2014/12/25
In the present paper, we revisit nonlinearity management of the time-periodic nonlinear Schrödinger equation and the related averaging procedure. By means of rigorous estimates, we show that the ...
Discrete surface solitons in two dimensions
On the edge of the two-dimensional lattice the induced dipole lattice vortex solitons lattice

2014/12/25
We investigate fundamental localized modes in two-dimensional lattices with an edge (surface). The interaction with the edge expands the stability area for fundamental solitons, and induces a differen...
Discrete skyrmions in 2+1 and 3+1 dimensions
Lattice Skyrme model discrete model discretization
