Nonreciprocal impurity scattering as a probe for pairing symmetries in kagome superconductors

Hong-Min Jiang, Hao Du, Shun-Li Yu

The superconducting (SC) pairing symmetry and its link to time-reversal symmetry breaking (TRSB) in the vanadium-based kagome superconductors remain unresolved, with ambiguities st…
