Paper: CsV3Sb5: A Z2 Topological Kagome Metal with a Superconducting Groundstate

December 10, 2020

Our paper discovering superconductivity in the Z2 topological metal CsV3Sb5 was published today in Physical Review Letters.  This paper reports the seminal observation of superconductivity in a 2D kagome lattice, categorizes the normal state as a Z2 topological metal with protected surface states near the Fermi level, and also observes hints of a competing charge density wave instability in this material.  This paper is featured as an editors suggestion with a writeup in APS Physics Magazine.
