Title: The Pseudomode Framework for Open Quantum Systems

Abstract: 

The pseudomode framework provides an exact description of the dynamics of an open quantum system coupled to a non-Markovian environment. Using this framework, the influence of the environment on the system is studied in an equivalent model, where the open system is coupled to a finite number of unphysical pseudomodes that follow a time-local master equation. We here discuss the most general conditions on the master equation that guarantee the correct reproduction of the system’s original dynamics. Further, we show that pseudomodes, despite their unphysical nature, provide a natural picture in which physical processes such as the creation of system-bath correlations or the exchange of heat can be studied.
