Interspecies interactions in an ultracold dipolar mixture

Abstract

The authors theoretically and experimentally investigate the influence of the dipole-dipole interactions on the total interspecies interaction in an ultracold erbium-dysprosium mixture. The dipole-dipole interactions are tuned by rotating the dipole orientation and tracing the in-trap displacement between the species. As a result, the authors provide a lower and upper bound for the interspecies scattering length.
