Reduced Dynamics in Open Bosonic and Fermionic Systems
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.
期刊介绍：
The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication, filtering, memory and cooperative behaviour, etc., in open complex systems.
