论文摘要
我们通过考虑浴室的显微镜模型，即，在参数区域中的玻色 - 哈伯德链，在量子混乱的意义上，它是混乱的，我们通过考虑浴室的微观模型来重新审视开放量子系统的Born-Markov近似。结果表明，浴室的强颈特性证明了从第一原理中得出马尔可维亚主方程所需的所有近似值。
We revisit the Born-Markov approximation for an open quantum system by considering a microscopic model of the bath, namely, the Bose-Hubbard chain in the parameter region where it is chaotic in the sense of Quantum Chaos. It is shown that strong ergodic properties of the bath justify all approximations required for deriving the Markovian master equation from the first principles.
