neutron orbits.

Understanding extreme events, such as hurricanes or forest fires, is of paramount importance because of their adverse impacts on human beings. Such events often propagate in space and time. Predicting��"even a few days in advance��"what locations will get affected by the event tracks and/or at what seasonal intensity these events are anticipated at those regions could benefit our society in many ways. Arguably, simulations from first principles, where underlying physics-based models are described by a system of equations, provide least reliable predictions for variables characterizing the dynamics of these extreme events. Data-driven model building has been recently emerging as a complementary approach that could learn the relationships between historically observed or simulated multiple, spatio-temporal ancillary variables and the dynamic behavior of extreme events of interest. While promising, the methodology for predictive learning from such complex data is still in its infancy. I will present a suit of dynamic networks-based methodologies for in-advance prediction of the dynamic tracks of emerging extreme events, for quantifying seasonal hurricane activity in North America, and for assessing rainfall activity in the Western Africa. These methods offer a superior predictive skill compared to any other methodology currently available in literature. In addition, various strategies for dealing with large-scale graphs will be presented.

"In a muon accelerator complex, a target is bombarded by a multi-MW proton beam to produce pions. The pion beam is captured by a high field tapered solenoid and later decay into muons. The captured muon beam has a large 6D emittance which requires reduction in order to fit within the muon accelerator acceptance and provide the required luminosity during collision in the collider ring. An optimization study of the muon beam production and capture will be presented including the impact of the capture solenoid field on the transverse and longitudinal phase-space of the muon beam. Additionally a design study of the muon collider final ionization cooling channel utilizing high field solenoids will be discussed."

In the presentation, I will talk about the new approach to generate ultra-short x-ray pulses of the order of 100fs pulse length by electron beam slicing, and I will discuss our from start to end design of the electron beam slicing method in NSLS-II which includes the design of low energy bunch compressor, the design of the interaction of the linac bunch and the ring bunch and the separation design of the synchrotron radiation of the core and satellite."

We introduce a "renormalized entanglement entropy" which is intrinsically UV finite and is most sensitive to the degrees of freedom at the scale of the size R of the entangled region. We illustrated the power of this construction by showing that the qualitative behavior of the entanglement entropy for a non-Fermi liquid can be obtained by simple dimensional analysis. The functional dependence of the "renormalized entanglement entropy" on R can be interpreted as describing the renormalization group flow of the entanglement entropy with distance scale. The corresponding quantity for a spherical region in the vacuum, has some particularly interesting properties. For example in three (spacetime) dimensions, it is always monotonic along RG flows, and provides a measure of the number of degrees of freedom of a system at scale R.

I will show that the acoustic scaling patterns of anisotropic flow for different event shapes at a fixed collision centrality (shape-engineered events), provide robust constraints for the event-by-event fluctuations in the initial-state density distribution from ultrarelativistic heavy ion collisions. The empirical scaling parameters also provide a dual-path method for studying the temperature and baryon chemical potential (T, \mu_B) dependence of the specific shear viscosity (eta/s) of the quark-gluon plasma (QGP) produced in these collisions. An initial calibration of the scaling parameters via detailed viscous hydrodynamical model calculations, gives robust eta/s estimates for the plasma produced in Au+Au and Pb+Pb collisions at RHIC (Root_s =0.2 TeV) and the LHC (Root_s = 2.76 TeV) (respectively) which are insensitive to the initial-state geometry models considered.

Human epithelial cancers remain incurable, putting researchers on a constant quest to develop models and methods that will lead toward a deeper understanding of the disease. Bugallo, Electrical and Computer Engineering professor at Stony Brook University believes that it is possible to provide information on the evolution of cancer stem cells and tumors that are highly drug-resistant and do not respond to standard anti-cancer drugs through the development of models and methods that follow signal processing methods. These methods could provide fast, scalable, and expandable information filling in missing gaps, further enabling the fight against cancer

The measurement of the shape of the Z boson rapidity distribution for pp Z/�'*  e+e- + X events at a center-of-mass energy of 1.96 TeV is presented in this seminar. Data collected with the D0 detector during the whole RunII period of the Fermilab Tevatron pp collider are used. By using these data with an integrated luminosity of up to 9.86 fb-1, the uncertainties on the rapidity distribution in the forward region are significantly reduced compared with previous measurements. The measurement is made for events with electron-positron mass between 66 and 111 GeV. Predictions of Next-to-Leading-Order QCD theory with CTEQ and MSTW parton distribution functions are found to agree well with the data over the full rapidity range.

At the highest possible transverse momenta at the LHC, quarkonia production should be dominated by fragmentation. I review recent developments in the calculation of quarkonium fragmentation functions using Non-Relativistic QCD (NRQCD) and SCET, including both single and double parton fragmentation functions. I then describe the recently developed fragmenting jet functions, which are applicable for calculating the cross section for an identified hadron produced within a jet. For a jet containing a quarkonium, these functions are calculable in terms of NRQCD production matrix elements. We show that measurement of the momentum distribution of quarkonium within a jet provides a novel means of extracting these matrix elements, thereby providing an interesting new test of NRQCD.

The suppression of high transverse momentum charged particles is an important signature of the strongly interacting medium produced in central PbPb collisions. Both partonic energy loss and the initial state of the collision system may contribute to the nuclear modification factor. To further understand and distinguish these effects, the charged particle production in pPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair has been measured with the CMS detector. This measurement covers a broad transverse momentum range of 0.4 to 100 GeV/c, and several pseudorapidity ranges. The nuclear modification factor is determined at midrapidity by normalizing the measured pPb spectrum to an interpolated pp reference spectrum constructed from previous measurements, and is significantly enhanced for particles with a transverse momentum above 30 GeV/c. The asymmetry of the collision system provides an opportunity to study nuclear effects on the parton distribution function by considering the production of charged particles in different pseudorapdity ranges. To quantitatively measure these effects, the ratios of the charged particle yields between corresponding positive and negative pseudorapidity ranges have been determined. The evolution of these ratios with pseudorapidity will be discussed.

Modern capabilities in computations and simulations in multi-scale approaches allow us to address successfully many of the complex chemistry and physics fundamentals of sun-to-fuel and electricity-to-fuel energy conversions. In this presentation we will highlight recent studies dealing with photo-electrodes, proton membranes, and molecular electro-catalysis, relevant to new energy technologies. In the context of photo conversions, efficient e/h polaron transport in single and multiphase oxide electrodes (such as TiO2 or Fe2O3) is essential. We successfully characterized the single-phase e/h transport properties of these materials using density functional theory DFT combined with Marcus/Holstein theory. Challenges remain for multi-phase materials. Our calculations led us also to formulate a universal role of excess electrons on the surface chemistry of oxides. In the context of proton membranes for fuel cells, understanding the factors affecting proton transport and molecular selectivity in polymeric and ionic liquid membranes is critical to the design of efficient low cost stable membranes. Ab initio and classical molecular dynamics MD combined with percolation theory provided a means to characterize successfully pore structure and proton transport properties. Water percolation is a key to efficient proton transport. Most recently, our focus has been on molecular electro-catalysis. DFT-based quantum QM and mixed QM/MM approaches coupled with accelerated MD simulations for free energy calculation, and micro-kinetic modeling have been combined to predict accurately the catalytic performance of novel proton relay-based molecular catalysts for H2 oxidation and evolution. These efforts have reached what is perhaps an unprecedented level of success that put us within grasp of design by computer. These studies underscore the power of computations and the impact of high performance computing in characterizing the fundamental chemistry in such complex mole

"Acoustic scaling of anisotropic flow in shape-engineered events: implications for extraction of η/s(μB,T) of the QGP"

Thursday, April 24, 2014, 12:30 pm

I will show that the acoustic scaling patterns of anisotropic flow for different event shapes at a fixed collision centrality (shape-engineered events), provide robust constraints for the event-by-event fluctuations in the initial-state density distribution from ultrarelativistic heavy ion collisions. The empirical scaling parameters also provide a dual-path method for studying the temperature and baryon chemical potential (T, \mu_B) dependence of the specific shear viscosity (eta/s) of the quark-gluon plasma (QGP) produced in these collisions. An initial calibration of the scaling parameters via detailed viscous hydrodynamical model calculations, gives robust eta/s estimates for the plasma produced in Au+Au and Pb+Pb collisions at RHIC (Root_s =0.2 TeV) and the LHC (Root_s = 2.76 TeV) (respectively) which are insensitive to the initial-state geometry models considered.

"Exploring three-flavor neutrino oscillations with MINOS"

Presented by Joao Coelho, Tufts University

11 am, Small Seminar Room, Bldg. 510

Friday, May 2, 2014, 11:00 am

Hosted by: Elizabeth Worcester

Since the discovery of neutrino oscillations and through the combined efforts of many experiments we now know all of the neutrino mass splittings and mixing angles with reasonable precision. The remaining unknown quantity is perhaps the most relevant piece of the puzzle: the CP violating phase $\delta$. While a two-flavor approximation is usually applicable in measurements of mixing angles and mass splittings, CP violation is only present in a complete three-flavor description of neutrino oscillations. Additionally, two other discrete symmetries are broken by the inclusion of a third neutrino flavor: the mass ordering and the mixing angle octant. The determination of these extra discrete parameters is paramount to resolving degeneracies and enabling the precise measurement of $\delta$. In this seminar the latest oscillation results from the MINOS long-baseline neutrino experiment will be presented. The analysis performs a fit to three-flavor neutrino oscillations including the full data set of beam and atmospheric neutrinos and antineutrinos. It is the first combined analysis of $\nu_\mu$ disappearance and $nu_e$ appearance data by a long-baseline neutrino experiment.

"Core-collapse supernovae have challenged theorists and computational science for half a century. Such explosions are the source of many of the heavy elements in the Universe and the birthplace of neutron stars and stellar-mass black holes. However, determining the mechanism of explosion remains the key goal of theory. Though the synergistic operation of turbulence and neutrino heating seems implicated, and multi-dimensional simulations with some physical fidelity that have provided insight, we have yet to reproduce the phenomenon theoretically. In this talk, I will review the goals of supernova theory, the state of the field, and the contending explosion models. In the process, I will highlight the computational astrophysics that has been applied to date, and that may be necessary in the future to credibly unravel this mystery."

Presented by Herman B. White, Fermi National Accelerator Laboratory

3 pm, Large Seminar Room, Bldg. 510

Wednesday, May 7, 2014, 3:00 pm

Hosted by: Ketevi Assamagan

Many metrics are not universally accepted in quantifying the impact of scientific research in general. The problem is more acute in the case of discovery science, where the motivation for pursuing the research was not necessarily to address or solve a specific economic problem, and therefore not readily tied to a return on investment for example. The topic to be presented in this colloquium focuses on the economic impact of particle physics research, and in general the impact of discovery science. The information is derived from one of our study groups, completed in the summer of 2013 at the University of Minnesota for the strategic planning exercise of the particle physics community of the United States. Making the case for supporting this science for DOE Laboratories occasionally includes a response to questions about the benefits to society of this research, including the economic benefits. If it were possible to better understand the broader impacts of the direction of this research, then hopefully this would contribute to making a clearer case for pursuing this research among decision makers.

It has been known that magnetic fields enhance the chiral symmetry breaking (ChSB). According to studies of QED or models of the 4-fermi interactions, it was expected that the enhanced ChSB would resist the chiral restoration effects, increasing critical temperatures for the chiral restoration and deconfinement. Recent lattice calculations, however, showed the opposite behavior: the critical temperatures are reduced as a magnetic field increases. I will discuss how to resolve this apparent paradox, emphasizing which characteristic features of QCD make differences from other models.

"Materials in 2-dimension and beyond"

Presented by Philip Kim, Columbia University

3:30 pm, Large Seminar Room, Bldg. 510

Tuesday, May 13, 2014, 3:30 pm

The recent advent of atomically thin 2-dimensional materials such as graphene, hexa boronitride, layered transition metal chalcogenide and many strongly correlated materials, where weak van der Waals (vdW) force holds the layers together, has provide a new opportunity of studying novel quantum phenomena in low dimensional systems. The vdW layered materials consist of covalently bonded atomic layers entities that weakly interact with other constituents. With a strong built-in anisotropy in their components, vdW materials often show a quasi-low dimensionality leading to strongly correlated electron behaviors. These materials in 2-d limits also allow us to apply new experimental techniques such as electrolyte gating, scanning potentiometry, and electromechanical magnetometry. Moreover, combination of different layered constituents may produce heterogeneous and functional materials. In this talk, we will discuss to develop the method of transferring two-dimensional atomic layers of van der Waals solids to build functional heterostacks. Novel electron transport and optoelectronic phenomena can occur across these hetero-interfaces of atomicallycontrolled quantum heterostructures.

NSLS-II Seminar

"A metallic glass that grows from the melt like a crystal"

Presented by Gabrielle Long, ANL, United States Minor Outlying Islands

2 pm, Bldg. 743 Rm 177

Friday, May 30, 2014, 2:00 pm

Hosted by: Wah-Keat Lee

Canceled Seminar scheduled for 2/13/14 due to snow and will be rescheduled. Exact date is unknown but selected 3/27/14 as an estimated dated (posted by em 2/12/14). When a molten material is cooled, it typically grows into orderly crystals. But if the cooling rate is too fast for the entire melt to crystallize, the remaining material ends up in a non-crystalline state known as a glass. This talk is about the discovery and characterization of a unique metallic glass that, during rapid cooling, forms a solid by means of nucleation followed by growth normal to a moving interface between the solid and melt, with partitioning of the chemical elements. We were able to show experimentally that this is not a polycrystalline composite with nanometer-sized grains, and conclude that this may be a new kind of structure: an atomically ordered, isotropic, non-crystalline solid, possessing no long-range translational symmetry. This novel structure��"isotropic with infinite rotational symmetry and no translational symmetry��"had been considered theoretically possible, but has never before been observed.

Condensed-Matter Physics & Materials Science Seminar

"Frustration-induced phase separation and magnetoelectric effects in a triangular spin lattice"

Presented by Alexandros Lappas, Institute of Electronic Structure and Laser, Greece

Chemically homogeneous, strongly correlated transition-metal oxides, with competing states, may display phase separation when the electron charge is coupled to spin or lattice degrees of freedom. Similar nanoscale inhomogeneities in insulating spin systems are rare and poorly understood, although they have been theoretically predicted to arise from geometrical frustration already in the doping-free limit. In this respect, the spatially-anisotropic triangular spin system NaMnO2 [1, 2], provides a paradigm where fingerprints of a unique magnetostructurally inhomogeneous ground state are identified. For this purpose we review our comprehensive structural synchrotron X-ray diffraction and HAADF-STEM investigations, which are complemented by local-probe NMR and muon-spin relaxation (μ+SR) measurements, incorporating also ab initio calculations [2]. We argue that the Néel order evolves as the outcome of symmetry-breaking pinning sites (e.g. interphases) due to the local-scale inhomogeneity which is endorsed by the inherent frustrated topology of the spin lattice. Remarkably, frustration-mediated structural complexity in this manganite goes beyond the limitations of the bulk symmetry and magnetoelectricity is unveiled in an otherwise collinear magnetic system.
