Abstract

Magnetic dipole-dipole interactions (MDDIs) are long-ranged and anisotropic. Among many other manifestations and specificities, they induce a coupling between spin and angular momentum degrees of freedom paving the way for new breakthroughs in the fields of quantum gas physics, magnetism and quantum information processing. Chromium, with its combination of relatively strong long-range and anisotropic MDDIs and simple isotropic short range interactions, stands as an appealing atom for the study of the unconventional spinor and magnetic properties of dipolar Fermi gases. Indeed, in comparison and despite stronger MDDIs, lanthanide atoms like Erbium and Dysprosium will present challenging issues related to the high density of Feshbach resonances and more generally to their anisotropic short range interactions.
