无序光晶格中相互作用玻色子的受控局域化
Controlled localization of interacting bosons in a disordered optical lattice
摘要:
研究表明,即使在无序的情况下,光晶格中相互作用的超冷原子的隧穿和局域化性质也可以通过控制快速振荡力来控制。我们的计算是基于时间相关的薛定谔方程的精确解,使用Floquet形式主义。我们的研究结果的影响,更大的系统和控制无序相互作用玻色子系统的相图的可能性进行了讨论。
英文摘要:
We show that tunneling and localization properties of interacting ultracold atoms in an optical lattice can be controlled by adiabatically turning on a fast oscillatory force even in the presence of disorder. Our calculations are based on the exact solution of the time-dependent Schroedinger equation, using the Floquet formalism. Implications of our findings for larger systems and the possibility of controlling the phase diagram of disordered-interacting bosonic systems are discussed.
