Science, 1998
In much the same way as a glass lens can focus light, a sufficiently great mass--say a galaxy--can focus the light from a source far beyond it. Reporting in the 1 April Monthly Notices of the Royal Astronomical Society, a team of U.S. and European astronomers has now used three telescopes to pin down an "Einstein ring," the complete circular image ...

A storage ring for Bose-Einstein condensates
Conference on Lasers and Electro-Optics/International Quantum Electronics Conference and Photonic Applications Systems Technologies, 2004A vertically-oriented magnetic storage ring for cold atoms has been demonstrated and Bose-Einstein condensates have been formed in a localised section of the torus.

Einstein rings unveil the invisible
Physics World, 1990Over 70 years ago a team of astronomers set off from Britain in a small boat, heading for the South Atlantic to observe a total solar eclipse. The observations they made marked the birth of a technique which today allows the masses of galaxies to be measured, and which produces some of the most startling pictures in modern astronomy.

Vortex rings in toroidal Bose-Einstein condensates
Laser Physics, 2008We study vortex ring solutions of the Gross-Pitaevskii equation for Bose-Einstein condensates confined in toroidal traps. Analogously to the Feynman-Onsager ansatz for a single vortex line, we assume a condensate wavefunction that describes a quantized vortex ring.
