In this work we study the reduced dynamics of a system embedded in a quantum environment, with the use of correlation functions produced through appropriately defined reduced generating functionals. Our construction is based on expressing these functionals in terms of consistently defined coherent-state path integrals in the framework of the Keldysh-Schwinger out-of-equilibrium formalism.

开放玻色子和费米子系统中的降低动力学

在这项工作中，我们研究了嵌入量子环境中的系统的简化动力学，并使用了通过适当定义的简化生成泛函产生的相关函数。我们的构建基于在 Keldysh-Schwinger 失衡形式主义的框架中根据一致定义的相干状态路径积分来表达这些泛函。
