Collisions and fusion of one- and two-dimensional solitons driven by potential troughs in the cubic-quintic nonlinear Schrödinger equations
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +2
We study the formation and collision of one- and two-dimensional (1D and 2D) Gaussian-shaped and flat-top (FT) solitons in the framework of the nonlinear Schrödinger equation with…

Solitons in composite linear-nonlinear moiré lattices
Liangwei Zeng, Boris A. Malomed, Dumitru Mihalache +2
We produce families of two-dimensional gap solitons (GSs) maintained by moiré lattices (MLs) composed of linear and nonlinear sublattices, with the defocusing sign of the nonlinea…
