Beating dark-dark solitons in Bose-Einstein condensates [Article]
Motivated by recent experimental results, we study beating dark-dark solitons as a prototypical coherent structure that emerges in two-component Bose-Einstein condensates. We showcase their connection to dark- bright ...
Breathers for the discrete nonlinear Schrödinger equation with nonlinear hopping [Article]
We discuss the existence of breathers and lower bounds on their power, in nonlinear Schrödinger lattices with nonlinear hopping. Our methods extend from a simple variational approach to fixed-point arguments, deriving lower ...
From nodeless clouds and vortices to gray ring solitons and symmetry-broken states in two-dimensional polariton condensates [Article]
We consider the existence, stability and dynamics of the nodeless state and fundamental nonlinear excitations, such as vortices, for a quasi-two-dimensional polariton condensate in the presence of pumping and nonlinear ...
Josephson tunnelling of dark solitons in a double-well potential [Article]
We study the dynamics of matter waves in an effectively one-dimensional Bose-Einstein condensate in a double-well potential. We consider in particular the case when one of the double wells confines excited states. Similar ...
Dark-bright discrete solitons: a numerical study of existence, stability and dynamics [Article]
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 ...
