Study of matter-wave superradiance in a dipolar Erbium BEC

POSTER

Abstract

Lanthanide atoms such as dysprosium and erbium have attracted significant attention in quantum

simulation due to their large magnetic moment and rich internal structure. In this poster, we present

our new versatile apparatus that efficiently produces a dipolar erbium quantum gas and discuss

several experimental tools developed in recent years, ranging from the two-stage slowing to the

active stabilization scheme for a diode laser system. Using this new apparatus, we recently study

a matter-wave superradiance process in a dipolar Bose gas of erbium-168 atoms. We will present

detailed experimental analysis of the superradiance when the external magnetic field breaks the

symmetry.
