Abstract: I will present a new opportunity for sub-GeV dark matter (DM) detection using large-volume neutrino detectors. DM-electron scattering in an observatory can excite or ionize target molecules, which then produce light that can be detected by the photomultiplier tubes (PMTs). While individual DM scatterings are undetectable, the aggregate rate from many independent scatterings can be isolated from the total PMT dark rate using the expected DM annual modulation. This search can be employed in multiple existing and upcoming experiments, with sensitivity in some mass ranges that exceeds all other techniques and reaches key particle-theory benchmarks.
