mysterious. In addition to traditional dark matter searches which usually involve large detectors, methods and devices developed for quantum technologies can help the hunt for various
hypothetical particles with tabletop experiments. Two recent studies report more stringent constraints on dark matter from experiments with atoms and ions. The experiment uses a mixture of
dense spin-polarized 129Xe gas, which might interact with ALPs leading to an unexpected magnetic field, and 85Rb vapour, which serves as an in-situ magnetometer. The 85Rb vapour is
magnetically driven by a strong time-modulated (Floquet) field to enhance the sensitivity of the magnetometer, leading to tighter constraints in the dark matter particle mass range and
improved limits on the coupling between ALPs and neutrons. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Access Nature
