PIRSA:11040089  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Electronic liquid crystal phases of strongly correlated systems
Speaker(s): Eduardo Fradkin
Abstract: It is a generic feature of strongly correlated electronic systems that several mechanisms (broadly represented by interactions) compete with each other. This competition often leads to the phenomenon of frustration. In strongly correlated systems such as doped Mott insulators kinetic energy and Cou... read more

Disorder-induced zero bias anomalies in strongly correlated systems
Speaker(s): Rachel Wortis
Abstract: Many of the most interesting electronic behaviors arise in materials with strong electron-electron correlations. Many of these same materials are disordered either intrinsically or due to doping. The combination of disorder and interactions generally gives rise to a feature in the density of states ... read more

Resonant soft x-ray scattering in stripe ordered Nd-LaSrCuO
Speaker(s): David Hawthorn
Abstract: Recently resonant elastic soft x-ray scattering (RSXS) has emerged as a powerful new tool to study electronic ordering in materials like cuprates and manganites. The power of this technique is to combine xray scattering, which is sensitive to spatial order, with x-ray spectroscopy, which is sensiti... read more

The secret within
Speaker(s): Seamus Davis
Abstract: Direct visualization of the electronic structure within each crystalline unit cell of a solid is a new frontier in condensed matter physics (M.J. Lawler et al, Nature 466, 347 (2010)). In this talk, I will introduce the techniques of spectroscopic imaging scanning tunneling microscopy (SI-&Ati... read more

PIRSA:11040093  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Superconducting gap symmetry in iron-pnictide superconductors: a thermal conductivity perspective
Speaker(s): Robert Hill
Abstract: The nature of the pairing mechanism in the recently discoverediron-pnictide family of superconductors remains an outstanding issue. To answer this question, it is instructive to know the symmetry of the superconducting energy gap. Low temperature thermal conductivity measurements provide a robust te... read more

Theory of quantum Hall effect in bilayer grapheme
Speaker(s): Volodya Miransky
Abstract: Utilizing the Baym-Kadanoff formalism with the polarization function calculated in the random phase approximation, the dynamics of the ν=0, ±1, ±2, ±3, &... read more

Quantum fluctuations in spin ice
Speaker(s): Graeme Luke
Abstract: Geometrical frustration in magnetic systems provides a rich playground to study the emergence of novel ground states. In systems where not all magnetic couplings can be simultaneously satisfied, conventional long range magnetic order is often precluded, or pushed to much lower emperature scales than... read more

PIRSA:11040096  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Dynamics of the magnetic susceptibility deep in the Coulomb phase of the dipolar spin ice material Ho2Ti2O7
Speaker(s): Jan Kycia
Abstract: Very recently, it has been recognized that excitations out of the ground state of materials known as spin ice can be viewed as magnetic monopoles, the magnetic analog to electric charges. Like electrons and positrons, these particles possess a charge of +Q or -Q and therefore attract or repel each ... read more

PIRSA:11040097  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Ordering in the Spatially Anisotropic Heisenberg Model on a Triangular Lattice
Speaker(s): Catherine Kallin
Abstract: The spin 1/2 Heisenberg model on a triangular lattice with interchain exchange, J', weaker than the intrachain exchange J, is a particularly well-studied frustrated magnet because of its relevance to Cs2CuCl4, which is thought to be in close proximity to a spin liquid phase. Although an incomensurat... read more
