Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

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

Experiments have lagged theory in exploring chemical interactions at temperatures so low
that translational degrees of freedom can no longer be treated classically. The difficulty has …

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 …

Interactions between particles can be strongly altered by their environment. We demonstrate
a technique for modifying interactions between ultracold atoms by dressing the bare atomic …

We study atom scattering from two colliding Bose-Einstein condensates using a position
sensitive, time resolved, single atom detector. In analogy to quantum optics, the process can …

We study the horizontal transport of ultracold atoms over macroscopic distances of up to 20
cm with a moving 1D optical lattice. By using an optical Bessel beam to form the optical …

Cold atomic clouds and Bose-Einstein condensates have been stored in a 10 cm diameter
vertically oriented magnetic ring. An azimuthal magnetic field enables low-loss propagation …

The close theoretical analogy between the physics of rapidly rotating atomic Bose
condensates and the quantum Hall effect (ie a two-dimensional electron gas in a strong …

We study the widths of interspecies Feshbach resonances in a mixture of the fermionic
quantum gases Li 6 and K 40. We develop a model to calculate the width and position of all …
