[en] 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 we
identify the conditions under which it behaves as a heat, work, or information reservoir. We also show that
this setup provides a natural framework to analyze information erasure (“Landauer’s principle”) and
feedback-controlled systems (“Maxwell’s demon”). In the limit of a short system-unit interaction time, we
further demonstrate that this setup can be used to provide a thermodynamically sound interpretation to
many effective master equations. We discuss how nonautonomously driven systems, micromasers, lasing
without inversion and the electronic Maxwell demon can be thermodynamically analyzed within our
framework. While the present framework accounts for quantum features (e.g., squeezing, entanglement,
coherence), we also show that quantum resources do not offer any advantage compared to classical ones in
terms of the maximum extractable work.
