Quantum Phases of Bose-Hubbard Model in Optical Superlattices
Bo-Lun Chen, Su-Peng Kou, Yunbo Zhang +1
In this paper, we analyze the quantum phases of multiple component Bose-Hubbard model in optical superlattices, using a mean-field method, the decoupling approximation. We find tha…

Emergence of Topological Fermi Liquid from a Strongly Correlated Bosonic System in Optical Superlattices
Bo-lun Chen, Su-peng Kou
Recent experiments on quantum degenerate gases give an opportunity for simulating strongly-correlated electronic systems in optical lattices. It may shed light on some long-standin…

Mott-Hubbard Transition of Bosons in Optical Lattices with Three-body Interactions
Bo-Lun Chen, Xiao-Bin Huang, Su-Peng Kou +1
In this paper, the quantum phase transition between superfluid state and Mott-insulator state is studied based on an extended Bose-Hubbard model with two- and three-body on-site in…
