Angular velocity distribution of a granular planar rotator in a thermalized bath
arXiv:cond-mat/0610112 · doi:10.1103/PhysRevE.75.051307
Abstract
The kinetics of a granular planar rotator with a fixed center undergoing inelastic collisions with bath particles is analyzed both numerically and analytically by means of the Boltzmann equation. The angular velocity distribution evolves from quasi-gaussian in the Brownian limit to an algebraic decay in the limit of an infinitely light particle. In addition, we compare this model with a planar rotator with a free center. We propose experimental tests that might confirm the predicted behaviors.
