论文摘要
最近的实验表明，偶极系统的周期性驱动器会导致长期寿命的pr虫状态。这些系统与环境弱耦合，并在时间尺度上到达pr虫的状态，比热化的时间尺度要短得多。以前已经使用Floquet形式主义对这种几乎关闭的系统进行了分析，该系统表明了高原高原的出现。我们使用波动调节的量子主方程（FRQME）来描述这些系统。除了系统环境耦合外，FRQME还成功地捕获了系统中各种局部相互作用的耗散效应。我们的调查显示，该系统的旅程是最终的稳定状态。级联反应涉及一组以准固定量为特征的预先逮捕状态。我们表明，这些prether虫在时间尺度上出现的时间比放松时间范围短得多。我们还发现并报告了临界限制的存在，超越了高原高原的存在。
Recent experiments show that periodic drives on dipolar systems lead to long-lived prethermal states. These systems are weakly coupled to the environment and reach prethermal states in a timescale much shorter than the timescale for thermalization. Such nearly-closed systems have previously been analyzed using Floquet formalism, which shows the emergence of a prethermal plateau. We use a fluctuation-regulated quantum master equation (FRQME) to describe these systems. In addition to the system-environment coupling, FRQME successfully captures the dissipative effect from the various local interactions in the system. Our investigation reveals a cascaded journey of the system to a final steady state. The cascade involves a set of prethermal or arrested states characterized by a set of quasi-conserved quantities. We show that these prethermal states emerge in a timescale much shorter than the relaxation timescale. We also find and report the existence of a critical limit beyond which the prethermal plateau ceases to exist.
