Emergent superconductivity and pair density wave at antiphase boundaries of charge density wave order in kagome metals

Xianghe Han, Hui Chen, Hengxin Tan +9

Central to the layered kagome lattice superconductors AV3Sb5 (A = K, Cs, Rb) is a cascade of novel quantum states triggered by an unconventional charge density wave (CDW) order. Th…
