Fluctuation-Dissipation relation in sub-diffusive systems: the case of granular single-file
D. Villamaina, A. Puglisi, A. Vulpiani
We study a gas of hard rods on a ring, driven by an external thermostat, with either elastic or inelastic collisions, which exhibits sub-diffusive behavior . W…
Capillary filling with randomly coated walls
Fabiana Diotallevi, Andrea Puglisi, Antonio Lamura +1
The motion of an air-fluid interface through an irregularly coated capillary is studied by analysing the Lucas-Washburn equation with a random capillary force. The pinning probabil…
Front pinning in capillary filling of chemically coated channels
F. Diotallevi, L. Biferale, S. Chibbaro +2
The dynamics of capillary filling in the presence of chemically coated heterogeneous boundaries is investigated, both theoretically and numerically. In particular, by mapping the e…
Fluctuations in granular gases
A. Barrat, A. Puglisi, E. Trizac +2
A driven granular material, e.g. a vibrated box full of sand, is a stationary system which may be very far from equilibrium. The standard equilibrium statistical mechanics is there…
Noise Rectification and Fluctuations of an Asymmetric Inelastic Piston
G. Costantini, U. Marini Bettolo Marconi, A. Puglisi
We consider a massive inelastic piston, whose opposite faces have different coefficients of restitution, moving under the action of an infinitely dilute gas of hard disks maintaine…
Fluctuation-Dissipation: Response Theory in Statistical Physics
Umberto Marini Bettolo Marconi, Andrea Puglisi, Lamberto Rondoni +1
General aspects of the Fluctuation-Dissipation Relation (FDR), and Response Theory are considered. After analyzing the conceptual and historical relevance of fluctuations in statis…
