在吝啬地的三地点的 BoseHubbard 模型以内,偶极的 bosonic 气体与的通道动力学一周期性地,散布的 s 波浪的调整被调查。系统经历通道(CDT ) 的协调破坏转移在下邻居偶极子偶极子相互作用,所在地的相互作用和散布的调制 s 波浪之中源于相关效果的复杂、富有的协调通道(CT ) 。特别地,为产生 CT (CDT ) 散布的调制 s 波浪的区域是最宽(最狭窄) 什么时候所在地的相互作用和下邻居偶极子偶极子相互作用一些相关与通道精力和系统的相互作用精力有关仔细珍视,它是。为出现 CDT 的相关的值能理论上从通道精力和系统的相互作用精力被获得。
Within the mean-field three-site Bose-Hubbard model, the tunneling dynamics of dipolar bosonic gas with a periodically modulation of s-wave scattering is investigated. The system experiences complex and rich coherent tunneling (CT)-coherent destruction of tunneling (CDT) transitions resulting from the correlated effect among the next-neighbor dipole-dipole interaction, the on-site interaction and the modulated s-wave scattering. In particular, The region of the modulated s-wave scattering for generating CT (CDT) is the widest (narrowest) when the on-site interaction and the next-neighbor dipole-dipole interaction have some correlated values, which are closely related to the tunneling energy and the interaction energy of the system. The correlated values for appearing CDT can be theoreticaJly gained from the tunneling energy and the interaction energy of the system.
