Solitons in a parametrically driven damped discrete nonlinear Schrödinger equation
M. Syafwan, H. Susanto, S. M. Cox
We consider a parametrically driven damped discrete nonlinear Schrödinger (PDDNLS) equation. Analytical and numerical calculations are performed to determine the existence and stab…
An instability criterion for nonlinear standing waves on nonzero backgrounds
R. K. Jackson, R. Marangell, H. Susanto
A nonlinear Schrödinger equation with repulsive (defocusing) nonlinearity is considered. As an example, a system with a spatially varying coefficient of the nonlinear term is studi…
Intrinsic localized modes in coupled DNLS equations from the anti-continuum limit
K. Li, P. G. Kevrekidis, H. Susanto +1
In the present work, we generalize earlier considerations for intrinsic localized modes consisting of a few excited sites, as developed in the one-component discrete nonlinear Schr…
Unstable gap solitons in inhomogeneous Schrodinger equations
R. Marangell, H. Susanto, C. K. R. T. Jones
A periodically inhomogeneous Schrodinger equation is considered. The inhomogeneity is reflected through a non-uniform coefficient of the linear and non-linear term in the equation.…
Variational approximations for travelling solitons in a discrete nonlinear Schrödinger equation
M. Syafwan, H. Susanto, S. M. Cox +1
Travelling solitary waves in the one-dimensional discrete nonlinear Schrödinger equation (DNLSE) with saturable onsite nonlinearity are studied. A variational approximation (VA) fo…
