Nonlinear Waves in Two-Dimensional (2D) Square Lattice Frenkel-Kontorova (FK) System
- 1. Department of Physics, Northwest Normal University, Lanzhou 730070 (China)
Description
A 2D square lattice is studied. By using the continuum approximation, we set up the differential equations of motion for an arbitrary particle in the square lattice which subjects to an external periodic substrate potential. The exact solitary waves of the system are found for special cases. We conclude that the adhesive force f and the angle α between propagation directions of upper and lower layers can affect these waves.
