Universal spectrum of isolated three-body resonances
Ludovic Pricoupenko
The exact wavefunction of an isolated three-body resonance at finite scattering length is obtained for two identical particles interacting with another one via a pairwise zero-rang…
General features and contact modeling of -body isolated resonances near threshold
Ludovic Pricoupenko
-body non efimovian bound or quasi-bound states for particles with short range interactions are considered in arbitrary dimensions. The different resonance regimes near the thre…
Universality of isolated -body resonances at large scattering length
Ludovic Pricoupenko
Non Efimovian -body resonances are investigated in the regime of a large two-body s wave scattering length. In view of a universal description of low-energy bound and quasi-boun…
Shallow Trimers of Two Identical Fermions and One Particle in Resonant Regimes
Pascal Naidon, Ludovic Pricoupenko, Christiane Schmickler
We consider two identical fermions interacting in the p-wave channel. Each fermion also interacts with another particle in the vicinity of an s-wave resonance. We find that in addi…
Width and shift of Fano-Feshbach resonances for van der Waals interactions
Pascal Naidon, Ludovic Pricoupenko
We revisit the basic properties of Fano-Feshbach resonances in two-body systems with van der Waals tail interactions, such as ultracold neutral atoms. Using a two-channel model and…
The three-body pseudo-potential for atoms confined in one dimension
Ludovic Pricoupenko
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 ul…
