From: Spiraling elliptic Hermite-Gaussian solitons in nonlocal nonlinear media without anisotropy
Evolution of the first-order mode of the spiraling elliptic Hermite-Gaussian solitons. Profiles are plotted at different propagation distances: (a) z = 0, (b) z = T/4, (c) z = T/2, (d) z = 3T/4, and (e) z = T(=2.78). The beam width w x and w y in the x and y directions are plotted in (f), where solid black lines and dashed color lines denote the variational solution and numerical simulations respectively. The parameters are b = 1.2, c = 0.8, and w m = 20.
