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…

Tensor network approach to the fully frustrated XY model on a kagome lattice with a fractional vortex-antivortex pairing transition
Feng-Feng Song, Guang-Ming Zhang
We have developed a tensor network approach to the two-dimensional fully frustrated classical XY spin model on the kagome lattice, and clarified the nature of the possible phase tr…

Tensor network approach to the two-dimensional fully frustrated XY model and a chiral ordered phase
Feng-Feng Song, Guang-Ming Zhang
A general framework is proposed to solve the two-dimensional fully frustrated XY model for the Josephson junction arrays in a perpendicular magnetic field. The essential idea is to…
