Abstract

The possibility of using atom optics techniques to directly study the coherence present in a gas of fermionic atoms that went through Bardeen-Cooper-Schrieffer (BCS) transition was studied. An atomic grating generated by a pulsed standing-wave laser field was proposed to manipulate the superfluid state in a quantum degenerate gas of fermionic atoms. It was shown that density oscillations of the gas caused by the atomic grating exhibited a much longer coherence time than in the normal Fermi gas in the presence of atomic Cooper pairs.
