Few-Boson Processes in the Presence of an Attractive Impurity under One-Dimensional Confinement | Nirav P. Mehta

1 Aug 2015 | Abstract: | We 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. | Source: | arXiv, 1508.0156 | Services: | Forum | Review | PDF | Favorites |
