摘要:

我们提供了一个一般性的讨论Liouvillian频谱耦合到一个非马尔可夫浴用Floquet理论的系统。这种方法是合适的,当系统描述的时间卷积主方程的时间周期率。令人惊讶的是,速率的周期性使我们能够在离散时间拥有频闪可分的动力学映射,我们称之为Floquet频闪可分性。我们说明了薛定谔猫漫游在一个非马尔可夫浴的一般理论,并证明了频闪复苏的猫在其死亡后的晚些时候出现。我们的理论可能对非平衡系统中的熵产生有深远的影响。

英文摘要:

We provide a general discussion of the Liouvillian spectrum for a system coupled to a non-Markovian bath using Floquet theory. This approach is suitable when the system is described by a time-convolutionless master equation with time-periodic rates. Surprisingly, the periodic nature of rates allow us to have a stroboscopic divisible dynamical map at discrete times, which we refer to as Floquet stroboscopic divisibility. We illustrate the general theory for a Schrödinger cat which is roaming inside a non-Markovian bath, and demonstrate the appearance of stroboscopic revival of the cat at later time after its death. Our theory may have profound implications in entropy production in non-equilibrium systems.
