Anisotropy in the Interaction of Ultracold Dysprosium

Understand

The nature of the interaction between ultracold atoms with a large orbital and spin angular momentum has attracted considerable attention.

• It was suggested that such interactions can lead to the realization of exotic states of highly correlated matter.
• Here, we report on a theoretical study of the competing anisotropic dispersion, magnetic dipole-dipole, and electric quadrupole-quadrupole forces between two dysprosium atoms.
• Each dysprosium atom has an orbital angular momentum L=6 and magnetic moment $\mu=10\mu_B$.
