Escape dynamics in the discrete repulsive φ4 model
(2013)
We study deterministic escape dynamics of the discrete Klein-Gordon model with a repulsive quartic on-site potential. Using a combination of analytical techniques, based on differential and algebraic inequalities and ...

Dark-bright discrete solitons: a numerical study of existence, stability and dynamics
(2011)
the present work, we numerically explore the existence and stability properties of different types of configurations of dark-bright solitons, dark-bright soliton pairs and pairs of dark-bright and dark solitons in discrete ...

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 ...
