Non-Markovianity, entropy production, and Jarzynski equality

We explore the role a non-Markovian memory kernel plays on information exchange and entropy production in context of external work protocol. The Jarzynski equality is shown to hold for both harmonic nonharmonic models. observe function acts as an pump, recovering part lost thermal reservoir consequence nonequilibrium pumping action occurs cases. Unexpectedly, we found that model does not produce entropy, regardless presence even small amount nonlinearity recovers more normal producing behavior, out-of-equilibrium protocols.
