dc.description.abstract
Tuning the correlation strength of electronic materials has led to the identification and classification of novel quantum phases, thereby elucidating the underlying physics. To explore how this landscape transforms in the presence of nontrivial electronic topology represents a new frontier. After a general discussion of this background I will focus on the case of gapless electronic topology driven by strong correlations. This regime can be ideally explored in heavy fermion compounds. I will introduce the first such materials class, Weyl-Kondo semimetals, and report on the giant signatures of topology and the genuine topology control that can be achieved in these materials. I will also discuss design strategies for further correlation-driven topological phases and, as an example, highlight a new emergent topological phase that nucleates out of a strange metal state.
