Few-Boson Processes in the Presence of an Attractive Impurity under One-Dimensional Confinement
Nirav P. Mehta ; Connor D. Morehead ;
Date 1 Aug 2015
AbstractWe consider a few-boson system confined to one dimension with a single distinguishable particle of lesser mass. All particle interactions are modeled with $delta$-functions, but due to the mass imbalance the problem is nonintegrable. Universal few-body binding energies, atom-dimer and atom-trimer scattering lengths are all calculated in terms of two parameters, namely the mass ratio: $m_{ ext{L}}/m_{ ext{H}}$, and ratio $g_{ ext{HH}}/g_{ ext{HL}}$ of the $delta$-function couplings. We specifically identify the values of these ratios for which the atom-dimer or atom-trimer scattering lengths vanish or diverge. We identify regions in this parameter space in which various few-body inelastic process become energetically allowed. In the Tonks-Girardeau limit ($g_{ ext{HH}} ightarrow infty$), our results are relevant to experiments involving trapped fermions with an impurity atom.
