Abstract The cubic complex Ginzburg-Landau equation is one of the most-studied nonlinear
equations in the physics community. It describes a vast variety of phenomena from nonlinear …

We study numerically the dynamical instabilities and splitting of singly and doubly quantized
composite vortices in two-component Bose-Einstein condensates harmonically confined to …

In the framework of the nonlinear Schrödinger equation (NLSE) as a model of superflow we
found that multicharged vortices are very long-living objects, contrary to the accepted …

We show numerically that a rotating, harmonically trapped mixture of two Bose-Einstein-
condensed superfluids can—contrary to its single-species counterpart—contain a multiply …

We study the splitting dynamics of giant vortices in dilute Bose-Einstein condensates by
numerically integrating the three-dimensional Gross-Pitaevskii equation in time. By taking …

We develop an asymptotic theory describing the dynamics of two-dimensional dark
quasisolitons in a smoothly inhomogeneous Bose-Einstein condensate (BEC) with repulsive …

We show that topological vortex pum** can be implemented for a dilute Bose-Einstein
condensate confined in a magnetic time-averaged orbiting potential trap with axial optical …

We prepared a ring-shaped Bose–Einstein condensate with quantized circulation by
imprinting a linear azimuthal phase. A doubly quantized vortex (DQV) can be generated and …

In 1995, atomic physics took a quantum leap with the experimental discovery of almost ideal
Bose-Einstein condensation in dilute gases of alkali atoms. The gaseous condensates offer …

The dynamical properties of vortices in superfluid systems are investigated theoretically and
numerically. A novel nonlocal nonlinear Schrodinger Lagrangian for the superfluid system is …
