Our research focuses on the development of optical clocks using ultracold atomic systems. By tightly confining ytterbium in the ideal potential of a magic-wavelength optical lattice, the lattice clock ...

(via Sabine Hossenfelder) In 2020, a group of MIT researchers detected an anomaly in the nuclei of ytterbium atoms. They said that the nuclei’s strange behavior might be indicative of a “dark force” ...
