A nonlinear quantum piston for the controlled generation of vortex rings
Natalia G. Berloff, Víctor M. Pérez‐García · arXiv (Cornell University) · 2010
We propose a simple way to manage interactions in Bose-Einstein condensates to generate vortex rings in a highly controllable way. The vortex rings are generated under the action of a quantum analogue of a classical piston pushing the condensed atoms through a small aperture.
