Abstract

Description

Molecular dynamic simulations are performed to investigate a long-time evolution of different type initial signals in nonlinear acoustic chains with realistic Exp-6 potential and with power ones. Finite number of long-lifetime kink-shaped excitations is observed in the system in thermodynamic equilibrium. Dynamical equilibrium between the processes of their growth and decay is found.
