SPONTANEOUSLY APPEARING DISCRETE MOVING KINKS IN NONLINEAR ACOUSTIC CHAIN WITH REALISTIC POTENTIAL
Molecular dynamic simulations are performed to investigate a long-time evolution of different initial signals in nonlinear acoustic chains with realistic Exp-6 potential and with power potentials. First, in the chain with realistic potential, long-lifetime kink-shaped excitations are found in the sy...
