PT-symmetry Management in Oligomer Systems
R. L. Horne, J. Cuevas, P. G. Kevrekidis +3
We study the effects of management of the PT-symmetric part of the potential within the setting of Schrödinger dimer and trimer oligomer systems. This is done by rapidly modulating…
Interactions of solitons with a Gaussian barrier: Splitting and recombination in quasi-1D and 3D
J. Cuevas, P. G. Kevrekidis, B. A. Malomed +2
The interaction of matter-wave solitons with a potential barrier is a fundamentally important problem, and the splitting and subsequent recombination of the soliton by the barrier…
Escape Dynamics in the Discrete Repulsive ϕ^4-Model
V. Achilleos, A. Álvarez, J. Cuevas +4
We study deterministic escape dynamics in the framework of the discrete Klein-Gordon modelwith a repulsive quartic on-site potential. Using a combination of analytical techniques,…
Dark-bright gap solitons in coupled-mode one-dimensional saturable waveguide arrays
Rong Dong, Christian E. Rüter, Detlef Kip +4
In the present work, we consider the dynamics of dark solitons as one mode of a defocusing photorefractive lattice coupled with bright solitons as a second mode of the lattice. Our…
Breathers and kinks in a simulated crystal experiment
Q. Dou, J. Cuevas, J. C. Eilbeck +1
We develop a simple 1D model for the scattering of an incoming particle hitting the surface of mica crystal, the transmission of energy through the crystal by a localized mode, and…
Solitons in quasi one-dimensional Bose-Einstein condensates with competing dipolar and local interactions
J. Cuevas, Boris A. Malomed, P. G. Kevrekidis +1
We study families of one-dimensional matter-wave bright solitons supported by the competition of contact and dipole-dipole (DD) interactions of opposite signs. Soliton families are…
