Polarized Fermi gases
Recently, two experiments, reported in Science[1, 2], have studied a polarized ultra-cold degenerate Fermi gas. This is a very new area that has attracted a great amount of interest from widely varying fields ranging from condensed matter physics, atomic molecular and optical physics, to particle and astro physics. As polarized Fermi gases have been demonstrated to be stable near the resonance,...
متن کاملTheory of ultracold Fermi gases
The physics of quantum degenerate Fermi gases in uniform as well as in harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is given to the effect of interactions which play a crucial role, bringing the gas into a superfluid phase at low temperature. In these dilute systems interactions are characterized by a single parameter, the s-wave scattering length, wh...

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 کاملUltra-cold Fermi gases
Molecule formation in ultracold degenerate quantum gases is one of the central topics in the overall ACQAO program, due to the strong quantum correlations in these systems. An experimental program in ultra-cold molecule formation using fermionic Li near a Feshbach resonance is underway at the SUT node of ACQAO. The work described here provides theoretical support for possible experimental inves...
