Bragg spectroscopy with an accelerating Bose-Einstein condensate
arXiv:cond-mat/0307224 · doi:10.1103/PhysRevA.68.043611
Abstract
We present the results of Bragg spectroscopy performed on an accelerating Bose-Einstein condensate. The Bose condensate undergoes circular micro-motion in a magnetic TOP trap and the effect of this motion on the Bragg spectrum is analyzed. A simple frequency modulation model is used to interpret the observed complex structure, and broadening effects are considered using numerical solutions to the Gross-Pitaevskii equation.
