Weyl-Kondo Semimetal: Towards Control of Weyl Nodes

Abstract

Heavy fermion semimetals represent a promising setting to explore topological metals driven by strong correlations. In this paper, we i) summarize the theoretical results in a Weyl-Kondo semimetal phase for a strongly correlated model with inversion-symmetry-breaking and time-reversal invariance, and the concurrent work that has experimentally discovered this phase in the non-magnetic non-centrosymmetric heavy fermion system Ce${}_3$Bi${}_4$Pd${}_3$; and ii) describe what is expected theoretically when the time-reversal symmetry is also broken.
