Higher-order effective interactions for bosons near a two-body zero crossing
A. Pricoupenko, D. S. Petrov
We develop the perturbation theory for bosons interacting via a two-body potential of vanishing mean value. We find that the leading nonpairwise contribution to the energy emer…

Three-body interaction near a narrow two-body zero crossing
A. Pricoupenko, D. S. Petrov
We calculate the effective three-body force for bosons interacting with each other by a two-body potential tuned to a narrow zero crossing in any dimension. We use the standard two…

One-dimensional three-boson problem with two- and three-body interactions
G. Guijarro, A. Pricoupenko, G. E. Astrakharchik +2
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 us…
