Structure factors in granular experiments with homogeneous fluidization
A. Puglisi, A. Gnoli, G. Gradenigo +2
Velocity and density structure factors are measured over a hydrodynamic range of scales in a horizontal quasi-2d fluidized granular experiment, with packing fractions $ϕ\in[10%,40%…
Non-equilibrium fluctuations in a driven stochastic Lorentz gas
G. Gradenigo, U. Marini Bettolo Marconi, A. Puglisi +1
We study the stationary state of a one-dimensional kinetic model where a probe particle is driven by an external field E and collides, elastically or inelastically, with a bath of…
Fluctuating hydrodynamics and correlation lengths in a driven granular fluid
Giacomo Gradenigo, Alessandro Sarracino, Dario Villamaina +1
Static and dynamical structure factors for shear and longitudinal modes of the velocity and density fields are computed for a granular system fluidized by a stochastic bath with fr…
Estimate of temperature and its uncertainty in small systems
M. Falcioni, A. Puglisi, A. Sarracino +2
The energy of a finite system thermally connected to a thermal reservoir may fluctuate, while the temperature is a constant representing a thermodynamic property of the reservoir.…
Growing non-equilibrium length in granular fluids: from experiment to fluctuating hydrodynamics
Giacomo Gradenigo, Alessandro Sarracino, Dario Villamaina +1
Velocity correlations in a 2D granular fluid are studied in experiments and numerical simulations. The transverse component of the velocity structure factor reveals two well define…
On anomalous diffusion and the out of equilibrium response function in one-dimensional models
D Villamaina, A Sarracino, G Gradenigo +2
We study how the Einstein relation between spontaneous fluctuations and the response to an external perturbation holds in the absence of currents, for the comb model and the elasti…
