Stimulus dependence of the collective vibration of atoms in an icosahedral cluster
首发时间:2007-10-22
Abstract:Molecular dynamical calculations of the thermal relaxation of a Lennard-Jones 147-atom cluster revealed that the collective vibration of the atoms in the cluster at the initial stage of relaxation upon perturbation of dislocation and that the stability of the collective vibration is affected by the strength and extent of the mechanical stimulus. A stronger or larger-scale stimulus will cause the vibration to decay faster compared to the vibration stimulated by a weaker or small-scale stimulus. Understanding may suggest a possible way on how the stimulus-introduced energy is transferred in the cluster: the collective vibration of atoms and its decay.
