For the case of a constant $\\epsilon$ the particles spread logarithmically slow with time, whereas the velocity dependent coefficient yields a power law time-dependence. The impact of the difference in these time dependences on the properties of a freely cooling granular gas is discussed.", "revisions": [ { "version": "v2", "updated": "1999-05-26T18:05:15.000Z" } ], "analyses": { "keywords": [ "granular gases", "granular gas changes", "self-diffusion", "velocity dependent coefficient yields", "power law time-dependence" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
