Loss features in ultracold 162Dy gases: two- versus three-body processes
We quantitatively investigate the low-field (B<6G) loss features in ultracold thermal samples of 162Dy, revealing two- and three-body dominated loss processes. We investigate their temperature dependence and detect a feature compatible with a d-wave Fano-Feshbach resonance, which has not been observed before. We also analyse the expansion of the dipolar Bose-Einstein condensate as a function of the magnetic field and interpret the changes in size close to the resonances with a variation in the scattering length.
