Dynamical response functions in models of vibrated granular media
arXiv:cond-mat/9809346 · doi:10.1103/PhysRevLett.82.3734
Abstract
In recently introduced schematic lattice gas models for vibrated dry granular media, we study the dynamical response of the system to small perturbations of shaking amplitudes and its relations with the characteristic fluctuations. Strong off equilibrium features appear and a generalized version of the fluctuation dissipation theorem is introduced. The relations with thermal glassy systems and the role of Edwards' compactivity are discussed.
