The new feature is that this decay rate is found in the context of non thermal scalar fields in contact with a thermal bath of photons. In general, to make topologically unstable strings stable, one can couple them to such a bath. The resulting plasma effect creates metastable configurations which can decay from the false vacuum to the true vacuum. In our specific set-up, the instanton computation is realized for the case of two out-of-equilibrium complex scalar fields : on","authors_text":"Johanna Karouby","cross_cats":["astro-ph.CO","gr-qc","hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-12-07T21:12:17Z","title":"String melting in a photon bath"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.1723","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":"sha256:9f4d1d356366851975e9c72d99ca004cac9c539bd54fbe839adb51b66db288ab","target":"record","created_at":"2026-05-18T01:52:46Z","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":"ce73a77fd1a5af9cb24a47d7d8bff618da3c8840b81b47e53a0f4076b7349a39","cross_cats_sorted":["astro-ph.CO","gr-qc","hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-12-07T21:12:17Z","title_canon_sha256":"1957cf09966145082ef23681afacef8e501e77631b4c48cf7b129c379f7341e0"},"schema_version":"1.0","source":{"id":"1212.1723","kind":"arxiv","version":3}},"canonical_sha256":"3c819918199be9c1704c66296533b633a0360c234e20ed97c1c86959bf4e982f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3c819918199be9c1704c66296533b633a0360c234e20ed97c1c86959bf4e982f","first_computed_at":"2026-05-18T01:52:46.334512Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:52:46.334512Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FMMlyju1Dd+fYMQv7+09lfrqhVE9if2U6agIbtYg+U2dM9lo/U6dfZEk/w3jnF+lrWaVjjJq0fbbWQjWYilSAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:52:46.335072Z","signed_message":"canonical_sha256_bytes"},"source_id":"1212.1723","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9f4d1d356366851975e9c72d99ca004cac9c539bd54fbe839adb51b66db288ab","sha256:e71bc80590fbac26123f4d5bd9d1cc44b30210eb9cd133999bf92bbb287886bf"],"state_sha256":"19e647ba88987c29d1b9524bbccf5a2342a164b99a40f3b4162ebfe02b2c01e0"}
