Soliton gyroscopes in media with spatially growing repulsive nonlinearity

R Driben, YV Kartashov, BA Malomed, T Meier… - Physical review …, 2014 - APS
We find that the recently introduced model of self-trapping supported by a spatially growing
strength of a repulsive nonlinearity gives rise to robust vortex-soliton tori, ie, three …

Observation of stable-vector vortex solitons

Y Izdebskaya, G Assanto, W Krolikowski - Optics Letters, 2015 - opg.optica.org
We report on the first experimental observation of stable-vector vortex solitons in nonlocal
nonlinear media with a reorientational response, such as nematic liquid crystals. These …

Exact and approximate solutions for optical solitary waves in nematic liquid crystals

JML MacNeil, NF Smyth, G Assanto - Physica D: Nonlinear Phenomena, 2014 - Elsevier
