开放量子系统动力学的后马尔可夫主方程

Post-Markov master equation for the dynamics of open quantum systems

Ting Yu, Lajos Diosi, Nicolas Gisin, Walter T. Strunz

摘要:

对玻色浴与开放量子系统相互作用的标准马尔可夫主方程提出了一个系统的一阶修正。它扩展了马尔可夫林德布拉德主方程的更一般的情况下,非马尔可夫演化。我们的“后”马尔可夫主方程的意义和应用进行了说明与几个例子,包括阻尼二能级原子,自旋玻色子模型和量子布朗运动模型。讨论了马尔可夫近似的局限性、正性破坏和初始滑移问题。

英文摘要:

A systematic first-order correction to the standard Markov master equation for open quantum systems interacting with a bosonic bath is presented. It extends the Markov Lindblad master equation to the more general case of non-Markovian evolution. The meaning and applications of our `post'-Markov master equation are illustrated with several examples, including a damped two-level atom, the spin-boson model and the quantum Brownian motion model. Limitations of the Markov approximation, the problem of positivity violation and initial slips are also discussed.
