Maxwell Fronts in the Discrete Nonlinear Schrödinger Equations with Competing Nonlinearities
Farrell Theodore Adriano, Hadi Susanto
In discrete nonlinear systems, the study of nonlinear waves has revealed intriguing phenomena in various fields such as nonlinear optics, biophysics, and condensed matter physics.…
Fluxon analogues and dark solitons in linearly coupled Bose-Einstein condensates
Muhammad I. Qadir, Hadi Susanto, Paul C. Matthews
Two effectively one-dimensional parallel coupled Bose-Einstein condensates in the presence of external potentials are studied. The system is modelled by linearly coupled Gross-Pita…
Interlaced solitons and vortices in coupled DNLS lattices
J. Cuevas, Q. E. Hoq, H. Susanto +1
In the present work, we propose a new set of coherent structures that arise in nonlinear dynamical lattices with more than one components, namely interlaced solitons. These are wav…
High-Order-Mode Soliton Structures in Two-Dimensional Lattices with Defocusing Nonlinearity
P. G. Kevrekidis, H. Susanto, Z. Chen
While fundamental-mode discrete solitons have been demonstrated with both self-focusing and defocusing nonlinearity, high-order-mode localized states in waveguide lattices have bee…
Dark Solitons in Discrete Lattices: Saturable versus Cubic Nonlinearities
E. P. Fitrakis, P. G. Kevrekidis, H. Susanto +1
In the present work, we study dark solitons in dynamical lattices with the saturable nonlinearity and compare them with those in lattices with the cubic nonlinearity. This comparis…
Discrete surface solitons in two dimensions
H. Susanto, P. G. Kevrekidis, B. A. Malomed +2
We investigate fundamental localized modes in 2D lattices with an edge (surface). Interaction with the edge expands the stability area for ordinary solitons, and induces a differen…
