We aim to widen the range of quantum simulations with cold atoms, by investigating phenomena arising from the long-ranged dipolar interaction in reduced dimensionalities. We are operating a new experimental setup based on quantum gases of the highly magnetic Dysprosium atoms. This is a joint project between LENS and CNR-INO, Sezione di Pisa.

Broad Feshbach resonances in Dysprosium atoms

We have characterized the scattering properties of ultracold 162Dy atoms for magnetic fields between 6 and 30 G. In addition to the typical chaotic distribution of narrow Feshbach resonances in Lanthanides, we have discovered two rather isolated broad features. A characterization using the complementary measurements of losses, thermalization, anisotropic expansion and molecular binding energy points towards resonances of predominant s-wave character, with dimensionless strength s=0.5(3). Such resonances will ease the investigation of quantum phenomena relying on the interplay between dipole and contact interactions.
