Scaling and Universality of Critical Fluctuations in Granular Gases
Scaling and Universality of Critical Fluctuations in Granular Gases
The global energy fluctuations of a low density gas granular gas in the homogeneous cooling state near its clustering instability are studied by means of molecular dynamics simulations. The relative dispersion of the fluctuations is shown to exhibit a power-law divergent behavior. Moreover, the probability distribution of the fluctuations presents …
