Finite temperature effects in light scattering off Cooper-paired Fermi atoms
نویسنده
چکیده
We study stimulated light scattering off a superfluid Fermi gas of atoms at finite temperature. We derive response function that takes into account vertex correction due to final state interactions; and analyze finite temperature effects on collective and quasiparticle excitations of a uniform superfluid Fermi gas. Light polarization is shown to play an important role in excitations. Our results suggest that it is possible to excite Bogoliubov-Anderson phonon at a large scattering length by light scattering.

Light scattering in Cooper-paired Fermi atoms
We present a detailed theoretical study of light scattering off superfluid trapped Fermi gas of atoms at zero temperature. We apply Nambu-Gorkov formalism of superconductivity to calculate the response function of superfluid gas due to stimulated light scattering taking into account the final state interactions. The polarization of light has been shown to play a significant role in response of ...
متن کاملScattering of short laser pulses from trapped fermions
Rapid advances of trapping and cooling of alkali atoms [1] have led to the recent dramatic achievement of BoseEinstein condensation (BEC) of these trapped atoms [2–5]. Focusing these highly successful trapping and cooling methods onto fermions instead of bosons offers additional rich opportunities for studying degenerate fermionic atomic gases. The description of these magnetically trapped Ferm...
متن کاملHigh Temperature Superfluid and Feshbach Resonance
We study an effective field theory describing cold fermionic atoms near a Feshbach resonance. The theory gives a unique description of the dynamics in the limit that the energy of the Feshbach resonance is tuned to be twice that of the Fermi surface. We show that in this limit the zero temperature superfluid condensate is of order the Fermi energy, and obtain a critical temperature TC ≃ 0.43 TF...
متن کاملCooper pair coherence in a superfluid Fermi gas of atoms
We study the coherence properties of a trapped two-component gas of fermionic atoms below the BCS critical temperature. We propose an optical method to investigate the Cooper pair coherence across different regions of the superfluid. Near-resonant laser light is used to induce transitions between the two coupled hyperfine states. The beam is split so that it probes two spatially separate region...
متن کاملLaser probing of Cooper-paired trapped atoms
We consider a gas of trapped Cooper-paired fermionic atoms that are manipulated by laser light. The laser induces a transition from an internal state with large negative scattering length ~superfluid! to one with weaker interactions ~normal gas!. We show that the process can be used to detect the presence of the superconducting order parameter. Also, we propose a direct way of measuring the siz...
