Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

The capability to tune the strength of the elastic interparticle interaction is crucial for many
experiments with ultracold gases. Magnetic Feshbach resonances, are widely harnessed for …

The recent developments of microgravity experiments with ultracold atoms have produced a
relevant boost in the study of shell-shaped ellipsoidal Bose-Einstein condensates. For …

The problem of spin squeezing with a bimodal condensate in the presence of particle losses
is solved analytically by the Monte Carlo wave function method. We find the largest …

We resolve the unexpected and long-standing disagreement between experiment and
theory in the Efimovian three-body spectrum of Li 7, commonly referred to as the lithium few …

We present precision measurements with MHz uncertainty of the energy gap between
asymptotic and well bound levels in the electronic ground state X Σ 1 g+ of the K 39 2 …

We study the three-body problem for three atomic fermions, in the same spin state,
experiencing a resonant interaction in the p-wave channel via a Feshbach resonance …

Since the early days of quantum physics, the complex behavior of three interacting particles
has been the subject of numerous experimental and theoretical studies. In a recent Letter to …

The He 3 4 system is studied using the adiabatic hyperspherical representation. We adopt
the current state-of-the-art helium interaction potential including retardation and the …

We discuss several issues important for experimentally observing Efimov physics in
ultracold quantum gases. By numerically solving the three-boson Schrödinger equation over …
