The statistical mechanical description of small systems staying in thermal equilibrium with an
environment can be achieved by means of the Hamiltonian of mean force. In contrast to the …

We propose a definition of externally measurable quantum work in driven systems. Work is
given as a quantum observable on a control device which is forcing the system and can be …

In this work, we present an analytical study of a linear kinetic energy harvester driven by
Gaussian noise through a nonequilibrium potential (NEP) approach. Taking advantage of …

We study the statistics of energy fluctuations in a three-level quantum system subject to a
sequence of projective quantum measurements. We check that, as expected, the quantum …

A result of great theoretical and experimental interest, the Jarzynski equality predicts a free
energy change Δ F of a system at inverse temperature β from an ensemble average of …

It has been established that the inclusive work for classical, Hamiltonian dynamics is
equivalent to the two-time energy measurement paradigm in isolated quantum systems …

The classical Jarzynski equality establishes an exact relation between the stochastic work
performed on a system driven out of thermal equilibrium and the free energy difference in a …

Abstract (EN) Work is one of the cornerstones of classical thermodynamics. However, a
direct transfer of this concept to quantum systems has proved problematic, especially for non …

A main problem, which is met when computing the energy transfer of or work done by a
quantum system, comes from the fact that the system may lie in states with coherence in its …

Jarzynski equality (JE) establishes a link between an equilibrium quantity, the free energy
change∆ F of a system at inverse temperature 1/kT and the ensemble average of non …
