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…

Switchable half-quantum flux states in a ring of the kagome superconductor CsVSb
Shuo Wang, Ilaria Maccari, Xilin Feng +14
Magnetic flux quantization in units of is a defining feature of superconductivity, rooted in the charge-2e nature of Cooper pairs. In a ring geometry, the flux quantiz…
