Atom-pair tunneling and quantum phase transition in asymmetry double-well trap in strong-interaction regime
《Chinese Physics B》2019年第11期67-73,共7页Ji-Li Liu Jiu-Qing Liang 
Project supported by the National Natural Science Foundation of China(Grant No.11075099)
The quantum effect of nonlinear co-tunnelling process, which is dependent on atom-pair tunneling and asymmetry of an double-well trap, is studied by using an asymmetrical extended Bose–Hubbard model. Due to the exist...
