Numerical methods for cold atom systems
… degenerate regimes in dilute ultracold atomic alkali-gases. In these dilute systems, interactions are characterized by a single parameter, the s-wave scattering length. In this dissertation, we review the physics of quantum degenerate atomic gases from a theoretical perspective and present the …

BEC-BCS crossover with Feshbach resonance for three-hyperfine-species model
… us to tune the effective interaction between alkali atoms. In a Feshbach resonance, the effective s-wave scattering length grows when one moves toward the resonance point, and eventually diverges at this point. There is one characteristic energy scale, $\delta_c$, defined as, in the negative …
