Pseudospectral Renormalization Method for Solitons in Quasicrystal Lattice with the Cubic-Quintic Nonlinearity
Figure 19
Nonlinear evolution of the lattice soliton without the optical lattice with for the self-focusing cubic and the self-focusing quintic model. (a) Peak amplitude of the lattice soliton as a function of the propagation distance. The initial condition is taken as the lattice soliton with a 0.01 noise in the amplitude and phase; (b) cross section along the diagonal axis of the lattice soliton before and after evolutions ( and ).
