Illuminating Signatures of Gapless Topology and Correlations - Contrasting Nonlinear Optical Responses

Explore a 42-minute conference talk by Sarah Grefe from Los Alamos National Laboratory on "Illuminating signatures of gapless topology and correlations: contrasting nonlinear optical responses." Delve into recent developments in the interplay between topology, symmetry, and interactions in quantum materials. Examine the effects of correlations on topological insulators, semimetals, and superconductors. Investigate how symmetry and strong correlations produce topological phases in Kondo systems. Learn about the connection between higher-order topology and fracton systems, and explore the potential of topology as a framework for understanding strongly correlated gapless phases. Gain insights into unifying themes for electronic topology across various materials and correlation strengths. This talk is part of a broader conference organized by the Kavli Institute for Theoretical Physics, aiming to enhance cross-talk between weakly and strongly correlated communities interested in topology.
