The Fascination of Lanthanides for Ultracold Quantum Physics
Given their strong magnetic moment and exotic electronic configuration, lanthanide atomic species disclose a plethora of intriguing phenomena in ultracold quantum physics. The large magnetic moment of these atoms reflects on a strong interparticle dipole-dipole interaction, which has both a long-range nature and an isotropic character. Here, we report on our latest results on quantum many-body and few-body physics based on a strongly-magnetic lanthanide, erbium (Er). Particular emphasis will be given to the scattering properties of bosonic and fermionic Er, in which unconventional and fascinating phenomena appear as a result of both the magnetic and the orbital anisotropy of the underlying the native interactions between atoms.
