Lack of collective motion in granular gases of rotators

Abstract The dynamics of gases made particles interacting dissipatively {known as granular gases{ can be fully described by the translational and rotational motion individual particles; however, most results in field refer to limit smooth particles, which implies that degrees freedom are suppressed. Here we investigate opposite limit: consider a gas where suppressed, key rotational. Our indicate for many-particle systems pure rotators collective effects almost completely This is sharp contrast other conventional matter dominate kinetics.
