Interaction-Split Edge Spectral Flow in an Integer Hubbard Thouless Pump
Yong-Feng Yang, Zhao-Rui Tian, Chen Cheng +1
We show that local Hubbard correlations can split the open-boundary spectral flow of an otherwise integer Thouless pump. Using density-matrix renormalization group calculations for…
The antiferromagnetic Chern insulator phase in the Kane-Mele-Hubbard model
Bao-Qing Wang, Can Shao, Takami Tohyama +2
The emergence of the antiferromagnetic (AFM) Chern insulator (AFCI) phase in the Kane-Mele-Hubbard (KMH) model with a finite sublattice potential is investigated. The AFCI, charact…
Nonlinearity-Induced Thouless Pumping in Quasiperiodic Lattices
Xiao-Xiao Hu, Dun Zhao, Hong-Gang Luo
Nonlinear Thouless pumping has been established in periodic lattices; its counterpart in quasiperiodic lattices remains unexplored. Here, we show a nonlinear topological pumping of…
Topological phase in the extended Haldane-Hubbard model with sublattice-dependent repulsion
Bao-Qing Wang, Can Shao, Takami Tohyama +2
We study the ground-state phase diagram of the half-filled extended Haldane-Hubbard model on the honeycomb lattice with sublattice-dependent on-site repulsion () us…
Altermagnetism in Heavy Fermion Systems: Mean-Field study on Kondo Lattice
Miaomiao Zhao, Wei-Wei Yang, Xueming Guo +2
Recently, a novel collinear magnet, i.e. the altermagnet (AM), with spin-splitting energy band and zero net magnetization have attracted great interest due to its potential spintro…
Phase diagram of the interacting Haldane model with spin-dependent sublattice potentials
Can Shao, Hong-Gang Luo
Using the exact-diagonalization (ED) and mean-field (MF) approaches, we investigate the ground-state phase diagram of the interacting Haldane model on the honeycomb lattice, incorp…
