Spiraling solitons and multipole localized modes in nonlocal nonlinear media
Buccoliero, Daniel; Lopez-Aguayo, Servando; Skupin, Stephan; Desyatnikov, Anton S; Bang, Ole; Krolikowski, Wieslaw; Kivshar, Yuri
We analyze the propagation of rotating multi-soliton localized structures in optical media with spatially nonlocal nonlinearity. We demonstrate that nonlocality stabilizes the azimuthal breakup of rotating dipole as well as multipole localized soliton modes. We compare the results for two different models of nonlocal nonlinearity and suggest that the stabilization mechanism is a generic property of a spatial nonlocal nonlinear response independent of its particular functional form.
