论文摘要
我们从数值上研究了在存在外部疾病的情况下，在二维大比塔维斯基晶状体中，最初限制状态的淬灭膨胀动力学。扩展动力学在能量和标准密度的控制参数空间中方便地描述。如果预期的最终状态是一种非抗病性，无论疾病的强度如何，这种扩展会大大减慢。同样，更强的障碍延迟了扩张。我们将结果与最近的量子研究进行比较。
We numerically investigate the quench expansion dynamics of an initially confined state in a two-dimensional Gross-Pitaevskii lattice in the presence of external disorder. The expansion dynamics is conveniently described in the control parameter space of the energy and norm densities. The expansion can slow down substantially if the expected final state is a non-ergodic non-Gibbs one, regardless of the disorder strength. Likewise stronger disorder delays expansion. We compare our results with recent studies for quantum many body quench experiments.
