Thermodynamics with Continuous Information Flow — •Massimiliano Esposito — University of Luxembourg, 162a avenue de la Faïencerie, L-1511 Luxembourg, Luxembourg.

A unified thermodynamic formalism describing information transfers in autonomous as well as nonautonomous systems described by stochastic thermodynamics will be presented. Information is continuously generated in an auxiliary system and then transferred to a relevant system that can utilize it to fuel otherwise impossible processes. Indeed, while the joint system satisfies the second law, the entropy balance for the relevant system is modified by an information term related to the mutual information rate between the two systems. This formalism will be applied to various model systems, including an electronic Maxwell demon.
