dc.description.abstract
Gapless electronic topology driven by strong correlations is an emerging field, with heavy fermion compounds at its forefront. I will introduce the first such materials class, Weyl-Kondo semimetals [1–3], and report on the giant signatures of topology observed in Ce₃Bi₄Pd₃ [1,3] as well as the genuine topology control that can be achieved by magnetic-field tuning [4]. I will then discuss how symmetry considerations may help to identify new correlation-driven topological phases [5]. Finally, I will describe the discovery of an emergent topological phase that nucleates out of a strange-metal state [6] and discuss the potential of this new design principle for settings beyond heavy fermions [7].
