Zeeman field induced corner states in the Kane-Mele-Hubbard model
Jie Zhang, Han Xu, Yu Wang
We investigate how the in-plane Zeeman field and the Hubbard interaction can jointly affect the topological states in the Kane-Mele-Hubbard model. At low Zeeman field, the projecto…
Nonzero angular momentum density wave phases in SU() fermions with singlet-bond and triplet-current interactions
Han Xu, Congjun Wu, Yu Wang
We employ the sign-problem-free projector determinant quantum Monte Carlo method to study a microscopic model of SU() fermions with singlet-bond and triplet-current interactions…
Quantum Monte Carlo simulations of thermodynamic properties of attractive SU() Dirac fermions
Xiang Li, Han Xu, Yu Wang
We employ the determinant quantum Monte Carlo method to study the finite-temperature properties of the half-filled attractive SU() Hubbard model on a honeycomb lattice. We calcu…
Mott insulating states of the anisotropic SU(4) Dirac fermions
Han Xu, Yu Wang, Zhichao Zhou +1
We employ the large-scale quantum Monte-Carlo simulations to investigate the Mott-insulating states of the half-filled SU(4) Hubbard model on the square lattice with a staggered-fl…
Trion states and quantum criticality of attractive SU(3) Dirac fermions
Han Xu, Xiang Li, Zhichao Zhou +4
We perform the projector quantum Monte Carlo (QMC) simulation to study the trion formation and quantum phase transition in the half-filled attractive SU(3) Hubbard model on a honey…
Generalizable control for quantum parameter estimation through reinforcement learning
Han Xu, Junning Li, Liqiang Liu +3
Measurement and estimation of parameters are essential for science and engineering, where one of the main quests is to find systematic schemes that can achieve high precision. Whil…
