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…
Two-orbital model for possible superconductivity pairing mechanism in nickelates
Chen Lu, Lun-Hui Hu, Yu Wang +2
The newly synthesized strontium doped RNiO (R=Nd, La) superconductors have stimulated extensive interests in understanding their pairing mechanism and pairing nature. Here we s…
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…

Detecting edge degeneracy in interacting topological insulators through entanglement entropy
Da Wang, Shenglong Xu, Yu Wang +1
The existence of degenerate or gapless edge states is a characteristic feature of topological insulators, but is difficult to detect in the presence of interactons. We propose a ne…

We non-perturbatively investigate the ground state magnetic properties of the 2D half-filled SU() Hubbard model in the square lattice by using the projector determinant quantum…
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…
