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

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 …

Classical thermodynamics is unrivalled in its range of applications and relevance to
everyday life. It enables a description of complex systems, made up of microscopic particles …

We study a quantum heat engine at strong coupling between the system and the thermal
reservoirs. Exploiting a collective coordinate mapping, we incorporate system-reservoir …

We study a minimal quantum Otto heat engine, where the working medium consists of an
interacting few-body system in a harmonic trap. This allows us to consider the interaction …

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 …

Theoretical treatments of periodically driven quantum thermal machines (PD-QTMs) are
largely focused on the limit-cycle stage of operation characterized by a periodic state of the …

We present a general unified approach for the study of quantum thermal machines,
including both heat engines and refrigerators, operating under periodic adiabatic driving …

We consider a finite-time Otto engine operating on a quantum harmonic oscillator and driven
by shortcut-to-adiabaticity (STA) techniques to speed up its cycle. We study its efficiency and …

We study the thermodynamic performance of a finite-time non-regenerative quantum Stirling-
like cycle used as a heat engine. We consider specifically the case in which the working …
