The questions are which of these detectors can work and whether favored models of light dark matter are already ruled out.","title":"Sub-GeV dark matter detection with quantum sensors","topic_ref":null,"why":"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."},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"e60bc33f70ea44a1215dcfbe7831dd7817b64c21ad3c95ac918a82ec04971901","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"a8482df783e16f89401ee53eeb7c2c839c83717f6f248691c70a8eb8010cc068","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"ZUZvISt4nNp0JsHqZ5pBtLWUeLNNE-2Y-p4dt7wZx3hYI_dbp0OMQAJJ9aB3Fnh_SGUjqruT_BB0wNOje2esBw"},"schema":"pubphys.envelope/1"},"record_hash":"e60bc33f70ea44a1215dcfbe7831dd7817b64c21ad3c95ac918a82ec04971901","leaf_index":252}
