Stability of two-dimensional spatial solitons in nonlocal nonlinear media
arXiv:nlin/0603014 · doi:10.1103/PhysRevE.73.066603
Abstract
We discuss existence and stability of two-dimensional solitons in media with spatially nonlocal nonlinear response. We show that such systems, which include thermal nonlinearity and dipolar Bose Einstein condensates, may support a variety of stationary localized structures - including rotating spatial solitons. We also demonstrate that the stability of these structures critically depends on the spatial profile of the nonlocal response function.
