Abstract:
Open quantum systems (OQS) cannot always be described with the Markov approximation, which requires a large separation of system and environment time scales. In this talk I will give an overview of some recent advances to tackle the dynamics of an OQS beyond the Markov approximation, with special emphasis in hierarchy-based [1,2] and chain mapping-based [3] approaches. In the latter context, I will discuss the use of a thermofield transformation to describe thermal environments [4].
