    Complexity in transition metal oxides is the outcome of simultaneously active electron degrees of freedom (spin-charge-orbital) and their evolution under the restrictions imposed by the geometry of the underlined crystal lattice. Consequently, the materials' response to competing states requires that we assess structural correlations across a wide range of length and time scales. Taking advantage of cutting-edge structural facilities accessed at neutron [1, 2], synchrotron X-ray [3] and electron microscopy [4] labs we address current limitations in understanding the crystallographic structure of layered rock-salt type triangular-lattice manganites of the AMnO2 type (A= Na, Cu). The unexpected coexistence of long- and short-range magnetic correlations [3, 5] due to two major opposing effects (elastic vs. magnetic exchange) of similar magnitude, lead to nearly equivalent, competing structural phases enabling infinitesimal quenched disorder to locally lift the differing degree of inherent frustration in the parent AMnO2 phase. These manganites provide a paradigm of a rarely observed nanoscale inhomogeneity in an insulating spin system, an intriguing complexity of competition due to geometrical frustration. The dramatic impact of topology and site-disorder on frustrated magnetism is further demonstrated by the hydrated variant of the NaMnO2 antiferromagnet, which gives way to a strongly interacting spin-glass state, indicative of the subtle balance of competing processes in multivalent two-dimensional systems [6].

  3. CFN Colloquium

    4 pm, CFN, Bldg 735, Seminar Room, 2nd Floor

    Hosted by: ''''Matthew Sfeir''''

    Hybrid (inorganic-­-organic) perovskites have demonstrated an extraordinary potential for clean  sustainable  energy  technologies  and  low-­-cost  optoelectronic  devices  such  as  solar  cells; light emitting diodes, detectors, sensors, ionic conductors etc. In spite of the unprecedented  progress  in  the  past  six  years,  one  of  the  key  challenges  that  exist  in  the  field today is the large degree of processing dependent variability in the structural and physical  properties.  This  has  limited  the  access  to  the  intrinsic  properties  of  hybrid  perovskites and led to to multiple interpretations of experimental data. In addition to this, the stability and reliability of devices has also been strongly affected and remains an open question,  which  might  determine  the  fate  of  this  remarkable  material  despite  excellent  properties. In this talk, I will describe our recently discovered approach for thin-­-film crystal  growth  as  a  general  strategy  for  growing  highly  crystalline,  bulk-­-like  thin-­-films  of  both three-­-dimensional (3D) and layered two-­-dimensional (2D) hybrid perovskites that overcomes the above issues by allowing access to the intrinsic charge and energy transport processes  within  the  perovskite  thin-­-films  and  results  in  reproducible  and  stable  high  performance optoelectronic devices.

    The large scale structure of the universe forms a particular type of fluid which is governed by the properties of dark matter. I discuss how one can derive renormalization group equations for the effective action that describes the statistical properties of this fluid. Taking into account in particular effective viscosity and sound velocity terms leads to an improved framework to determine density and velocity power spectra.

    Hosted by: 'Oleg Eyser'

    Heavy quark pair production in high energy proton-nucleus (pA) collisions provides valuable information on the gluon saturation dynamics at small-x of a heavy nucleus. Nowadays, large amounts of data of quarkonium, open heavy flavor, and decay lepton accumulated by RHIC and LHC enable us to examine the calculations in Small-x formalism or Color Glass Condensate (CGC). Essentially, the calculations of heavy quark pair production have been based on the Small-x/CGC framework at leading order (LO) with the running coupling Balitsky-Kovchegov equation (rcBK) which includes a subset of next-to-leading order (NLO) correction. A main difference between pp and pA collisions is the choice of the initial saturation scale in the rcBK equation. The recent theoretical computations have gradually clarified the gluon saturation effect in pA collision by comparing with data on the transverse momentum spectrums and the nuclear modification factors measured at RHIC and LHC. In this talk, we will review the recent studies of heavy quark pair production in the Small-x/CGC framework and discuss the relevant topical issues. Furthermore, we will discuss the Sudakov implementation in Small-x formalism which has received attention in recent years. I will show that the Sudakov effect on top of the saturation effect is indeed indispensable for Upsilon production.

    Squeeze out happen when the expanding central fireball flows around a large surface flux tube in a central Au-Au collision at RHIC. We model such an effect in a flux tube model. Two particle correlations with respect to the $v_2$ axis formed by the soft fireball particles flowing around this large flux tube is a way of measuring the effect.

    Presented by Dr. Thomas Junk, Fermilab

    Thursday, January 12, 2017, 3:00 pm

    Hosted by: 'Xin Qian'

    Current and planned neutrino experiments address fundamental questions in the neutrino, astrophysical, nuclear, and new physics sectors with ambitious, large-scale facilities and detectors. Maximizing the sensitivity and physics reach of these experiments is the guiding principle for the design of the apparatus as well as the analysis techniques applied to infer results from the data. These experiments, however, pose challenges in this process: the data frequently have ambiguities and some quantities are not measurable, such as the momenta of outgoing neutrinos or recoiling nuclei. Detectors with high density and spatial granularity provide a large number of measured values for each event that must be sifted through to obtain even basic reconstructed quantities. The impact of the values of model parameters on the predicted event rates is not linear but is frequently oscillatory. Systematic uncertainties must be highly constrained in order to tease out small effects. To address these challenges, a variety of sophisticated techniques have been adapted from earlier experiments, such as well-established statistical methods and analysis techniques. New, innovative tools developed in other fields, such as deep-learning methods, are being applied to neutrino experiments. I will give a survey of some of the interesting developments being applied and planned for the future.

    "Creation and Control of Low Dimensional Electron System in Transition Metal Oxides"

    Presented by Milan Radovic, Paul Scherer Institut, Switzerland

    11 am, Building 734, conference room 201

    Monday, January 23, 2017, 11:00 am

    Hosted by: '''Cedomir Petrovic'''

    Transition Metal Oxides (TMOs) exhibit unique and multifunctional electronic properties (such as high-temperature superconductivity, colossal magnetoresistance, metal-insulator transitions, etc.) directly related to the spin and orbital degrees of freedom of the transition metal d-states. Furthermore, their iso-structural nature permits realization of heterostructures where novel unexpected electronic properties take place. Engineering transition metal oxide surfaces and interfaces carries the potential for achieving new physical properties that radically differ from those of the constituent bulk materials. This is the case of oxide-lowDEGs, which recently showed extraordinary occurrences, including interfacial superconductivity, magnetism, large tuneable spin-orbit coupling and indications of topological states. In my talk, I will present recent spin resolved Angle Resolved Photoemission Spectroscopy (ARPES) measurements of the low dimensional electron gas at SrTiO3 [1, 2, 3], TiO2-anatase and Sr1-xBaxTiO3 showing that these materials have capability for the realization of TMO based electronic device.
