Rare events and scaling properties in field-induced anomalous dynamics
R. Burioni, G. Gradenigo, A. Sarracino +2
We show that, in a broad class of continuous time random walks (CTRW), a small external field can turn diffusion from standard into anomalous. We illustrate our findings in a CTRW…
Brownian ratchet in a thermal bath driven by Coulomb friction
A. Gnoli, A. Petri, F. Dalton +4
The rectification of unbiased fluctuations, also known as the ratchet effect, is normally obtained under statistical non-equilibrium conditions. Here we propose a new ratchet mecha…
Static correlations functions and domain walls in glass-forming liquids: the case of a sandwich geometry
G. Gradenigo, R. Trozzo, A. Cavagna +2
The problem of measuring nontrivial static correlations in deeply supercooled liquids made recently some progress thanks to the introduction of amorphous boundary conditions, in wh…
Einstein relation in superdiffusive systems
Giacomo Gradenigo, Alessandro Sarracino, Dario Villamaina +1
We study the Einstein relation between diffusion and response to an external field in systems showing superdiffusion. In particular, we investigate a continuous time Levy walk wher…
Entropy production in non-equilibrium fluctuating hydrodynamics
Giacomo Gradenigo, Andrea Puglisi, Alessandro Sarracino
Fluctuating entropy production is studied for a set of linearly coupled complex fields. The general result is applied to non-equilibrium fluctuating hydrodynamic equations for coar…
Out-of-equilibrium generalized fluctuation-dissipation relations
Giacomo Gradenigo, Andrea Puglisi, Alessandro Sarracino +2
We discuss fluctuation-dissipation relations valid under general conditions even out of equilibrium. The response function is expressed in terms of unperperturbed correlation funct…
Dynamics of a massive intruder in a homogeneously driven granular fluid
A. Puglisi, A. Sarracino, G. Gradenigo +1
A massive intruder in a homogeneously driven granular fluid, in dilute configurations, performs a memory-less Brownian motion with drag and temperature simply related to the averag…
