Repeated absorption-emission-processes of photons on dye molecules here establish a thermal coupling of the photonic quantum gas to both a heat bath and a particle reservoir comprised of dye molecules. In this way, for the first time Bose-Einstein condensation under grand-canonical statistical ensemble conditions becomes experimentally accessible.","authors_text":"Julian Schmitt","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2018-07-23T17:55:10Z","title":"Dynamics and correlations of a Bose-Einstein condensate of photons"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.08747","kind":"arxiv","version":1},"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:e54e64dca3c5d7e8451320643ee29ff384c4f5de87adfd96a87b16ecbffd89aa","target":"record","created_at":"2026-05-18T00:10:04Z","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":"0ee7aafd01b0e6344db4b4985fd65e90747a86166fff776adb0406b24b4504ba","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2018-07-23T17:55:10Z","title_canon_sha256":"80976266cce779abefbdcaf00e09dfb2f0b0fb395fb0eb78e6c0105d13cccacc"},"schema_version":"1.0","source":{"id":"1807.08747","kind":"arxiv","version":1}},"canonical_sha256":"4da136eac213c82a98a7a8a613d3cd69b77454f6df002d9da49dc8dae8e28f2b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4da136eac213c82a98a7a8a613d3cd69b77454f6df002d9da49dc8dae8e28f2b","first_computed_at":"2026-05-18T00:10:04.829650Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:10:04.829650Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6p5kLqXNfELtlkR6wu+zGQ1bvzEbAYfcWtwJ5Qp/UMY5l3+rcAfUmPsWUhSoAWzzfqXLRa2EAynmCZcrQqb7DA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:10:04.830481Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.08747","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e54e64dca3c5d7e8451320643ee29ff384c4f5de87adfd96a87b16ecbffd89aa","sha256:b1100a1161c3a77cd3f7d1b1dee8340ff52cffda4b950983f2c559895c69f0ec"],"state_sha256":"5fb35fa35d19f10e85eb3eddcc4a13b9c28d887bb334595bcf50bc19b0ef325d"}
