A Pure Confinement Induced Trimer in One-Dimensional Atomic Waveguides
arXiv:1803.07783 · doi:10.1103/PhysRevA.97.061604
Abstract
Shallow trimers composed of three bosonic atoms in one-dimensional harmonic waveguides are studied in the vicinity of a Feshbach resonance. It is shown that for arbitrarily large values of the one-dimensional scattering length, an excited trimer branch exists in coexistence with the dimer and the trimer of the Lieb-Liniger model.
