Abstract: Abstract In this paper we study the discrete solitons in nonlinear Schrodinger lattices with hard potentials. We first derive some sufficient conditions for the existence of discrete solitons in the anti-continuum limit. We then establish… read more here.

Abstract: We analytically and numerically investigate beyond-band discrete solitons, which present a completely new class of stable localized out-gap solitons with detunings being located beyond the two bands of the linear plane waves in a periodic… read more here.

Abstract: Discrete solitons (DS), which could propagate without diffraction in the waveguide array (WA), have attracted great attention. However, its applications are limited to incident light with high power. Here, based on the d.c. Kerr effect… read more here.
