论文摘要
我们提出了通用开放量子系统正式精确的主方程的简洁而直观的推导，而无需使用“逆”映射，该图在以前的正式精确主方程上所调用。这种形式主义适用于非马克维亚政权。我们在任意温度下得出了说明性自旋 - 玻色子模型的二阶运动方程，观察到非指数的反谐和和松弛。将我们的通用推导限制为零温度，我们还为物理中真空浴的特殊情况重现了结果。修订版A 81，042103（2010）。
We present a succinct and intuitive derivation of a formally exact master equation for general open quantum systems, without the use of an "inverse" map which was invoked in previous works on formally exact master equations. This formalism is applicable to non-Markovian regimes. We derive a second-order equation of motion for the illustrative spin-boson model at arbitrary temperatures, observing non-exponential decoherence and relaxation. Limiting our generic derivation to zero temperature, we also reproduce the result for the special case of a vacuum bath in Phys. Rev. A 81, 042103 (2010).
