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%…
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…
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…
