Ultraslow Light & Bose-Einstein Condensates Two-way Control with Coherent Light & Atom Fields

Manipulating Bose-Einstein condensates with laser light

A dilute gas Bose-Einstein condensate was probed and manipulated by off-resonant laser beams. Spontaneous and stimulated off-resonant light scatterings were studied experimentally. Stimulated, two-photon Bragg scattering was used for spectroscopic measurement of the mean-field energy and of the intrinsic momentum uncertainty of the condensate. The high momentum and energy resolution of this met...

Storing and processing optical information with ultraslow light in Bose-Einstein condensates

We theoretically explore coherent information transfer between ultraslow light pulses and Bose-Einstein condensates (BEC’s) and find that storing light pulses in BEC’s allows the coherent condensate dynamics to process optical information. We consider BEC’s of alkali atoms with a L energy level configuration. In this configuration, one laser (the coupling field) can cause a pulse of a second pu...

Spinor Condensates and Light Scattering from Bose-einstein Condensates

These notes discuss two aspects of the physics of atomic Bose-Einstein condensates: optical properties and spinor condensates. The first topic includes light scattering experiments which probe the excitations of a condensate in both the free-particle and phonon regime. At higher light intensity, a new form of superradiance and phase-coherent matter wave amplification were observed. We also disc...
