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.

Three-body pseudopotential for atoms confined in one dimension
Following a strong analogy with two-dimensional physics, the three-body pseudo-potential in one dimension is derived. The Born approximation is then considered in the context of ultracold atoms in a

Anomalous frequency shifts in a one-dimensional trapped Bose gas
We consider a system of interacting bosons in one dimension at a two-body resonance. This system, which is weakly interacting, is known to give rise to effective three-particle interactions, whose

We solve the three-boson problem with contact two- and three-body interactions in one dimension and analytically calculate the ground and excited trimer-state energies. Then, by using the diffusion


Breakdown of integrability in a quasi-1D ultracold bosonic gas.
We demonstrate that virtual excitations of higher radial modes in an atomic Bose gas in a tightly confining waveguide result in effective three-body collisions that violate integrability in this

Three-boson problem near a narrow Feshbach resonance.
This work considers a three-boson system with resonant binary interactions and shows that for sufficiently narrow resonances three- body observables depend only on the resonance width and the scattering length, revealing novel physics of three-body collisions.
