Toward subradiant chains of individually trapped dysprosium atoms

Collective radiation modes in ensembles of atoms promise exciting applications to future quantum technologies. In particular, subradiance - where collective emission occurs significantly slower than spontaneous emission - could prove useful for controlling light, and is possible when the interatomic distance d < λ/2 (the wavelength of the emitted light). Additionally, interest in using lanthanides such as dysprosium (Dy) to investigate quantum systems has grown considerably in recent years, due in part to their rich electronic structure. Many of these atoms offer a range of linewidths for optical transitions allowing for a highly flexible control of systems of lanthanides. In this work, we report on progress in the building of an experimental setup to create arrays of single Dy atoms in optical tweezers taking advantage of Dy's rich level structure.
