Entropy production is a key quantity in any finite-time thermodynamic process. It is intimately
tied with the fundamental laws of thermodynamics, embodying a tool to extend …

Developments in the thermodynamics of small quantum systems envisage nonclassical
thermal machines. In this scenario, energy fluctuations play a relevant role in the description …

Insights into complex phenomena in quantum matter can be gained from simulation
experiments with ultracold atoms, especially in cases where theoretical characterization is …

The working substance fueling a quantum heat engine may contain coherence in its energy
basis, depending on the dynamics of the engine cycle. In some models of quantum Otto heat …

Heat spontaneously flows from hot to cold in standard thermodynamics. However, the latter
theory presupposes the absence of initial correlations between interacting systems. We here …

Quantum thermodynamics seeks to extend non-equilibrium stochastic thermodynamics to
small quantum systems where non-classical features are essential to its description. Such a …

This article sets up a new formalism to investigate stochastic thermodynamics in the
quantum regime, where stochasticity and irreversibility primarily come from quantum …

We use continuous weak measurements of a driven superconducting qubit to experimentally
study the information dynamics of a quantum Maxwell's demon. We show how information …

Maxwell's demon explores the role of information in physical processes. Employing
information about microscopic degrees of freedom, this “intelligent observer” is capable of …

Exploiting the relative entropy of coherence, we isolate the coherent contribution in the
energetics of a driven nonequilibrium quantum system. We prove that a division of the …
