Quenched magneto-association of ultracold Feshbach molecules

We study enhanced magneto-association of atoms into weakly bound molecules near a Feshbach resonance using a quench preparatory stage. In anticipation of experiments with NASA's Cold Atom Laboratory aboard the International Space Station, we assume as a baseline a dual-species (^{87}\mathrm{Rb} \mathrm{and} ^{41}\mathrm{K})gas in a parameter regime enabled by a microgravity environment. It includes subnanokelvin temperatures and dual-species...
