Asymmetric solitons.
Amplitude distributions of the u- (a) and v- (b) components of the stable asymmetric fundamental soliton with g = 1 and N = 10, M = 20 (i.e., the asymmetry ratio is R = 0.5). Panels (c) and (d) display dependences between the larger norm (M) and the two chemical potentials, λ and μ, respectively [see Eqs (5), (12) and (13)], for different values of the asymmetric ratio, R, at g = 1. Solid lines represent stable numerical solutions, and triangles depict the VA-predicted analytical results from Eqs (10)–(13).
