Vortex solutions of the defocusing discrete nonlinear Schroedinger equation
(American Institute of Physics, 2009)
We consider the existence, stability and dynamical evolution of dark vortex states in the two-dimensional defocusing DNLS equation, a model of interest both to atomic physics and to nonlinear optics. Our considerations are ...

Vortex solutions of the discrete Gross-Pitaevskii equation starting from the anti-continuum limit
(2009)
In this paper, we consider the existence, stability and dynamical evolution of dark vortex states in the two-dimensional defocusing discrete nonlinear Schrödinger model, a model of interest both to atomic physics and to ...

Interlaced solitons and vortices in coupled DNLS lattices
(2009)
In the present work, we propose a new set of coherent structures that arise in nonlinear dynamical lattices with more than one component, namely interlaced solitons. In the anti-continuum limit of uncoupled sites, these ...
