Symmetry Origins of the Field-Free Superconducting Diode Effect in the Kagome Superconductor CsVSb
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…

Large Field-Free Superconducting Diode Effect with Nonmonotonic Polarity Reversals in NbSe/CrBr Heterostructures
Shengbiao Sun, Lang Xiao, Chenghao Shen +10
The superconducting diode effect (SDE), characterized by nonreciprocal dissipationless supercurrent, offers a promising route toward ultralow-power superconducting electronics. Yet…
