When a system is perturbed by the variation of external parameters, a lag generally develops between the actual state of the system, ρt, and the equilibrium state corresponding to the current parameter values, ρteq. We establish a microscopic, quantitative relation between this lag and the dissipated work that accompanies the process. We illustrate this relation using a model system.

Near-optimal protocols in complex nonequilibrium transformations (2016, background): “There is a natural connection between dissipation and lag (41, 42): the farther the system falls out of equilibrium with control parameters’ instantaneous values, the more heat is dissipated to the reservoir during the relaxation.”
Experiments in Stochastic Thermodynamics: Short History and Perspectives (2017, methodology): “This connection is reenforced by the relationship between the generalized Jarzinsky equality [154] and the Landauer bound, which has been proved and tested on experimental data in Ref.”
Stochastic thermodynamics, fluctuation theorems and molecular machines (2012, methodology): “which bounds dissipation by the distinguishability of the instantaneous distribution with the corresponding equilibrium distribution as derived and discussed in [270].”
