Energy fluctuations in a randomly driven granular fluid
We study the behavior of the energy fluctuations in the stationary state of a uniformly heated granular gas. The equation for the one-time two-particle correlation function is derived and the hydrodynamic eigenvalues are identified. Explicit predictions are subsequently determined for energy fluctua...

| Resumo: | We study the behavior of the energy fluctuations in the stationary state of a uniformly heated granular gas. The equation for the one-time two-particle correlation function is derived and the hydrodynamic eigenvalues are identified. Explicit predictions are subsequently determined for energy fluctuations. The results explain Monte Carlo numerical data reported in previous studies [Eur. Phys. J. B 51, 377 (2006)]. |
