Superfluid transition temperature in a trapped gas of Fermi atoms with a Feshbach resonance

Superfluid transition temperature in a trapped gas of Fermi atoms with a Feshbach resonance

We investigate strong-coupling effects on the superfluid phase transition in a gas of Fermi atoms with a Feshbach resonance. The Feshbach resonance describes a composite quasiboson that can give rise to an additional pairing interaction between the Fermi atoms. This attractive interaction becomes stronger as the threshold energy $2\ensuremath{\nu}$ of …
