Current and next generation dark matter searches experiments  diverge in sensitivity for dark matter masses below a few GeV, leaving a valid and theory motivated sub-GeV mass range unreachable. The challenge is identifying single events of tens or hundreds of eV in a large bulk, and reducing accompanying backgrounds to satisfactory levels.

We are developinga new technology, based on finding single crystal defects in a bulk, that arise from interactions of light dark matter and a nucleus. These defects are long lived and spectroscopically active, which makes them ideal for detection of nuclear interactions with a threshold of tens of eV.
