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…
Mott transition in the -flux SU() Hubbard model on a square lattice
Zhichao Zhou, Congjun Wu, Yu Wang
We employ the projector quantum Monte Carlo simulations to study the ground-state properties of the square-lattice SU(4) Hubbard model with a flux per plaquette. In the weak co…
Finite-temperature valence-bond-solid transitions and thermodynamic properties of interacting SU() Dirac fermions
Zhichao Zhou, Da Wang, Congjun Wu +1
We investigate the SU() symmetry effects with on the two-dimensional interacting Dirac fermions at finite temperatures, including the valence-bond-solid transition, the…
Mott insulating states and quantum phase transitions of correlated SU(2N) Dirac fermions
Zhichao Zhou, Da Wang, Zi Yang Meng +2
The interplay between charge and spin degrees of freedom in strongly correlated fermionic systems, in particular of Dirac fermions, is a long-standing problem in condensed matter p…
Quantum Monte Carlo simulation of thermodynamic properties of SU(2N) ultracold fermions in optical lattices
Zhichao Zhou, Zi Cai, Congjun Wu +1
We have systematically studied the thermodynamic properties of a two-dimensional half-filled SU(2N) Hubbard model on a square lattice by using the determinant quantum Monte Carlo m…
Frustrated Bose-Einstein condensates with non-collinear orbital ordering
Zi Cai, Yu Wang, Congjun Wu
We investigate the unconventional Bose-Einstein condensations (BEC) with the orbital degree of freedom in the 3D cubic optical lattice, which give rise to various exotic features a…
