Quantum and Information Thermodynamics: A Unifying Framework based on Repeated Interactions — •Philipp Strasberg1,2, Gernot Schaller1, Tobias Brandes1, and Massimiliano Esposito2 — 1Institut für Theoretische Physik, Technische Universität Berlin, Hardenbergstr. 36, D-10623 Berlin, Germany — 2Complex Systems and Statistical Mechanics, Physics and Materials Science, University of Luxembourg, L-1511 Luxembourg, Luxembourg
We expand the standard thermodynamic framework of a system coupled to a thermal reservoir by considering a stream of independently prepared units repeatedly put into contact with the system. These units can be in any nonequilibrium state and interact with the system with an arbitrary strength and duration. We show that this stream constitutes an effective resource of nonequilibrium free energy and unifies many previously separately studied phenomena. This includes, e.g., work and information reservoirs, Landauer's principle, Maxwell's demon, the micromaser, extraction of work from quantum coherence and much more. Some of these (but not all) applications are presented in the talk.
