Superconducting, Topological, and Transport Properties of Kagome Metals CsTi₃Bi₅ and RbTi₃Bi₅.

ABSTRACT: The recently discovered ATi₃Bi₅ (A=Cs, Rb) exhibit intriguing quantum phenomena including superconductivity, electronic nematicity, and abundant topological states. ATi₃Bi₅ present promising platforms for studying kagome superconductivity, band topology, and charge orders in parallel with AV₃Sb₅. In this work, we comprehensively analyze various properties of ATi₃Bi₅ covering superconductivity under pressure and doping, band topology under pressure, thermal conductivity, heat capacity, electrical resistance, and spin Hall conductivity (SHC) using first-principles calculations.
