Higgs-Leggett mechanism for the elusive 6e superconductivity observed in Kagome vanadium-based superconductors

Ling-Feng Zhang, Zhi Wang, Xiao Hu

A recent Little-Parks experiment on Kagome-structured superconductor CsV_3Sb_5 demonstrated remarkable resistance oscillations with period \phi0/3=hc/6e. Here, we perform analysis…
