Precession electron diffraction (PED) in a TEM is a new emerging promissing technique using electron diffraction patterns collection very close to kinematical condition (like in x-ray diffraction) useful to solve ab-initio crystal structures of nanocrystals. TEM based 3-D diffraction tomography technique consists in a collection of a series of randomly oriented diffraction patterns in precession mode of the same crystal through the whole TEM angular range, usually from -45º to +45º, at 1º angular intervals. The resulting 3D PED set of reflections can be visualized as clear 3D picture of the reciprocal cell of the crystal and enable direct cell determination and structure determination by measuring reflections intensitities .More than 60 structures have been solved using 3D diffraction tomography the last few years dealing with nm size crystals of complex minerals, complex zeolites, MOFs , organic and pharmaceutical compounds and important application examples will be presented. PED tomography can be the ideal tool to solve crystal structures even in cases where X-Ray synchtrotron data may fail to solve the structure. Another new precession diffraction based application has been recemtly developed for a TEM based phase and orientation maps for nanocrystal (EBSD-SEM like). A TEM precession interface may perform a scanning through a sample area (typical area 5x5 m2), collecting a large number of PED patterns which are compared one by one by cross-correlation techniques with a series of generated diffraction patterns (templates) of all possible orientations of known phases existing on the sample scanned area.Resulting high quality nanoscale (1-2 nm) orientation / phase maps obtained with TEM-FEG/LaB6 are much superior to equivalent EBSD-SEM orientation maps.Such orientation/ phase maps may be produced very fast , making the technique highly attractive for high throughput TEM based orientation imaging analysis.

The vast majority of the wealth of cosmological information we have has come from power spectra (or equivalently, two-point correlation function, for the CMB temperature and for the mass distribution in the Universe today. But there is far more that can be sought in the future with the deluge of data from current and forthcoming surveys. I will discuss how the data can be used to look for new fields during inflation; to test geometrically for their properties; to seek parity breaking in the early and late Universe; to look for exotic dark-energy physics; to inquire about nontrivial cosmic topologies; to identify preferred-frame effects; etc. I will also draw connections to some of the possible CMB anomalies.

With the start of the Large Hadron Collider (LHC) at CERN, particle physics entered a new era. The LHC will provide a deeper understanding of the universe and the insights gained could change our view of the world, and the talk will present some of the reasons for the excitement surrounding the LHC. The LHC is expected to yield insights into the origin of mass, the nature of dark matter and into many other key questions. This lecture will address the exciting physics prospects offered by the LHC, present first results, in particular the recent discovery of a new 'Higgs-like' Boson, and also a look forward.

The presentation will focus both on scientific and technical aspects of modern angle-resolved photoemission spectroscopy (ARPES). In the firs part I will provide a brief introduction into ARPES, explaining why it has evolved into an indispensable experimental technique, when a basic band structure and/or many-body effects of a new material has to be studied. As an illustration several particular studies will be provided, focused on: (1) renormalization effects in hole doped Bi-122; (2) superconductivity and renormalization in YBa2Cu3O7'δ; (3) origin of pseudogap in electron doped Pr2'xCexCuO4; (4) stripe phase in La1.8'1/8Eu0.2Sr1/8CuO4 ; and finally (5) peculiarities of electronic structure of Ba1-xKxFe2As2 and LiFeAs. The second part of my presentations will cover certain aspects of 13 ARPES end-station development at BESSY and argumentation for introduction micrometer (or better) lateral resolution in angle-resolved photoemission spectroscopy.

An approach to the formulation of chiral gauge theories on the lattice is to start with a vector- like theory, but decouple one chirality (the "mirror" fermions) using strong Yukawa interactions with a chirally coupled "Higgs" field. While this is an attractive idea, its viability needs to be tested with nonperturbative studies. The model that we studied here, the so- called "3-4-5" model, is anomaly free and the presence of massless states in the mirror sector is not required by anomaly matching arguments, in contrast to the "1-0" model that was studied previously. I will talk about the results we got from the study of the "3-4-5" model, which does not suggest the decoupling of the mirror fermions and therefore no emergence of the chiral gauge theory.

Block copolymer self assembly is a particularly convenient method for fabricating nanostructured materials and devices, having the ability to spontaneously form regular patterns over arbitrarily large areas with feature sizes in the range of 10 nanometers. Because block copolymers can be processed in a manner similar to polymer photoresists, they are used by our group and many groups throughout the world to build nanostructures by combining with more conventional top-down fabrication approaches. Several CFN staff members have significant experience and knowledge of block copolymers, and we should consider use of these materials as a strategic scientific strength of our center. I will describe some of our current projects using block copolymers to fabricate nanostructures for solar devices, as well as new directions we will pursue in the near future. A goal of my presentation will be finding other ongoing or planned CFN research that can benefit from the types of structures we can fabricate by this approach.

The discovery of graphene, a unique two- dimensional electron system with extraordinary physical properties, has ignited tremendous research activity in both science and technology. Graphene can be obtained from graphite by moving its top layer until it becomes locally decoupled from the bulk. However, a detailed microscopic understanding of this process has yet to be completed. Here a series of measurements on HOPG surface using a technique called electrostatic-manipulation scanning tunneling microscopy (EM-STM) are presented. These measurements successfully reduce the interplanar coupling strength between top plane of graphite and the bulk resulting in transition from graphite to graphene. In addition, STM images which reveal several intermediate stages in between pure graphene and pure graphite are also presented. Density functional theory was used to simulate STM images from a six-layer slab of graphite. A continuous transition from pure graphite to pure graphene was observed with the simulations.

Imaging Anti-Ferromagnetic A-type domains in strongly correlated LaSr2Mn2O7 Mirian García-Fernández Supervisor: Stuart B. Wilkins Abstract: Strongly correlated electron systems display a wide range of potentially useful properties. In these systems the correlation of electrons results in very rich phase diagrams with different and interesting ground states. As a consequence of the competition between different phases, very interesting properties like superconductivity and colossal magnetoresistance can occur. This competition between phases leads to electronic domains and inhomogeneities over a range of real-space length scales, from nanometers to hundreds of microns. Understanding the role that these domains play in defining the properties of strongly correlated electron systems appears as a mandatory requirement in order to achieve a full understanding of these systems. Among one of the most challenging properties to be studied in these materials antiferromagnetic order, one of the most ubiquitous ground states. The absence of any net magnetic moment from antiferromagnetic domains prohibits the use of most magnetic imaging techniques. Here we present results from a new imaging technique, soft x-ray resonant nano-diffraction. Reciprocal-space resolved soft x-ray diffraction, sensitive to long range electronic ordering, with a nano sized x-ray probe, focused by a Fresnel zone plate is used to study A-type antiferromagnetic (AFM) domains in La0.96Sr2.04Mn2O7. The existence of two different A-type AFM regions in the sample is demonstrated. These regions have the same magnetic Q-vector, but differing orientations of the ordered moment, at 90 degrees to one another. The two regions have an unequal population, and when studied in retail, they are found not to be symmetry related. Further, we found that one of the regions exhibits a type of fine structure that is absent in the other region. A possible explanation f

I discuss how global QCD fits of parton distribution functions can make the somewhat separated fields of high-energy particle physics and lower energy hadronic and nuclear physics interact to the benefit of both. In particular, I will argue that large rapidity gauge boson production at the Tevatron, RHIC and the LHC has the highest short-term potential to constrain the theoretical nuclear corrections to DIS data on deuteron targets necessary for up/down flavor separation. This in turn can considerably reduce the PDF uncertainty on cross section calculations of heavy mass particles such as $W'$ and $Z'$ bosons.

Bimetallic nanoparticles are promising candidates for electro- and heterogeneous catalysis because their catalytic activity is frequently superior to their monometallic counterparts. However, the additional degree of freedom introduces a new complexity into the mechanism because the distribution of the two metals may vary during reaction. For example, preferential adsorption of reactive molecules can induce segregation of one component, structural changes, and element-specific phase transformations. Uncovering the chemistry, structure, and degradation pathways of materials under catalytic conditions is of fundamental importance for establishing structure-property relationships and for the design of new catalytic materials. Aberration-corrected scanning transmission electron microscopy (STEM), in combination with electron energy loss spectroscopy (EELS), is exquisitely poised for studying structural, compositional, and electronic properties of nanocatalysts. The enlarged numerical aperture coupled with the use of a cold-field-emission gun allows for the acquisition of 2-D compositional and bonding maps of both bulk and nanostructured materials at atomic resolution. Additionally, the development and inclusion of differentially-pumped gas cells inside a transmission electron microscope (TEM) permits the visualization of solid-gas chemical reactions in situ. Imaging atomic-scale reaction dynamics and the acquisition of spectroscopic fingerprints allows us to reveal reaction pathways that cannot be resolved by any other approach. Here, I will provide background on our techniques, including STEM, EELS, electron tomography, and in situ environmental methods, and I will show how the surface and internal structures of Pt-transition metal bimetallic nanocatalysts reconstruct in response to annealing, acid leaching, operational aging, gas oxidation, and reduction. I will also discuss the current challenges and future prospects for quantitative environmental TEM.

Macromolecular crystallisation is often a long and iterative process where initial promising conditions are optimised until crystals suitable for the diffraction experiments are obtained. Crystallisation is in most cases separated from the diffraction experiment, and crystals are more often than not optimised on the basis of their appearance, due to the difficulty in cryocooling and shipping every potential sample to the synchrotron. The objective for a new in situ beamline is to include and develop in situ analysis (diffraction with the crystal still in the crystallization chamber) seamlessly within existing crystallisation pipelines and provide an entirely automated facility for the characterisation of crystallization experiments, and data collection directly from crystals, in situ. High photon flux will enable fast data collection and the possibility to outrun radiation damage. Higher flux can be achieved by using multilayer optics which would deliver a broader bandpass beam. Such a beam would in addition simplify the screening mode as still images would contain relatively more diffraction spots, reducing the need for oscillation images. Beamlines with beams of between 5 and 20 mmicrons in size, and photon fluxes exceeding, 10^12 ph/s, are now available at most 3rd generation synchrotron sources. Their impact has been profound since they have enabled high quality data to be measured from small, poorly ordered, inhomogeneous and weakly diffracting crystals of membrane proteins, large macromolecular complexes and viruses. It has been demonstrated that datasets can be measured and compiled from crystals as small as 1.3 microns in non-optimal conditions using a 5 x 5 micron beam at Diamond beamline I24. Combined with the demonstration that X-ray free electron lasers can yield diffraction data from crystals <500 nm in size there is great potential for the use of submicron beams at synchrotrons with

The observation of a long-range, near-side two-particle angular correlation in very high multiplicity proton-proton (pp) and proton-lead (pA) collisions at the LHC has changed our view of multiparticle production in these small systems. This phenomenon, known as the "Ridge", was first seen in high energy nucleus-nucleus (AA) collisions at RHIC, and is believed to be related to the collective evolution of a strongly interacting QCD matter created in AA. In this talk, I will first briefly review the history of ridge studies in AA and unexpected discovery of the ridge correlations in pp and pA systems. Focus will then be given to the most recent results of pA collisions at CMS from 2013 LHC run on two- and multi-particle correlations. I will discuss the new insights these results provide us toward disentangling different theoretical interpretations (i.e. CGC v.s. flow) to the physical origin of the ridge phenomenon in small systems of pp and pA.

Electron diffraction techniques are versatile method that can be employed to study many fundamental questions of crystal structure. In this presentation, I will introduce two important diffraction methods and their application in crystallography and material science. First topic is quantitative energy-filtered convergent beam electron diffraction (QCBED). It can be employed to measure the low order structure factor amplitudes and phases of microcrystals of known structure very accurately. Many difficulties of X-ray diffraction, such as extinction corrections, absorption corrections and scaling problems are avoided in electron diffraction. The accuracy is equivalent to that of the X-ray Pendullösung method, allowing the covalent and ionic contributions to be separately visualized. Accurate structure factors of Cu, GaN, AlN, SrTiO3, TiO2, Mg have been measured by QCBED. The measurement standard deviations are normally less than 0.2% for both amplitudes and phases of low order structure factors. Thus, accurate charge density maps have been obtained and the bonding character has been studied. Second topic is electron diffractive imaging. Diffractive imaging uses diffraction intensity and phase retrieval to form real-space images. Nanodiffraction patterns from carbon nanotubes and nanoparticles are recorded, and then a fienup algorithm is used to retrieve phases of these diffraction patterns to reconstruct atomic structure of these nanotubes and nano-particles. This lensless diffraction imaging method avoids the resolution limitation owning to objective lens aberration, and can enhance the resolution of TEM to sub-angstrom level using a conventional FEG gun TEM.

We have the current best constraints showing quasar clustering does not appear to be dependent on the quasar luminosity, completely unlike what is seen with galaxies. I will also describe how we are using these measurements to further understand quasar properties, such as how they occupy dark matter halos and if their environment can provide clues on their formation and evolution.

Effector proteins are exported to the interior of host cells by numerous plant pathogens. Effector proteins have been well characterized in bacteria. Contrastingly, the mechanisms through which these effectors promote virulence are largely unknown. Bioinformatic analysis of genome sequences from oomycete pathogens Phytophthora sojae, P. ramorum, P. infestans and Hyaloperonospora arabidopsidis (Hpa) have led to the identification of a large number of candidate effector genes. These effector genes have characteristic motifs (signal peptide, RxLR and dEER) that target the effectors into plant cells. Although these effector genes are very diverse, certain genes are conserved between P. sojae and H. arabidopsidis, suggesting that they play important roles in pathogenicity. The goal of my first project was to characterize a pair of conserved effector candidates from Hpa and P.sojae. We hypothesized that these effectors have important conserved roles with regard to infection. We found that the Hpa effector was expressed early during the course of infection of Arabidopsis and triggered an ecotype-specific defense response in Arabidopsis, suggesting that it was recognized by host surveillance proteins. Both the effectors from Hpa and P. sojae respectively could suppress immunity triggered by pathogen associated molecular patterns (PTI) and by effectors (ETI) in planta. They also enhanced bacterial virulence in Arabidopsis when delivered by the Type III secretion system. Similar results were seen with experiments with transgenic Arabidopsis expressing the effectors.

Born in core-collapse supernovae, neutron stars contain matter at densities far beyond the ground state density of atomic nuclei. Measurements of neutron star properties, such as their masses and radii offer intriguing possibilities to probe the properties of dense nuclear matter like its compressibility and the nuclear symmetry energy. The composition of matter under neutron star conditions is currently unknown, but theoretical predictions range from pure nucleonic matter to the presence of hyperons or deconfined quarks. Since the appearance of hyperons or quark matter is often associated with a softening of the nuclear equations of state (and thereby low neutron star masses), the recent finding of a pulsars with masses of around two solar masses reignited the debate of whether hyperons or quarks can exist in neutron star interiors. However, various studies suggest that both quarks and hyperons can have stiff equations of state and therefore populate the interior of high mass stars. As a consequence, the question about the composition of high density neutron star matter remains undetermined. It is a continuing challenge for astrophysical and nuclear theory, experiment, and observations to determine clear constraints and signatures that would be able to confirm or exclude different neutron star compositions. With this in mind, I will discuss possible impacts of quark matter in neutron star interiors and core-collapse supernovae.

The dilute Fermi gas at unitarity is scale invariant and its bulk viscosity vanishes. We compute the leading contribution to the bulk viscosity when the scattering length is not infinite. A measure of scale breaking is provided by the ratio P-2/3E, where P is the pressure and E is the energy density. In the high temperature limit this ratio scales as z/a, where z is the fugacity and a is the scattering length. We show that the bulk viscosity scales as the second power of this parameter.

The recent progress made in devising chemical methods for the synthesis of defect-free one-dimensional and two-dimensional organic nanosystems with reproducible properties has prompted an enormous interest in developing a quantitative understanding of the assembly process and the resulting intrinsic properties of the structures ad they interact with their environment. In this presentation, I will review a number of examples where theoretical nanoscience and computational sciences can be used to account for experimental findings and to predict emergent properties in a range of systems. Spin-depending electronic transport, thermoelectricity, heterostructures, chemical doping, effects of substrate, will be discussed and placed in the perspective of the general objective of designing materials with tailored properties. In each case, success and failure of atomistic theories, ranging from self-consistent tight-binding, density functional theory, and many-body perturbation theory, will be discussed within the context of current developments in their respective fields.

The recent WMAP data not only have confirmed the previously existing gravitational evidence for the presence of dark matter in galactic halos, but they have also shown that this type is the dominant form of mater in the Universe. Modern particle theories provide viable cold dark matter candidates with masses in the GeV-TeV region. All such candidates are called WIMPs (Weakly Interacting Massive Particles). The nature of dark matter, however, can only be unraveled by its direct detection in the laboratory. Since the WIMPS have an average energy in the keV region, they cannot excite the nucleus and their detection consists of measuring the nuclear recoil energy. We will discuss all factors contributing to the event rate, namely : i) the nucleon cross section, which depends on particle physics information, ii) the WIMP velocity distribution and iii) the relevant nuclear structure. The experiments are hard, since the expected cross sections are small and the signal spectrum cannot be easily distinguished from the background. None of the experiments has yet detected dark matter, but the impressive limit on the coherent nucleon cross section of  10'44cm2 = 10'8pb has been reached, assuming that it is dominant. Limits which are 4 orders of magnitude larger have also been reached for the spin induced cross sections. The two modes cannot be separated in a single target experiment. We will show, however, that given a judicious choice of at least three odd mass targets one may be able to extract from experiments all three nucleon cross sections (coherent as well as the proton and neutron spin induced). For an unambiguous detection of dark matter one would like exploit some characteristic signatures of the reaction. These are a) The modulation effect, i.e. the time dependence of the rate due to the Earth's annual motion and b) rhe correlation of the event rates with sun's direction of motion in directional experiments, i.e. those that

Electric polarizability measures the ability of the electric field to deform a particle. Experimentally, the electric and magnetic polarizabilities can be measured in Compton scattering experiments. To compute these quantities theoretically we need to understand the internal structure of the scatterer. For hadrons — bound stated of quarks and gluons — this is a very difficult problem since their internal structure cannot be parametrized easily. While quantum chromodynamics describes accurately the interactions between quarks and gluons, direct computations of hadron properties in terms of the quark degrees of freedom are very challenging. In this talk I will show how to use lattice QCD to extract the electric polarizability of hadrons, outlining both the theoretical and computational challenges we must overcome to arrive at the final answer.

The measurement of $W^{\pm}$ production in polarized proton-proton collisions at RHIC is an important probe of the proton's polarized sea quark distributions which are poorly constrained at present compared to the valence quarks distributions. Parity-violating single-spin asymmetries, $A_{L}$, measured in $W^{\pm}$ production in longitudinally polarized $p+p$ collisions provide access to the flavor-separated light quark and anti-quark polarized parton distribution functions. The PHENIX experiment observes $W^{\pm}$ through their leptonic decay to $e^{\pm}$ at mid-rapidity ($|\eta|<0.35|$) and to $\mu^{\pm}$ at forward/backward rapidities ($1.2<|\eta|<2.2$). These complementary measurements give access to the sea quark polarizations over different ranges in partonic momentum of a quark/antiquark. In succession to the first measurements performed in 2009 (mid-rapidity) and in 2011 (forward/backward rapidities), in 2012 PHENIX recorded data at $\sqrt{s}$ = 510 GeV with an integrated luminosity of $\approx$50 pb$^{-1}$ which is about twice the size of previous data sets and also takes an advantage of improved beam polarization ($P\approx$ 55$\%$). The parity-violating single-spin asymmetries for $W$ production from the 2012 dataset will be presented; as well as, details and status of the recent analyses and future prospects will be reported.

Development of sustainable energy technologies requires new materials with properties tailored for specific needs. Nano-phase-separation observed in many material systems opens a wide range of possibilities for manipulating specific properties as well as for creating new properties not observed in homogeneous systems. Generally, targeted material design requires an understanding of underlying structure. One important example of nanophase-separated system is a polymer electrolyte membrane (PEM). In PEM a hydrophilic phase provides charge transport while a hydrophobic phase is responsible for mechanical properties and stability of the material. The geometry of phase separation governs performance of membrane providing continuous pathways for charge transfer. The goal of my research is to determine the structure of conductive pathways and to design a membrane with maximum connectivity in the hydrophilic phase. This goal can be achieved by exploiting self-organization in block copolymers that produces naturally aligned nano-sized phases. This approach has already allowed us to overcome difficulties in electron microscopy imaging of ionomer morphology and to report the first direct observation of sulfur clusters in PEM. Using a block copolymer system, we have shown that the clustering reduces conductivity of the ionomer and suggested a way to reduce clustering by decreasing the size of conductive domains. The next step towards development of an improved membrane material is determining water distribution in PEM which may be achieved by advanced electron microscopy techniques.

The dilute Fermi gas at unitarity is scale invariant and its bulk viscosity vanishes. We compute the leading contribution to the bulk viscosity when the scattering length is not infinite. A measure of scale breaking is provided by the ratio P-2/3E, where P is the pressure and E is the energy density. In the high temperature limit this ratio scales as z/a, where z is the fugacity and a is the scattering length. We show that the bulk viscosity scales as the second power of this parameter.

Presented by Kazuhisa Kakurai, Quantum Beam Science Directorate, Japan Atomic Energy Agency, Japan

Monday, June 10, 2013, 11:00 am

In studying modern functional materials, one is often confronted with complex spin configurations, for example, non-collinear, incommensurate magnetic structure such as helimagnetic structure as a result of frustrated magnetic interactions. Since the giant functional responses in these materials are direct consequences of these complicated magnetic structures, the detailed knowledge of the structure is mandatory to understand the essence of the magnetic functional materials. In this seminar talk I would like to present some polarized neutron studies on magneto-electric materials with complex magnetic structures. These include investigations on complex multiferroic behaviour in RMn2O5 (R: rare earth elements) compounds, on ferroelectricity induced by a proper screw-type helical ordering in CuFeO2 and on transverse conical structure in hexaferrites showing a route to the possible RT functional multiferroic systems. These invetigations were performed in collaboration with S. Wakimoto, M. Matsuda, M. Takeda, Quantum Beam Science Directorate, Japan Atomic Energy Agency, Japan, N. Terada, H. Kitazawa, National Institute for Materials Science, Tsukuba, Japan, , T. Nakajima, S. Mitsuda, Dep. of Physics, Tokyo University of Science, Japan, S. Ishiwata, D. Okuyama, Y. Taguchi, Y.

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. The traditional trial-and-error approach to developing first-wall material and component solutions for current and future fusion devices is becoming prohibitively costly because of the increasing device size, curved toroidal geometry, access restrictions, and complex programmatic priorities. The experimentally validated atomistic theory and computation for studying the dynamics of the creation and evolution of the PMI under irradiation by heavy particles (atoms, molecules) at carbon, lithiated carbon and tungsten, as well as the emerging elastic and inelastic processes, in particular retention and sputtering chemistry will be presented. The National Institute of Health research initiatives over the past ten years resulted in the reduction of the human DNA sequencing cost by more than 100,000 times, reflecting the highest rate of progress in history of science. This research still requires development of fast, label-free and cheaper technologies, which can be massively produced and used. Particularly interesting is the prospect of the so-called physics-based third-generation methods, since they are intrinsically fast and can operate on a single DNA OR protein polymer. Multiscale theory and computation, with predictive powers for localization, control, detection and recognition of biomolecules in nanofluidic environment will be presented. Predrag Krstic is senior research scientist of Joint institute of Computational Sciences and adjunct professor of physics at Department of Physics and Astronomy of University of Tennessee, founder of TheoretiK Consulting, till recently senior staff scientists at Oak Ridge National Laboratory. Dr. Krstić completed his PhD degree at City College of C.U.N.Y on the multiphoton theory,

Nuclear Physics & RIKEN Theory Seminar

"From the QCD flux tube to the integrable theory of quantum gravity and back"

Presented by Sergei Dubovski, NYU, Physics Department

2 pm, Small Seminar Room, Bldg. 510

Friday, June 14, 2013, 2:00 pm

We propose a new approach for the calculation of the spectrum of excitations of QCD flux tubes. It relies on the fact that the worldsheet theory is integrable at low energies. The corresponding integrable model features a number of surprising properties characteristic for gravity rather than for conventional field theory. These include the absence of local off-shell observables, a minimal length, a maximum achievable (Hagedorn) temperature, as well as black hole precursors. It exhibits a new type of renormalization group flow behavior, "asymptotic fragility". With this approach, energy levels can be calculated for much shorter flux tubes than was previously possible, allowing for a quantitative comparison with existing lattice data. The improved theoretical control makes it manifest that existing lattice data provides strong evidence for a new pseudoscalar particle localized on the QCD fluxtube - the worldsheet axion.

"The truth and beauty in quasicrystals"

Presented by Marjorie Senechal, Smith College

4 pm, Berkner Hall Auditorium

Thursday, October 17, 2013, 4:00 pm

Hosted by: Vivian Stojanoff

The truth and beauty in quasicrystals Abstract: Like mosaics observed in our childhood kaleidoscope, quasicrystals show remarkable patterns that can not be repeated in a regular manner. Discovered in 1982 quasicrystals are very hard and break easily, like glass. Due to their unique properties they can be used to convert heat into electricity, in surface coatings for frying pans, or can be used in energy saving LED's. In this talk Senechal, Louise Wolf Kahn Professor Emerita in Mathematics and History of Science and Technology at Smith College, and Fellow of the American Mathematical Society, will discuss the beauty and applications of the patterns observed in artificial and natural quasicrystal structures.
