Collapse suppression and stabilization of dipole solitons in two-dimensional media with anisotropic semi-local nonlinearity
Fangwei Ye, Boris A. Malomed, Yingji He +1
We consider the impact of anisotropic nonlocality on the arrest of the collapse and stabilization of dipole-mode (DM) solitons in two-dimensional (2D) models of optical media with…
Solitary modes in nonlocal media with inhomogeneous self-repulsive nonlinearity
Yingji He, Boris A. Malomed
We demonstrate the existence of two species of stable bright solitons, fundamental and dipole ones, in one-dimensional self-defocusing nonlocal media, with the local value of nonli…
Propagation dynamics of abruptly autofocusing circular Airy-Gaussian vortex beams in the fractional Schrödinger equation
Shangling He, Boris A. Malomed, Dumitru Mihalache +4
We introduce axisymmetric Airy-Gaussian vortex beams in a model of an optical system based on the (2+1)-dimensional fractional Schrödinger equation, characterized by its Lévy ind…
Generations of polygonal soliton clusters and fundamental solitons by radially-azimuthally phase-modulated necklace-ring beams in dissipative systems
Yingji He, Dumitru Mihalache, Boris A. Malomed +3
We demonstrate that, in a two-dimensional dissipative medium described by the cubic-quintic (CQ) complex Ginzburg-Landau (CGL) equation with the viscous (spectral-filtering) term,…
Topologically enhanced nonlinear optical response of graphene nanoribbon heterojunctions
Hanying Deng, Zhihao Qu, Yingji He +3
We study the nonlinear optical properties of heterojunctions made of graphene nanoribbons (GNRs) consisting of two segments with either the same or different topological properties…
Localized modes in dissipative lattice media: An overview
Yingji He, Boris A. Malomed, Dumitru Mihalache
We overview recent theoretical studies of the dynamics of one- and two-dimensional spatial dissipative solitons in models based on the complex Ginzburg-Landau equations with the cu…
