Towards Bose-Einstein condensation of strongly dipolar mixtures of dysprosium atoms — Lennard Reihs, Marian Duerbeck, Johannes Seifert, Bhalchandra Choudhari, Juan Pablo Marulanda, Nelson Werum, Marco De Pas, Gerard Meijer, and •Giacomo Valtolina — Fritz-Haber-Institut der Max-Planck-Gesellschaft, Faradayweg 4-6, 14195 Berlin, Germany

Quantum gases of magnetic atoms, such as dysprosium (Dy), can provide access to a wide range of exotic many-body physics. Prominently, this included the recent realization of the long-sought-after supersolid phase. A richer landscape of supersolid phases has been theoretically predicted for mixtures of these magnetic atoms. We report on our efforts to create stable mixtures of Dy. We show a broadly applicable frequency-modulation scheme for simultaneous slowing and trapping of different isotopes of Dy and discuss progress toward producing mixtures of strongly dipolar Bose-Einstein condensates.
