Abstract
A generalized Frenkel-Kontorova model with the Morse potentials is stu died. The phase diagram reflects the nonlinear nature of the Morse pot ential. The correspondences of the ground states and the orbits of the area-preserving map are studied numerically. Our results present a be tter simulation to the real systems.
