Information free energy for nonequilibrium states — Sebastian Deffner1 and •Eric Lutz2 — 1Department of Chemistry and Biochemistry, University of Maryland, College Park, MD 20742 — 2Dahlem Center for Complex Quantum Systems, Freie Universität Berlin, 14195 Berlin
We introduce an information free energy for thermodynamic systems driven by external time-dependent parameters. We show that the latter is a nonequilibrium state function and that it is a natural generalization of the usual equilibrium free energy. We discuss its importance for the maximum work theorem, the Jarzynski relation in the presence of feedback, and the relaxation to nonequilibrium steady states.
