The question is whether they show the hallmark of a true spin glass.","posed_since":"","precise":"Transversely pumped atoms in a confocal multimode cavity realizing all-to-all couplings $J_{ij}$ with random signs (Sherrington-Kirkpatrick or Hopfield type). Measure the overlap distribution $P(q)$ between replicas (repeated preparations with the same $J_{ij}$) and determine whether it has continuous support (replica symmetry breaking) and whether it reflects equilibrium or a driven-dissipative steady state. The equilibrium Parisi solution is the comparison, not the question. Answer: $P(q)$ with an independent test of equilibration.","problem_ref":null,"references":"","settled_by":"Replica-overlap measurements across many disorder realizations with checks of fluctuation-dissipation relations.","status_note":"Replica symmetry breaking and an ultrametric overlap structure were observed in a driven-dissipative vector spin glass (Kroeze et al., Science 2025), and an Ising cavity spin glass was realized (Marsh et al., PRL 2025); the relation to equilibrium Parisi theory is open.","title":"Replica symmetry breaking in multimode-cavity spin glasses","topic_ref":"8df59b7655cdc4331866853909e22dff07fb2d661e37f2a43fdc664ddd9f7dda"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"0ae8172b7008b907a158061c1d3822359bcde5934b0a4b6b0307203a84c27863","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"cd3907ce7d945d330db87c363e83ad0b8307c3e8fd2ede4b7cba8d7acb6ab3dc","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"hGCYFbA6Xm9lVVDn8xfUEh5CqgaICnci3deMlb36Lta8rXd9Qq-4QP7_SKPLUkND_Pb13diZ22yQmoQDe691Dw"},"schema":"pubphys.envelope/1"},"record_hash":"0ae8172b7008b907a158061c1d3822359bcde5934b0a4b6b0307203a84c27863","leaf_index":383}
