Description
The direct detection of light (sub-MeV) dark matter presents a significant challenge due to the need for sub-eV energy thresholds. I will discuss a new proposal to use a superfluid helium optomechanical cavity to search for dark matter in the keV mass range. In this regime, dark matter scattering excites a single phonon in the superfluid helium target. Optomechanical systems have demonstrated sensitivity to individual phonons with meV energies, making them ideally suited to the detection of light dark matter.
