Description
The direct detection of light (sub-MeV) dark matter presents a significant challenge due to the need for very low energy thresholds. I will discuss the Optomechanical Dark-matter INstrument (ODIN), a new proposal to use a superfluid helium optomechanical cavity to search for dark matter in the keV mass range. Scattering dark matter excites a single (ueV range) phonon in the superfluid helium, which is then converted into an (eV range) photon via an optomechanical interaction with a pump laser. This photon can be efficiently detected, providing a means to sensitively probe keV scale dark matter. Optomechanical systems have demonstrated sensitivity to phonons with ueV energies, making them ideally suited to the detection of light dark matter.
