Theory of a Slow-Light Catastrophe
Ulf Leonhardt
In diffraction catastrophes such as the rainbow the wave nature of light resolves ray singularities and draws delicate interference patterns. In quantum catastrophes such as the bl…
Quantum catastrophe of slow light
Ulf Leonhardt
Catastrophes are at the heart of many fascinating optical phenomena. The rainbow, for example, is a ray catastrophe where light rays become infinitely intense. The wave nature of l…
Optical Analog of the Iordanskii Force in a Bose-Einstein Condensate
U. Leonhardt, P. Ohberg
A vortex in a Bose-Einstein condensate generates the optical analog of the Aharonov-Bohm effect when illuminated with slow light. In contrast to the original Aharonov-Bohm effect t…
A Primer to Slow Light
U. Leonhardt
Laboratory-based optical analogs of astronomical objects such as black holes rely on the creation of light with an extremely low or even vanishing group velocity (slow light). Thes…
