PT-symmetry management in oligomer systems
(2013)
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 in time the gain/loss profile. This gives ...

Coupled backward- and forward-propagating solitons in a composite right- and left-handed transmission line
(2013)
We study the coupling between backward- and forward-propagating wave modes, with the same group velocity, in a composite right- and left-handed nonlinear transmission line. Using an asymptotic multiscale expansion technique, ...

Scattering of atomic dark-bright solitons from narrow impurities
(2013)
In this work, we examine the collision of an atomic dark-bright soliton, in a two-component Bose-Einstein condensate, with a Gaussian barrier or well. Our study has both an experimental component and a theoretical/computational ...
