Time asymmetry of the Kramers equation with nonlinear friction: fluctuation-dissipation relation and ratchet effect
A. Sarracino
We show by numerical simulations that the presence of nonlinear velocity-dependent friction forces can induce a finite net drift in the stochastic motion of a particle in contact w…
Ratchet effect driven by Coulomb friction: the asymmetric Rayleigh piston
A. Sarracino, A. Gnoli, A. Puglisi
The effect of Coulomb friction is studied in the framework of collisional ratchets. It turns out that the average drift of these devices can be expressed as the combination of a te…
Non-equilibrium fluctuations in frictional granular motor: experiments and kinetic theory
Andrea Gnoli, Alessandro Sarracino, Alberto Petri +1
We report the study of a new experimental granular Brownian motor, inspired to the one published in [Phys. Rev. Lett. 104, 248001 (2010)], but different in some ingredients. As in…
Fluctuation relations without uniform large deviations
Giacomo Gradenigo, Alessandro Sarracino, Andrea Puglisi +1
We study the fluctuations of a stochastic Maxwell-Lorentz particle model driven by an external field to determine the extent to which fluctuation relations are related to large dev…
