Rich nature of Van Hove singularities in Kagome superconductor CsV3Sb5
Abstract The recently discovered layered kagome metals AV 3 Sb 5 (A = K, Rb, Cs) exhibit diverse correlated phenomena, which are intertwined with a topological electronic structure with multiple van Hove singularities (VHSs) in the vicinity of the Fermi level. As the VHSs with their large density of states …
