From nodeless clouds and vortices to gray ring solitons and symmetry-broken states in two-dimensional polariton condensates
(2014)
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
(2011)
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 ...
