基于一个精确的非马尔可夫开放系统量子动力学,我们演示了如何通过驱动和耗散的协同效应来减小开放系统的熵。我们用Wigner函数说明了相空间中的受控动力学,并讨论了使用主方程近似方法的适用性。
Based on an exact non-Markovian open systems quantum dynamics, we demonstrate how to reduce the entropy of an open system through a cooperative effect of driving and dissipation. We illustrate the controlled dynamics in phase space in terms of Wigner functions and discuss the applicability of approximate approaches using master equations.
