Perturbation-induced radiation by the Ablowitz-Ladik soliton.

چکیده
An efficient formalism is elaborated to analytically describe dynamics of the Ablowitz-Ladik soliton in the presence of perturbations. This formalism is based on using the Riemann-Hilbert problem and provides the means of calculating evolution of the discrete soliton parameters, as well as shape distortion and perturbation-induced radiation effects. As an example, soliton characteristics are calculated for linear damping and quintic perturbations.

On integrable discretization of the inhomogeneous Ablowitz-Ladik model.
On integrable discretization of the inhomogeneous Ablowitz-Ladik model. Abstract An integrable discretization of the inhomogeneous Ablowitz-Ladik model with a linear force is introduced. Conditions on parameters of the discretization which are necessary for reproducing Bloch oscillations are obtained. In particular, it is shown that the step of the discretization must be comensurable with the p...
متن کاملPropagation of solitons in a randomly perturbed Ablowitz-Ladik chain.
This paper deals with the transmission of a soliton in a discrete, nonlinear, and random medium. A random lattice nonlinear Schrödinger equation is considered, where the randomness holds in the on-site potential or in the coupling coefficients. We study the interplay of nonlinearity, randomness, and discreteness. We derive effective evolution equations for the soliton parameters by applying a p...
متن کاملSolitons in coupled Ablowitz-Ladik chains
A model of two coupled Ablowitz-Ladik (AL) lattices is introduced. While the system as a whole is not integrable, it admits reduction to the integrable AL model for symmetric states. Stability and evolution of symmetric solitons are studied in detail analytically (by means of a variational approximation) and numerically. It is found that there exists a finite interval of positive values of the ...

is one of most important soliton equations in mathematics and physics. The study of discrete analogues of the NLS equation has received considerable attention recently from both physical and mathematical point of view.1, 2 The integrable discrete nonlinear Schrödinger (IDNLS) equation is given by i dψn dt = ψn+1 + ψn−1 + α|ψn|(ψn+1 + ψn−1) . (1.2) The IDNLS equation was originally derived by Ab...
متن کاملIntegrable Discretization of the Coupled Nonlinear Schrödinger Equations
A discrete version of the inverse scattering method proposed by Ablowitz and Ladik is generalized to study an integrable full-discretization (discrete time and discrete space) of the coupled nonlinear Schrödinger equations. The generalization enables one to solve the initial-value problem. Soliton solutions and conserved quantities of the full-discrete system are constructed.
