摘　　要：利用碰撞模型研究系统与环境具有初始量子关联时,库里有无关联对开放量子系统动力学行为的影响.将环境分成两部分,一部分是能与系统直接相互作用的,称作内部环境;另一部分是不与系统直接相互作用的,称作剩余环境,也就是所说的库.研究发现,两种情形均表明在环境和系统之间存在初始量子关联时,都能引起系统的非马尔科夫现象,并且相同条件下,改变系统和环境的相互作用强度,库里有无关联也会对系统的非马尔科夫性产生明显不同的影响.Investigated the influence of having or not having correlation in the bank on the dynamical behavior of open quantum systems based on a collision model, when existing initial quantum correlation between system and environment. The environment is divided into two parts, one part can interact with system directly, which is called internal environment, and another part can not directly interact with the environment, which is called remain environment, that is what we call bank. It is found that it can lead the non-Markovian dynamics in both cases, when the initial quantum correlation between the system and the environment exists. And, under the same conditions, for different interaction strength between the system and environment, non-Markovian also will be significantly different between the remain environments with or without correlation.
