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