论文摘要
在Floquet工程中，定期驾驶用于实现在热平衡中无法访问的物质的新阶段。为此，Floquet理论为我们提供了获得静态有效哈密顿量的秘诀。尽管许多现有作品已经处理过封闭的系统，但重要的是考虑耗散的效果，这本质上是无处不在的。了解周期性驾驶和耗散的相互作用不仅是非平衡统计物理学的基本问题，而且还引起了人们的兴趣，因为实验进步使我们能够以可控制的方式进行耗散。在这篇综述中，我们对开放式浮标系统的量子主程式的形式主义进行了详细的说明，并强调了最近的作品调查了均衡统计力学是否适用于浮球状态。
In Floquet engineering, periodic driving is used to realize novel phases of matter which are inaccessible in thermal equilibrium. For this purpose, the Floquet theory provides us a recipe of obtaining a static effective Hamiltonian. Although many existing works have treated closed systems, it is important to consider the effect of dissipation, which is ubiquitous in nature. Understanding interplay of periodic driving and dissipation is not only a fundamental problem of nonequilibrium statistical physics, but also receiving growing interest because of the fact that experimental advances have allowed us to engineer dissipation in a controllable manner. In this review, we give a detailed exposition on the formalism of quantum master equations for open Floquet systems and highlight recent works investigating whether equilibrium statistical mechanics applies to Floquet states.
