Sub-GeV dark matter detection with quantum sensors
Dark matter lighter than a proton would deposit far too little energy to detect by knocking atoms, so new detectors aim to sense single vibrations of a crystal (phonons), single spin waves (magnons) or single electrons. The questions are which of these detectors can work and whether favored models of light dark matter are already ruled out.
Why it matters
Light dark matter is a large, testable region of parameter space that conventional detectors cannot reach, and probing it depends on detection methods borrowed from condensed matter and quantum devices.
