The seminal work by Sadi Carnot in the early nineteenth century provided the blueprint of a
reversible heat engine and the celebrated second law of thermodynamics eventually …

Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

Quantum heat engines are subjected to quantum fluctuations related to their discrete energy
spectra. Such fluctuations question the reliable operation of thermal machines in the …

The pseudomode framework provides an exact description of the dynamics of an open
quantum system coupled to a non-Markovian environment. Using this framework, the …

A general thermodynamic framework is presented for open quantum systems in fixed contact
with a thermal reservoir. The first and second law are obtained for arbitrary system-reservoir …

We consider a finite-time quantum Otto cycle with single-and two spin-1/2 systems as its
working medium. To mimic adiabatic dynamics at a finite time, we employ a shortcut-to …

Entropy production plays a fundamental role in nonequilibrium thermodynamics to quantify
the irreversibility of open systems. Its positivity can be ensured for a wide class of setups, but …

The thermodynamic framework of repeated interactions is generalized to an arbitrary open
quantum system in contact with a heat bath. Based on these findings, the theory is then …

It is investigated whether non-Markovianity, ie, the memory effects resulting from the
coupling of the system to its environment, can be beneficial for the performance of quantum …

We demonstrate how to incorporate a catalyst to enhance the performance of a heat engine.
Specifically, we analyze efficiency in one of the simplest engine models, which operates in …
