Photons develop an effective mass in the medium thus -- as a result of the finite chemical potential -- a photon Bose-Einstein condensation can be achieved by adjusting one of the relevant parameters (temperature, photon density and plasma density) to criticality. Due to the presence of the plasma, Planck's law of blackbody radiation is also modified with the appearance of a gap below the plasma frequency where a condensation peak of coherent radiation arises for the critical system.","authors_text":"Peter Mati","cross_cats":["cond-mat.quant-gas","physics.plasm-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2019-02-21T12:19:57Z","title":"Statistical theory of photon gas in plasma"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.07998","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:76b6ff9c8d412d0417afead78e72c5d41ce1a87e0ca9187ecd8647497a3926cd","target":"record","created_at":"2026-07-05T00:56:23Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"802a330cc87ef8ccfec410ae326e243570dd7b50d06e67eb595ac23aa2cd4f36","cross_cats_sorted":["cond-mat.quant-gas","physics.plasm-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2019-02-21T12:19:57Z","title_canon_sha256":"cca77c3aed426f24350ee59bad35e9f8477174b3fac8731673b6fe61cca1c24e"},"schema_version":"1.0","source":{"id":"1902.07998","kind":"arxiv","version":3}},"canonical_sha256":"7ee4e8778681c50ceb0ced32bace8762e6b67eebd6ffdbe86fa58d0ecba03a17","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7ee4e8778681c50ceb0ced32bace8762e6b67eebd6ffdbe86fa58d0ecba03a17","first_computed_at":"2026-07-05T00:56:23.866907Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:56:23.866907Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Gt+qyYN1CX3nkht55NJ+G9pbHqLGtC0hhhbZPHJ7Xaba5Hc2sK275doi+Scn7F064whx0DSHzog3DTZXlGH1Aw==","signature_status":"signed_v1","signed_at":"2026-07-05T00:56:23.867253Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.07998","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:76b6ff9c8d412d0417afead78e72c5d41ce1a87e0ca9187ecd8647497a3926cd","sha256:b2b829bd955d23a486e3800390afe597640c733f6d2dcb834c8748882d630458"],"state_sha256":"ed34b3e8b759dbbd5bc723ed9b2d6b4d0c0c5fd6a0c3e6c4da9ad26c6ce7c3f5"}
