Quantum magnetic properties of the SU(2N) Hubbard model in the square lattice: a quantum Monte Carlo study
Zi Cai, Hsiang-Hsuan Hung, Lei Wang +1
We employ the determinant projector quantum Monte-Carlo method to investigate the ground state magnetic properties in the Mott insulating states of the half-filled SU(4) and SU(6)…
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…
Magnetic phases of bosons with synthetic spin-orbit coupling in optical lattices
Zi Cai, Xiangfa Zhou, Congjun Wu
We investigate magnetic properties in the superfluid and Mott-insulating states of two-component bosons with spin-orbit (SO) coupling in 2D square optical lattices. The spin-indepe…
Pomeranchuk cooling of the SU() ultra-cold fermions in optical lattices
Zi Cai, Hsiang-hsuan Hung, Lei Wang +2
We investigate the thermodynamic properties of a half-filled SU(2N) Fermi-Hubbard model in the two-dimensional square lattice using the determinantal quantum Monte Carlo simulation…
