Optically trapped nanosphere arrays could detect nuclear recoils from solar ALPs, sub-keV pseudoscalar/vector dark matter, and Earth-bound dark matter, opening new tabletop search windows in previously unconstrained parameter space.

abstract
Motivated by the current interest in employing quantum sensors on Earth and in space to conduct searches for new physics, we provide a perspective on the suitability of large-mass levitated optomechanical systems for observing dark matter signatures. We discuss conservative approaches of recoil detection through spectral analysis of coherently scattered light, enhancements of directional effects due to cross-correlation spectral densities, and the possibility of using quantum superpositions of mesoscopic test particles to measure rare events.
