标题： Floquet realization of prethermal Meissner phase in a two-leg flux ladder

摘要： 我们证明，对于大的驱动幅度和特殊的驱动频率，一个周期性驱动的双链通量梯子上承载相互作用 hardcore 玻色子时会出现预热梅斯纳相。这种预热梅斯纳相由有限的时间平均手征电流表征。我们使用弗洛凯微扰理论找到了这些频率的解析表达式。我们的分析揭示，预热梅斯纳相的存在与这些驱动梯子中强希尔伯特空间碎片化的出现有关。我们通过精确对角化有限尺寸通量梯子的数值研究支持了我们的解析结果，并讨论了可能测试我们理论的超冷偶极原子平台实验。 显示英文摘要

摘要： We show that a periodically driven two-leg flux ladder hosting interacting hardcore bosons exhibits a prethermal Meissner phase for large drive amplitudes and at special drive frequencies. Such a prethermal Meissner phase is characterized by a finite time-averaged chiral current. We find an analytic expression of these frequencies using Floquet perturbation theory. Our analysis reveals that the presence of the prethermal Meissner phase is tied to the emergence of strong Hilbert space fragmentation in these driven ladders. We support our analytical results by numerical study of finite-size flux ladders using exact diagonalization and discuss experiments using ultracold dipolar atom platforms that may test our theory.
