Classification of magnons in Rotated Ferromagnetic Heisenberg model and their competing responses in transverse fields
Fadi Sun, Jinwu Ye, Wu-Ming Liu
Competing orders is a general concept to describe various quantum phases and transitions in various materials. One efficient way to investigate competing orders is to first classif…
Hubbard model with Rashba or Dresselhaus spin-orbit coupling and Rotated Anti-ferromagnetic Heisenberg Model
Fadi Sun, Jinwu Ye, Wu-Ming Liu
In this work, we investigate the possible dramatic effects of Rashba or Dresselhaus spin-orbit coupling (SOC) on fermionic Hubbard model in a 2d square lattice. In the strong coupl…
Quantum Hall Effects in a Non-Abelian Honeycomb Lattice
Ling Li, Ningning Hao, Guocai Liu +4
We study the tunable quantum Hall effects in a non-Abelian honeycomb optical lattice which is a many-Dirac-points system. We find that the quantum Hall effects present different fe…
Layer Anti-Ferromagnetism on Bilayer Honeycomb Lattice
Hong-Shuai Tao, Yao-Hua Chen, Heng-Fu Lin +2
Bilayer honeycomb lattice, with inter-layer tunneling energy, has a parabolic dispersion relation, which causes the charge imbalance between two sublattices. Here, we investigate t…
Mott transition and Antiferromagnetic Metal on Shastry-Sutherland Lattice
Hai-Di Liu, Yao-Hua Chen, Heng-Fu Lin +2
The Shastry-Sutherland lattice, one of the simplest systems with geometric frustration, which has an exact eigenstate by putting singlets on diagonal bonds, can be realized in a gr…
Nematic Metal and Antiferromagnetic Insulator on Hexagonal Kagome Lattice
Heng-Fu Lin, Yao-Hua Chen, Hai-Di Liu +2
Hexagonal Kagome lattice is a multiband system with a quadratic band crossing point, in contrast with honeycomb lattice with linear band crossing point, which has exotic correlated…
