A versatile platform of dipolar Er BECs in an arbitrary potential
POSTER
Abstract
Magnetic atoms such as dysprosium and erbium have attracted significant attention due to the long range and anisotropic dipole-dipole interaction arising from the large magnetic moment. In this poster, we report the latest upgrade of our versatile apparatus towards a dipolar Bose-Einstein condensate (BEC) in an arbitrary programmable potential. Efficient production of dipolar BECs of $^{168}$Er and $^{166}$Er benefits from two-stage slowing followed by optical evaporative cooling. A dipolar BEC will then be adiabatically loaded into arbitrary potentials created by a spatial light modulator (SLM) with a high-resolution imaging system. We highlight how the dipolar system interplays with the special trap geometries.
