Doubly periodic waves of a discrete nonlinear Schrödinger system with saturable nonlinearity
نویسنده
چکیده
A system of two discrete nonlinear Schrödinger equations of the Ablowitz-Ladik type with a saturable nonlinearity is shown to admit a doubly periodic wave, whose long wave limit is also derived. As a by-product, several new solutions of the elliptic type are provided for NLS-type discrete and continuous systems.

Thresholds for Breather Solutions of the Discrete Nonlinear Schrödinger Equation with Saturable and Power Nonlinearity
We consider the question of existence of periodic solutions (called breather solutions or discrete solitons) for the Discrete Nonlinear Schrödinger Equation with saturable and power nonlinearity. Theoretical and numerical results are proved concerning the existence and nonexistence of periodic solutions by a variational approach and a fixed point argument. In the variational approach we are res...

متن کاملGap Solitons in Periodic Discrete Nonlinear Schrödinger Equations
It is shown that the periodic DNLS, with cubic nonlinearity, possesses gap solutions, i. e. standing waves, with the frequency in a spectral gap, that are exponentially localized in spatial variable. The proof is based on the linking theorem in combination with periodic approximations. Mathematics subject classification: 35Q55, 35Q51, 39A12, 39A70, 78A40
متن کاملExperimental Results Related to Discrete Nonlinear Schrödinger Equations
Discrete nonlinear Schrödinger (DNLS) equations can be used to model numerous phenomena in atomic, molecular, and optical physics. The general feature of these various settings that leads to the relevance of DNLS models is a competition between nonlinearity, dispersion, and spatial discreteness (which can be periodic, quasiperiodic, or random). In three-dimensions (3D), the DNLS with cubic nonl...
متن کاملExact solutions of the Saturable Discrete Nonlinear Schrödinger Equation
Exact solutions to a nonlinear Schrödinger lattice with a saturable nonlinearity are reported. For finite lattices we find two different standing-wave-like solutions, and for an infinite lattice we find a localized soliton-like solution. The existence requirements and stability of these solutions are discussed, and we find that our solutions are linearly stable in most cases. We also show that ...
