Efficient production of Bose-Einstein Condensates of<sup>168</sup>Er
POSTER
Abstract
Lanthanide atoms such as dysprosium and erbium have attracted significant attention in quantum simulation with ultracold atoms due to their large magnetic moment and richness of Feshbach resonances. In this poster, we will demonstrate the production of Bose-Einstein Condensates of 168Er atoms in a new apparatus. By using the technique of two-stage slowing, we improve the loading efficiency into the magneto-optical trap (MOT) and operate a narrow-line MOT , followed by the forced evaporative cooling in a crossed optical dipole trap. The efficient production of ultracold Er atoms allows us to explore unprecedented quantum phenomena with dipolar interactions. We will also discuss our recent experimental progress.
