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 …

We study fluctuations in many-body quantum heat engines operating in the presence of
collective system-bath interactions. We show that collective effects in open quantum systems …

Recent predictions for quantum-mechanical enhancements in the operation of small heat
engines have raised renewed interest in their study both from a fundamental perspective …

Do quantum correlations lead to better performance with respect to several different systems
working independently? For quantum thermal machines, the question is whether a working …

Quantum systems of indistinguishable particles are commonly described using the
formalism of second quantization, which relies on the assumption that any admissible …

We start with a revision study of two coupled spin-1/2 under the influence of Kaplan–
Shekhtman–Entin-Wohlman–Aharony interaction and a magnetic field. We first show the …

Cooperative effects of multiple quantum emitters are characterized by transitions via
delocalized collective states with altered emission properties due to the existence of …

Quantum thermodynamics explores novel thermodynamic phenomena that emerge when
interactions between macroscopic systems and microscopic quantum ones go into action …

We introduce a class of stochastic engines in which the regime of units operating
synchronously can boost the performance. Our approach encompasses a minimal setup …

Superposition of trajectories, which modify quantum evolutions by superposing paths
through interferometry, has been utilized to enhance various quantum communication tasks …
