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.
