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…

Self-doping and the Mott-Kondo scenario for infinite-layer nickelate superconductors
Yi-feng Yang, Guang-Ming Zhang
We give a brief review of the Mott-Kondo scenario and its consequence in the recently-discovered infinite-layer nickelate superconductors. We argue that the parent state is a self-…

Phase coherence of pairs of Cooper pairs as quasi-long-range order of half-vortex pairs in a two-dimensional bilayer system
Feng-Feng Song, Guang-Ming Zhang
It is known that the loss of phase coherence of Cooper pairs in two-dimensional (2D) superconductivity corresponds to the unbinding of vortex-antivortex pairs with the quasi-long-r…
