论文摘要
我们讨论定期驱动的开放量子系统的动态。量子状态的时间演变由量子主方程描述，并选择散射器的形式，以便通过Gibbs分布给出瞬时固定态。我们发现，人口部分与密度运算符的相干部分之间的相关性是由绝热规格电位引起的。尽管引入抵绝热项消除了相关性，但其他相关性阻止了与吉布斯分布的收敛。我们通过抵绝热期限研究控制的性能。该系统具有三个不同的量表，性能很大程度上取决于它们的幅度之间的关系。
We discuss dynamics of periodically-driven open quantum systems. The time evolution of the quantum state is described by the quantum master equation and the form of the dissipator is chosen so that the instantaneous stationary state is given by the Gibbs distribution. We find that the correlation between the population part and the coherence part of the density operator is induced by an adiabatic gauge potential. Although the introduction of the counterdiabatic term eliminates the correlation, additional correlations prevent a convergence to the Gibbs distribution. We study the performance of the control by the counterdiabatic term. The system has three different scales and the performance strongly depends on the relations among their magnitudes.
