Submitted for the MAR08 Meeting of The American Physical Society Interference between atomic Bardeen-Cooper-Schrieffer gases TUN WANG, Austrian Academy of Science, SUSANNE YELIN, Univ. of Connecticut — We study the interference between two atomic Bardeen-CooperSchrieffer (BCS) gases using noise correlations. Fringes as seen in the interference between two Bose-Einstein Condensates (BECs) do not to exist due to the requirement that two BCS gases have to initially overlap to interfere. This requirement results from the fact that the spin up and spin down fermions in a Cooper pair have opposite momenta. Nevertheless, BCS gases still interfere with each other, and their interference patterns share many aspects with those of BECs.

متن کاملPopulation of closed-channel molecules in trapped Fermi gases with broad Feshbach resonances.
We compute the fraction of closed-channel molecules in trapped atomic Fermi gases, over the entire range of accessible fields and temperatures. We use a two-channel model of Bardeen-Cooper-Schrieffer-Bose-Einstein-condensation crossover theory at general temperature , and show that this fraction provides a measure of the T-dependent pairing gap. Our calculations, containing no free parameters, ...

Submitted for the MAR08 Meeting of The American Physical Society Initial States of BEC mixtures Produced by Cooling in the Presence of a Feshbach Resonance LAURA HALMO, Georgia Southern University, MARK EDWARDS, Georgia Southern University and NIST — We have studied the types of Bose–Einstein condensate (BEC) mixtures produced as a result of different cooling paths. These results are relevant t...

متن کاملGround-state properties of Fermi gases in the strongly interacting regime.
The ground-state energies and pairing gaps in dilute superfluid Fermi gases have now been calculated with the quantum Monte Carlo method without detailed knowledge of their wave functions. However, such knowledge is essential to predict other properties of these gases such as density matrices and pair distribution functions. We present a new and simple method to optimize the wave functions of q...
