We study the topological physics in nonlinear Schrödinger systems on lattices. We employ the quench dynamics to explore the phase diagram, where a pulse is given to a lattice point …

Discrete systems with long-range interactions are considered. Continuous medium models as continuous limit of discrete chain system are defined. Long-range interactions of chain …
We study the nonlinear effect on topological edge states by including a nonlinear term to a Chern insulator which has two chiral edge states with opposite chiralities. We explore …

In this work, we introduce a spatially discrete model that is a modification of the well-known α- Fermi–Pasta–Ulam chain with damping. The system is perturbed at one end by a harmonic …

Using the fact that extremum of variation of generalized action can lead to the fractional dynamics in the case of systems with long-range interaction and long-term memory function …
We study the dynamics of the Schrödinger equation with a fractional Laplacian (− Δ) α, and the decoherence of the solution is observed. Analytically, we obtain equations of motion for …
There are different approaches to discretization of the Schrödinger equation with some approximations. In this paper we derive a discrete equation that can be considered as exact …
We study—experimentally, theoretically, and numerically—nonlinear excitations in lattices of magnets with long-range interactions. We examine breather solutions, which are spatially …

We consider a chain of nonlinear oscillators with long-range interaction of the type 1∕ l 1+ α, where l is a distance between oscillators and 0< α< 2. In the continuous limit, the …
