It is unclear whether photochemistry can be changed when nearly all excitations end up in dark states.","posed_since":"","precise":"For $N$ organic emitters under electronic strong coupling with a cavity mode, with reorganization energy $\\lambda$ and static energetic disorder $\\sigma$, compute the photoreaction quantum yield (for example photoisomerization) after excitation of the lower polariton, accounting for relaxation into the $N-1$ dark states. The answer is whether, and in what range of $\\lambda$, $\\sigma$ and Rabi splitting, the yield differs from the cavity-free value by more than 10 percent.","problem_ref":null,"references":"","settled_by":"Large-N simulations of polariton relaxation and reaction dynamics validated against cavity photoisomerization experiments.","status_note":"","title":"Effect of dark states on cavity-modified photochemistry","topic_ref":"a1800d58731adf7edb05cc3f1a2db4d47371dec4cc339e0c64df5cda73c94331"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"a90bd6663cbf5abec97f0432452da3a9d0dca08f8e38ba51896680250bc2c1c8","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"0707e5022d9b4016f64b5ccaacfbd9e52505490d2d18a7cf4a0e0030d63c01bd","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"VLcUXbYDEBSMzLJRx_7NgMcUQRnzWP8Yc0Trr5a3BGyk4odhmibCaVhoTiKAJREkdTx7-0NeOcm0xacjEokpAg"},"schema":"pubphys.envelope/1"},"record_hash":"a90bd6663cbf5abec97f0432452da3a9d0dca08f8e38ba51896680250bc2c1c8","leaf_index":884}
