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

In this review, we discuss the properties of a few impurity atoms immersed in a gas of
ultracold fermions—the so-called Fermi polaron problem. On one hand, this many-body …

We report on the achievement of Bose-Einstein condensation of erbium atoms and on the
observation of magnetic Feshbach resonances at low magnetic fields. By means of …

We report on the Bose-Einstein condensation of more than 105 Li2 molecules in an optical
trap starting from a spin mixture of fermionic lithium atoms. During forced evaporative …

We observe collective oscillations of a trapped, degenerate Fermi gas of Li 6 atoms at a
magnetic field just above a Feshbach resonance, where the two-body physics does not …

The control of physical systems and their dynamics on the level of individual quanta
underpins both fundamental science and quantum technologies. Trapped atomic and …

We have converted an ultracold Fermi gas of L i 6 atoms into an ultracold gas of L i 2 6
molecules by adiabatic passage through a Feshbach resonance. Approximately 1.5× 10 5 …

This paper summarizes the experimental frontier of ultracold fermionic gases. It is based on
three lectures which one of the authors gave at the Varenna Summer School describing the …

A Fermi gas of atoms with resonant interactions is predicted to obey universal
hydrodynamics, in which the shear viscosity and other transport coefficients are universal …

We have measured ap-wave Feshbach resonance in a single-component, ultracold Fermi
gas of K 40 atoms. We have used this resonance to enhance the normally suppressed p …
