我们调查开车的地怎么与杂质在一个维的二粒子的 Bose-Hubbard 模型影响界限状态。在高周波的政体,与静态的格子相比[Phys。加快。Lett。109 (2012 ) 116405 ] , Floquet 界限状态的一种新类型能被调节开车振幅甚至为一个弱粒子粒子相互作用获得。而且, Floquet 的本地化度跳了分子的状态能被调节开车频率调整,并且甚至 Floquet 跳了分子的状态能被变成 Floquet 当开车频率在批评价值下面时,扩大了状态。我们的结果提供一个有效方法在许多身体系统操作界限状态。
We investigate how the driving field affects the bound states in the one-dimensional two-particle Bose-Hubbard model with an impurity. In the high-frequency regime, compared with the static lattice [Phys. Rev. Lett. 109 (2012) 116405], a new type of Floquet bound state can be obtained even for a weak particle-particle interaction by tuning the driving amplitude. Moreover, the localization degree of the F1oquet bound molecular state can be adjusted by tuning the driving frequency, and even the Floquet bound molecular state can be changed into the Floquet extended state when the driving frequency is below a critical value. Our results provide an efficient way to manipulate bound states in the many-body systems.
