Obtaining dynamics of an interacting quantum many-body system connected to multiple baths initially at different, finite, temperatures and chemical potentials is a challenging problem. This is due to a combination of the prevalence of strong correlations in the system, the infinite nature of the baths and the long time to reach steady state. In this work we develop a general formalism that allows access to the full non-Markovian dynamics of such open quantum many-body systems up to the non…

Signatures of Liouvillian Exceptional Points in a Quantum Thermal Machine
Viewing a quantum thermal machine as a non-Hermitian quantum system, we characterize in full generality its analytical time-dependent dynamics by deriving the spectrum of its non-Hermitian

TLDR
This Perspective paper focuses on collision models, which have emerged as a remarkably flexible approach to understanding non-Markovian dynamics and to studying the thermodynamics of quantum systems, two areas in which they have proven to be particularly insightful.
