Optical detection of a BCS phase transition in a trapped gas of fermionic atoms
arXiv:cond-mat/9902350 · doi:10.1103/PhysRevA.60.504
Abstract
Light scattering from a spin-polarized degenerate Fermi gas of trapped ultracold Li-6 atoms is studied. We find that the scattered light contains information which directly reflects the quantum pair correlation due to the formation of atomic Cooper pairs resulting from a BCS phase transition to a superfluid state. Evidence for pairing can be observed in both the space and time domains.
