CorTopS - Correlation-driven topological semimetals
Abstract
The past decade has seen a wealth of developments in what we now call topological quantum matter. In quantum materials, much progress has been made on noninteracting and weakly interacting topological insulators and (semi)metals and on strongly correlated gapped topological phases. Gapless topological phases driven by strong correlations, however, are a vastly open field. Its full exploration is of great interest because one expects the rich landscape of strongly correlated metals in conjunction with nontrivial topology to be fertile ground for breeding novel quantum phases. The PI and her team, together with international collaborators, have recently discovered one such correlation-driven gapless topological phase, the Weyl-Kondo semimetal , and revealed its extreme topological responses as well as the ability of genuine topology control by external parameters. These results represent a proof of principle that new phases with unexpected properties can be generated by the interplay of strong correlations and topology. This sets the stage for the present project.
