# Making two dysprosium atoms rotate —Einstein-de Haas effect revisited

@article{Gorecki2016MakingTD, title={Making two dysprosium atoms rotate —Einstein-de Haas effect revisited}, author={Wojciech G'orecki and Kazimierz Rzążewski}, journal={Europhysics Letters}, year={2016}, volume={116} }

We present a numerical study of the behaviour of two magnetic dipolar atoms trapped in a harmonic potential and exhibiting the standard Einstein-de Haas effect while subject to a time-dependent homogeneous magnetic field. Using a simplified description of the short-range interaction and the full expression for the dipole-dipole forces we show that under experimentally realisable conditions two dysprosium atoms may be pumped to a high 20)$ ?> value of the relative orbital angular momentum.

The first-principle coupled-channel calculation of the collisions between these spin-polarized bosonic dysprosium atoms reveals a strong interplay between the anisotropies in the dispersion and magnetic dipole-dipole interaction, and shows that both types of anisotropy significantly affect the Feshbach spectrum as a function of an external magnetic field.
