| Abstract: Optomechanical sensors have seen recent innovations which make them more useful as leading detectors of ultralight dark matter. To date they remain a less-studied class of detectors among the rapidly developing field of quantum sensors, and a full study of the potential of these sensors to detect scalar, pseudoscalar and vector DM coupling is lacking. After giving the necessary background knowledge to calculate their sensitivity, I will give some new insights into optimisation of these systems for DM detection and propose a new detector which can lead to new bounds on DM couplings, focusing on B-L vector DM as an illustration. This new setup, proposed in collaboration with experimentalists, is easily feasible with current technologies, and will operate at the standard quantum limit (SQL). Finally I will briefly discuss the prospects of improving on these bounds by reaching SQL on resonance and other exciting near-future prospects. |
