The inelastic hard dimer gas: a non-spherical model for granular matter

Giulio Costantini, Umberto Marini Bettolo Marconi, Galina Kalibaeva +1

We study a two-dimensional gas of inelastic smooth hard dimers. Since the collisions between dimers are dissipative, being characterized by a coefficient of restitution $\alpha <1$, and…
