Simulating quantum mechanics is known to be a difficult computational problem, especially
when dealing with large systems. However, this difficulty may be overcome by using some …

In recent years, the study of heat to work conversion has been re-invigorated by
nanotechnology. Steady-state devices do this conversion without any macroscopic moving …

Quantum thermodynamics is an emerging research field aiming to extend standard
thermodynamics and non-equilibrium statistical physics to ensembles of sizes well below …

Heat engines convert thermal energy into mechanical work and generally involve a large
number of particles. We report the experimental realization of a single-atom heat engine. An …

Thermodynamics originated in the need to understand novel technologies developed by the
Industrial Revolution. However, over the centuries, the description of engines, refrigerators …

Quantum thermodynamics addresses the emergence of thermodynamic laws from quantum
mechanics. The viewpoint advocated is based on the intimate connection of quantum …

We consider a quantum Otto cycle for a time-dependent harmonic oscillator coupled to a
squeezed thermal reservoir. We show that the efficiency at maximum power increases with …

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

Quantum heat engines (QHE) are thermal machines where the working substance is a
quantum object. In the extreme case, the working medium can be a single particle or a few …

A quantum thermal machine is an open quantum system coupled to hot and cold thermal
baths. Thus, its dynamics can be well understood using the concepts and tools from non …
