论文摘要
我们研究了在线性增加场的应用下，相互作用的量子自旋链的动力学。该模型表现出一种被称为Stark多体定位的定位。动力学表明对初始条件的依赖性很强，表明该系统违反了该领域任何有限梯度的常规（“强”）特征态热假设。这与数值观察到的厄乳相的报道相反。因此，该定位与无序驱动的多体定位至关重要，这与最近通过希尔伯特空间粉碎的定位进行预测一致。
We study the dynamics of an interacting quantum spin chain under the application of a linearly increasing field. This model exhibits a type of localization known as Stark many-body localization. The dynamics shows a strong dependence on the initial conditions, indicating that the system violates the conventional ("strong") eigenstate thermalization hypothesis at any finite gradient of the field. This is contrary to reports of a numerically observed ergodic phase. Therefore, the localization is crucially distinct from disorder-driven many-body localization, in agreement with recent predictions on the basis of localization via Hilbert-space shattering.
