Event Description

Three important driving forces for creating qualitatively new phases in quantum materials are the topology of the materials’ electronic band structures, frustration in the electrons’ motion or magnetic interactions, and strong correlations between their charge, spin, and orbital degrees of freedom. In very few material systems do all of these aspects come together to contribute on an equal footing to stabilize new electronic states with unprecedented properties; however the search for such systems can be guided by configurational motifs that can host such physics. One of the prevalent platforms for realizing this rich interplay of frustration, electronic topology, and electron correlation effects is the kagome lattice, composed of corner-sharing triangles as the key structural motif.  In this talk, I will provide an overview of the theoretical underpinnings that enable unconventional electronic orders in kagome networks, with a focus on AV3Sb5 compounds and their unconventional charge order, and discuss experimental progress in realizing novel states intrinsic to kagome lattices in these materials.
