Slow light, superadiabaticity and shape-preserving pulses
U. Leonhardt, L. C. Davila Romero
We analyze the nonlinear dynamics of atomic dark states in Lambda configuration that interact with light at exact resonance. We found a generalization of shape-preserving pulses [R…
Slow-light solitons
Ulf Leonhardt
A new type of soliton with controllable speed is constructed generalizing the theory of slow-light propagation to an integrable regime of nonlinear dynamics. The scheme would allow…
The Perfectly Matched Layer for nonlinear and matter waves
C. Farrell, U. Leonhardt
We discuss how the Perfectly Matched Layer (PML) can be adapted to numerical simulations of nonlinear and matter wave systems, such as Bose-Einstein condensates. We also present so…
Bogoliubov theory of the Hawking effect in Bose-Einstein condensates
U. Leonhardt, T. Kiss, P. Ohberg
Artificial black holes may demonstrate some of the elusive quantum properties of the event horizon, in particular Hawking radiation. One promising candidate is a sonic hole in a Bo…
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…
