Origin of rebounds with a restitution coefficient larger than unity in nanocluster collisions (1208.0130v3)
Published 1 Aug 2012 in cond-mat.mes-hall
Abstract: We numerically investigate the mechanism of super rebounds for head-on collisions between nanoclusters in which the restitution coefficient is larger than unity. It is confirmed that the temperature and the entropy of the nanocluters decrease after the super rebounds by our molecular dynamics simulations. It is also found that the initial metastable structure plays a key role for the emergence of the super rebounds.
