Superradiant Scattering
Aaron J. Hand
Researchers at the Massachusetts Institute of Technology studied Rayleigh scattering off a Bose-Einstein condensate, an experiment that produced superradiant scattering.
As described in the July 23 issue of
Science, the researchers exposed the condensate to an off-resonant laser pulse. Though the photons would normally scatter randomly, the single quantum state of the atoms in a Bose-Einstein condensate allowed the light to maintain its coherence. Long-lived excitations in the condensate, the authors explained, "provide a positive feedback and lead to directional Rayleigh scattering."
The experiment demonstrated the symmetry between optical lasers and atom lasers.
