论文摘要
我们考虑一个微观碰撞模型，即量子系统与由辅助系统和储层组成的层次环境相互作用。我们展示了系统的非马克维亚特征如何受系统辅助系统和辅助系统 - 储存，初始系统 - 环境相关性和环境相干性的影响。然后，我们通过研究系统的熵变化，尤其是从具有记忆效应的热交换器来研究非马克维亚性与热力学特性之间的关系，我们揭示了非马克维亚进化过程中正值和负值之间熵变化的本质是由于连贯性确定的热通量的贡献。系统和环境之间的信息流总是伴随着能量交换。
We consider a microscopic collision model, i.e., a quantum system interacts with a hierarchical environment consisting of an auxiliary system and a reservoir. We show how the non-Markovian character of the system is influenced by the coupling strength of system-auxiliary system and auxiliary system-reservoir, initial system-environment correlations and the coherence of environment. Then we study the relation between non-Markovianity and thermodynamics properties, by studying the entropy change of system especially that from heat exchanges with memory effects, and we reveal the essence of entropy change between positive and negative values during non-Markovian evolution is due to the contribution of heat flux determined by coherence. And the information flow between the system and environment is always accompanied by energy exchange.
