Observation of cluster waves and their lifetime

Abstract

Using the molecular-dynamics technique we have studied a linear chain with quartic anharmonicity. Particular solutions of the equation of motion, representing clusters (domains), are shown to be relevant for a statistical description of the dynamics. A new excitation branch and the associated central-peak phenomenon are traced back to traveling cluster waves and their lifetime. © 1975 The American Physical Society.
