Equivalence of residual entropy of hexagonal and cubic ices from tensor network methods
Xia-Ze Xu, Tong-Yu Lin, Guang-Ming Zhang
The long-standing question of whether the residual entropy of hexagonal ice () equals that of cubic ice () remains unresolved despite decades of research on ice-type mode…

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 . Compared…
