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…
Reexamining doped two-legged Hubbard ladders
Yang Shen, Guang-Ming Zhang, Mingpu Qin
We revisit the ground state of the Hubbard model on 2-legged ladders in this work. We perform DMRG calculation on large system sizes with large kept states and perform extrapolatio…
Comparative study of charge order in undoped infinite-layer nickelate superconductors
Yang Shen, Mingpu Qin, Guang-Ming Zhang
To understand the microscopic mechanism of the charge order observed in the parent compound of the infinite-layer nickelate superconductors, we consider a minimal three-legged mode…
An electronic origin of charge order in infinite-layer nickelates
Hanghui Chen, Yi-feng Yang, Guang-Ming Zhang +1
A charge order (CO) with a wavevector is observed in infinite-layer nickelates. Here we use first-principles calculations to demonstr…
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-…
