Towards stable, strongly dipolar mixtures of ultracold dysprosium atoms — •Marian Dürbeck, Lennard Reihs, Johannes Seifert, Bala Choudhari, Juan Pablo Marulanda Serna, Nelson Werum, Marco De Pas, Gerard Meijer, and Giacomo Valtolina — Fritz-Haber-Institut der Max-Planck-Gesellschaft, Faradayweg 4-6, 14195 Berlin

Quantum gases of magnetic atoms, such as dysprosium (Dy), have recently enabled the realization of the long-sought-after supersolid phase. More exotic regimes of supersolidity have been 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 simultaneously slowing and trapping different isotopes of Dy and discuss progress in creating strongly dipolar Bose-Bose mixtures.
