One-dimensional gap solitons in quintic and cubic-quintic Fractional nonlinear Schrödinger equations with a periodically modulated linear potential
Liangwei Zeng, Jianhua Zeng
Competing nonlinearities, such as the cubic (Kerr) and quintic nonlinear terms whose strengths are of opposite signs (the coefficients in front of the nonlinearities), exist in var…
Gaussian-like and flat-top solitons of atoms with spatially modulated repulsive interactions
Liangwei Zeng, Jianhua Zeng
Solitons, nonlinear particle-like excitations with inalterable properties (amplitude, shape, and velocity) as they propagate, are omnipresent in many branches of science---and in p…
One-dimensional solitons in fractional Schrödinger equation with a spatially modulated nonlinearity: nonlinear lattice
Liangwei Zeng, Jianhua Zeng
The existence and stability of stable bright solitons in one-dimensional (1D) media with a spatially periodical modulated Kerr nonlinearity are demonstrated by means of the linear-…
Gap-type dark localized modes in a Bose-Einstein condensate with optical lattices
Liangwei Zeng, Jianhua Zeng
Bose-Einstein condensate (BEC) exhibits a variety of fascinating and unexpected macroscopic phenomena, and has attracted sustained attention in recent years--particularly in the fi…
A purely Kerr nonlinear model admitting flat-top solitons
Liangwei Zeng, Jianhua Zeng, Yaroslav V. Kartashov +1
We elaborate one- and two-dimensional (1D and 2D) models of media with self-repulsive cubic nonlinearity, whose local strength is subject to spatial modulation that admits the exis…
