Dynamics of two-dimensional coherent structures in nonlocal nonlinear media
Dynamics of two-dimensional coherent structures in nonlocal nonlinear media
We study stability and dynamics of the single cylindrically symmetric solitary structures and dipolar solitonic molecules in spatially nonlocal media. The main properties of the solitons, vortex solitons, and dipolar solitons are investigated analytically and numerically. The vortices and higher-order solitons show the transverse symmetry-breaking azimuthal instability below some critical …
