Typical evolution plots of fundamental mode solitons with different initial phase-front curvatures (a) C = −0.5, (b) C = 0, (c) C = 0.5; (d) profile of fundamental mode soliton (red line), lattice profile (blue line), and nonlinear refractive index distribution (green line) in the system (1). Other parameters are p = 0.5, Ω = 0.5, μ = 0, and U = 2.
