Topological pair density waves in kagome superconductors
Jia-Xin Yin, Xianxin Wu, Mark H. Fischer +3
The pair density wave (PDW) is an unconventional superconducting state exhibiting periodic pairing modulations due to pairing with finite momentum Q. In two dimensions, multiple Q…
Direct observation of the surface superconducting gap in the topological superconductor candidate β-PdBi2
Akifumi Mine, Takeshi Suzuki, Yigui Zhong +7
β-PdBi2 is one of the candidates for topological superconductors with a superconducting (SC) transition temperature (Tc) of 5.3 K, in which parity mixing of spin singlet and spin t…
Phase-sensitive evidence for pair density waves in a kagome superconductor
Xiao-Yu Yan, Guowei Liu, Hanbin Deng +22
Pair density wave (PDW) exhibits periodic amplitude and sign modulations of the superconducting order parameter. Such a pairing state has long been proposed to be highly sensitive…
