Spatiotemporal accessible solitons in fractional dimensions
Wei-Ping Zhong, Milivoj R. Belić, Boris A. Malomed +2
We report solutions for solitons of the "accessible" type in globally nonlocal nonlinear media of fractional dimension (FD), viz., for self-trapped modes in the space of effective…
Interactions of incoherent localized beams in a photorefractive medium
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
We investigate numerically interactions between two bright or dark incoherent localized beams in an strontium barium niobate photorefractive crystal in one dimension, using the coh…
Interactions of Airy beams, nonlinear accelerating beams, and induced solitons in Kerr and saturable nonlinear media
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
We investigate numerically interactions between two in-phase or out-of-phase Airy beams and nonlinear accelerating beams in Kerr and saturable nonlinear media in one transverse dim…
The Nonlinear Talbot Effect of Rogue Waves
Yiqi Zhang, Milivoj R. Belić, Huaibin Zheng +4
Akhmediev and Kuznetsov-Ma breathers are rogue wave solutions of the nonlinear Schrödinger equation (NLSE). Talbot effect (TE) is an image recurrence phenomenon in the diffraction…
Soliton pair generation in the interactions of Airy and nonlinear accelerating beams
Yiqi Zhang, Milivoj Belić, Zhenkun Wu +4
We investigate numerically the interactions of two in-phase and out-of-phase Airy beams and nonlinear accelerating beams in Kerr and saturable nonlinear media, in one transverse di…
Optical vortices induced in nonlinear multilevel atomic vapors
Yiqi Zhang, Zhenkun Wu, Chenzhi Yuan +4
In a numerical investigation, we demonstrate the existence and curious evolution of vortices in a ladder-type three-level nonlinear atomic vapor with linear, cubic, and quintic sus…
Bragg gap solitons in symmetric lattices with competing nonlinearity
Shuang Liu, Caiwen Ma, Yiqi Zhang +1
The effect of competing nonlinearity on beam dynamics in parity-time symmetric potentials is investigated. By using numerical methods, the existence of gap soliton…
Azimuthons in weakly nonlinear waveguides of different symmetries
Yiqi Zhang, Stefan Skupin, Fabian Maucher +3
We show that weakly guiding nonlinear waveguides support stable propagation of rotating spatial solitons (azimuthons). We investigate the role of waveguide symmetry on the soliton…
