Experimental setup for the production of ultracold strongly correlated fermionic superfluids of \(^{6}\)Li

We present our experimental setup to produce ultracold strongly correlated fermionic superfluids made of a two-component spin-mixture of \(^6\)Li atoms. Employing standard cooling techniques, we achieve quantum degeneracy in a single-beam optical dipole trap. Our setup is capable of generating spin-...

Description
Summary:We present our experimental setup to produce ultracold strongly correlated fermionic superfluids made of a two-component spin-mixture of \(^6\)Li atoms. Employing standard cooling techniques, we achieve quantum degeneracy in a single-beam optical dipole trap. Our setup is capable of generating spin-balanced samples at temperatures as low as \(T/T_F = 0.1\) containing up to \(5 \times 10^4\) atomic pairs. We can access different superfluid regimes by tuning the interparticle interactions close to a broad magnetic Feshbach resonance. In particular, we are able to explore the crossover from the molecular Bose-Einstein condensate (BEC) to the Bardeen-Cooper-Schrieffer (BCS) superfluid regimes.
