Ginzburg-Landau effective action approach to disordered Bose-Hubbard Model
Botao Wang, Ying Jiang
We study the phase transition from Mott insulator (MI) to Bose glass (BG) of a disordered Bose-Hubbard model within the framework of Ginzburg-Landau effective action approach. By t…
Quantum Phase diagram and time-of-flight absorption pictures of ultracold Bose system in a square optical superlattice
Fan Wei, Jun Zhang, Ying Jiang
In this letter, by the use of the generalized effective potential theory, with the help of process-chain approach under the framework of Kato formulation of perturbation expansion,…
Bogoliubov approach to superfluid-Bose glass phase transition of a disordered Bose-Hubbard Model in weakly interacting regime
Botao Wang, Ying Jiang
We investigate the disorder effect on coherent fraction and the quantum phase transition of ultracold dilute Bose gases trapped in disordered optical lattices. Within the framework…
Visibility of ultra-cold Bose system in triangular optical lattices
Zhi Lin, Jun Zhang, Ying Jiang
In this paper, by treating the hopping parameter in Bose-Hubbard model as a perturbation, with the help of the re-summed Green's function method and cumulants expansion, the moment…
