强耦合区无时间卷积非马尔可夫主方程

Time-convolutionless non-Markovian master equation in strong-coupling regime

Yang Li, Bin Luo, Jian-Wei Zhang, Hong Guo

摘要:

无时间卷积(TCL)非马尔可夫主方程由于其奇异性,一般认为在有限时刻崩溃,在强耦合区域不能产生渐近行为。然而,在本文中,我们表明,奇异性是不是TCL主方程的有效性的障碍。进一步,我们提出了一种多尺度微扰方法,该方法适用于强耦合区域的TCL主方程的求解,而普通的微扰方法在此区域是无效的。

英文摘要:

The time-convolutionless (TCL) non-Markovian master equation was generally thought to break down at finite time due to its singularity and fail to produce the asymptotic behavior in strong coupling regime. However, in this paper, we show that the singularity is not an obstacle for validity of the TCL master equation. Further, we propose a multiscale perturbative method valid for solving the TCL master equation in strong coupling regime, though the ordinary perturbative method invalidates therein.
