Theory of charge-6e condensed phase in Kagome lattice superconductors

Tong-Yu Lin, Feng-Feng Song, Guang-Ming Zhang

We develop a Ginzburg-Landau theory for commensurate pair density wave (PDW) states in a hexagonal lattice system, relevant to the kagome superconductors $\mathrm{A}{\mathrm{V}}_3\mathrm{S}{\mathrm{b}}_5$. Compared…
