Abstract
Magnetic levitation technology offers force sensitivities at the quantum frontier, making it a promising platform for probing the feeble interactions predicted by physics beyond the Standard Model. Despite this promise, the case for magnetic levitation in fundamental physics is only beginning to be built. In this talk, I will present the first searches for dark matter using magnetic levitation technology. I will begin with the hunt for ultralight dark matter---a wavelike dark matter candidate that induces oscillatory signatures in our detector. Focusing on vector dark matter stemming from a broken U(1)B-L symmetry, I will show how our experiment can be optimised to achieve sensitivities two orders of magnitude beyond the currently leading fifth-force constraints for masses m_DM = 10-13 eV. I will then present preliminary results from a dedicated search for ultraheavy dark matter, targeting instead the minuscule impulses generated by passing dark matter particles. We obtain leading limits for masses around m_DM = 107 GeV, surpassing those recently achieved by optical levitation strategies. Together, our results open a new experimental window into the search for dark matter and showcase the potential of magnetic levitation as a precision probe of fundamental physics. |
