We study the power extracted by an electromagnetic energy harvester driven by broadband vibrations. We describe the system with a linear model, featuring an underdamped stochastic differential equation for an effective mass in a harmonic potential, c

We experimentally study a piezoelectric energy harvester driven by broadband random vibrations. We show that a linear model, consisting of an underdamped Langevin equation for the dynamics of the tip mass, electromechanically coupled with a capacitor

We consider work extraction from N copies of a quantum system. When the same work-extraction process is implemented on each copy, the relative size of fluctuations is expected to decay as $1/\sqrt{N}$ . Here, we consider protocols where the copies ca

We study the problem of the energetic cost of information erasure by looking at it through the lens of the Jarzynski equality. We observe that the Landauer bound, ? W? >= kTln 2 , on average dissipated work ? W? associated to an erasure process, lite

In a ‘shortcut to adiabaticity’ (STA) protocol, the counter-diabatic Hamiltonian, which suppresses the non-adiabatic transition of a reference ‘adiabatic’ trajectory, induces a quantum uncertainty of the work cost in the framework of quantum

We experimentally investigate the non-equilibrium steady-state distribution of the work done by an external force on a mesoscopic system with many coupled degrees of freedom: a colloidal crystal mechanically driven across a commensurate periodic ligh
