论文摘要
我们应用了不均匀的木瓜 - Zurek机制的理论，以了解从莫特绝缘子到二维光学晶格和谐波陷阱的冷bose气体中从莫特绝缘体到超流体的动力学。与非绝热跃迁相关的局部淬火时间和冻结区域由于玻色 - 哈伯德模型的基态相图的Mott-Lobe结构而具有非平凡的位置依赖性。我们证明了通过时间依赖性的Gutzwiller模拟的淬灭动力学，揭示了超氟阶参数生长的不均匀特性。不均匀的千禧kurek理论适用于浅谐波陷阱。
We apply the theory of inhomogeneous Kibble-Zurek mechanism to understand quench dynamics from the Mott insulator to the superfluid in a cold Bose gases confined in both a two-dimensional optical lattice and a harmonic trap. The local quench time and the freeze-out region associated with the nonadiabatic transition take a nontrivial positional dependence due to the Mott-lobe structure of the ground state phase diagram of the Bose-Hubbard model. We demonstrate that the quench dynamics through the time-dependent Gutzwiller simulations, revealing inhomogeneous properties of the growth of the superfluid order parameter. The inhomogeneous Kibble-Zurek theory is applicable for the shallow harmonic trap.
