Weyl–Kondo Semimetal: Towards Control of Weyl Nodes

Sarah E. Grefe, Hsin-Hua Lai, Silke Paschen, Qimiao Si

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 Ce3Bi4Pd3; and ii) describe what is expected theoretically when the time-reversal symmetry is also broken.
