Symmetry Origins of the Field-Free Superconducting Diode Effect in the Kagome Superconductor CsV${}_3$Sb${}_5$

Xin-Jie Liu, Shengbiao Sun, Ke-Fan Song +14

Field-free superconducting diode effects require both inversion-symmetry breaking and an internal time-reversal-symmetry (TRS) breaking field, making them sensitive probes of hidde…
