Effects of 3-body resonances in ultracold bose gases

POSTER

Abstract

We are investigating the $3$--boson system using a model $2$--body potential capable of supporting bound states. Of particular interest is the atom--dimer scattering for large two-body scattering lengths (for example, in the vicinity of a Feshbach resonance). We study $3$--body effects in the context of a many body field theory accounting for correlations to the appropriate order. We are exploring the possibility of applying this to both homogeneous and optical lattice configurations in $^{85}$Rb. We acknowledge support for this project from the NSF.
