Two-dimensional multipole solitons in nonlocal nonlinear media.
TLDR
The experimental observation of scalar multipole solitons in highly nonlocal nonlinear media, including dipole, tripole, quadrupole, and necklace-typesolitons, organized as arrays of out-of-phase bright spots is presented.Abstract:
We present the experimental observation of scalar multipole solitons in highly nonlocal nonlinear media, including dipole, tripole, quadrupole, and necklace-type solitons, organized as arrays of out-of-phase bright spots. These complex solitons are metastable, but with a large parameters range where the instability is weak, permitting their experimental observation.read more

Optical spatial solitons: historical overview and recent advances

Propagation of Laguerre?Gaussian beams in nonlocal nonlinear media
Dongmei Deng,Qi Guo +1 more
TL;DR: In this article, the exact analytical Laguerre-Gaussian (LG) solutions are derived in strongly nonlocal nonlinear media in a cylindrical coordinate system, and the comparisons of analytical solutions with numerical simulations of the non-local non-linear Schrodinger equation (NNLSE) show that the analytical LG solutions are in good agreement with the numerical simulations in the case of strong nonlocality.

Collapse arrest and soliton stabilization in nonlocal nonlinear media.
TL;DR: It is proved rigorously by bounding the Hamiltonian that nonlocality of the nonlinearity prevents collapse in, e.g., Bose-Einstein condensates and optical Kerr media in all physical dimensions.

Nonlocal spatial soliton interactions in nematic liquid crystals.
TL;DR: The interaction between spatial optical solitons in undoped nematic liquid crystals is governed by reorientational nonlinearity with a significant nonlocality, and a scalar model accounts for the main features that were experimentally observed.
