Production of large ${}^{41}$K Bose-Einstein condensates using D1 gray molasses

Hao-Ze Chen, Xing-Can Yao, Yu-Ping Wu +5

We use D1 gray molasses to achieve Bose-Einstein condensation of a large number of ${}^{41}$K atoms in an optical dipole trap. By combining a new configuration of compressed-MOT with…
