Bragg spectroscopy of the BCS pairing in atomic Fermi-Dirac gases — •J. Ruostekoski — Abteilung fur Quantenphysik; Uni Ulm; 89069 Ulm

We theoretically study the Bragg spectroscopy of a Fermi-Dirac gas in the presence of a superfluid state. The atoms undergo Bragg diffraction in two intersecting nonparallel laser beams by means of light-stimulated transitions. We show that the static structure function may be significantly increased due to superfluidity in the nearforward scattering. We acknowledge financial from DFG (Forschergruppe "Quantengase").
