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...

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...

Spinor Bose-Einstein condensates in optical traps

We have studied the equilibrium state of spinor condensates in an optical trap [1]. In contrast to magnetically trapped condensates, spinor condensates have the orientation of the spin as a degree of freedom, which can be described by a multi-component wavefunction (one for each magnetic sublevel). In an F=1 spinor condensate subject to spin relaxation, two mF=0 atoms can collide and produce a ...
