Light-induced correlations in cold dysprosium atoms — •Nivedith Anil, Marvin Proske, Ishan Varma, Dimitra Cristea, and Patrick Windpassinger — Institut für Physik, JGU Mainz

We intend to study light-matter interactions to explore the effect of magnet dipole-dipole interactions in highly dense samples of atoms exhibiting large permanent magnetic dipole moments. When the average interatomic distances are smaller than the wavelength of the scattering light, strong electric and magnetic dipole-dipole interactions give rise to collective light-scattering phenomena in the spectral and temporal domains. With the largest ground-state magnetic moment in the periodic table (10 Bohr-magneton), dysprosium is the perfect candidate for these experiments.

This poster reports on our progress in generating extremely dense ultracold atomic dysprosium clouds. We present our method to optically transport the atoms into a home-built science cell using a high-precision air-bearing translation stage. A custom-built high NA objective will re-trap the transported atoms in a tightly focussed microscopic optical dipole trap. Further, we discuss the design of a magnetic field system, which allows for highly precise magnetic field control and the ability to tune the contact interactions between the dysprosium atoms.
