Generation of optical vortices by using binary vortex producing lenses
(Optical Society Of America, 2015-02)
Experimental high-quality optical vortices of different topological charges are generated by using a vortex producing lens with two phase levels. In our setup, the lens is displayed on a liquid-crystal spatial light modulator ...
Stationary rings of vortices in nonrotating Bose-Einstein condensates
(American Physical Society, 2008-11)
We numerically obtain stationary rings of vortices in pancake-shaped Bose-Einstein condensates confined in a three-dimensional nonrotating trap. For this purpose we use a static axisymmetric trapping potential that can ...
Stability and evolution of uniform-vorticity dipoles
(Journal of Fluid Mechanics, 2011)
Using an iterative algorithm, a family of stationary two-dimensional vortical dipoles is constructed, including translational (symmetric and asymmetric about the translation axis) and orbital (i.e. moving in circles) ...
Metastable off-axis vortices in nonrotating Bose-Einstein condensates
(IOP Publishing, 2008-02)
We propose a scenario for studying vortices confined by nonrotating traps. For this purpose we model a polynomial trapping potential that can sustain locally stable off-axis vortices. We also describe a simple numerical ...
