We consider both the specious-confinement and deconfined phases. In the perpendicular magnetic field orientation, the strip length shows three distinct branches, and the entanglement entropy develops a swallow-tail structure, indicating a transition between connected and disconnected entanglement surfaces. For the parallel orientation, the behavior is monotonic and no transition occurs. In addition, the difference in entanglement entropy c"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Our findings show that entanglement entropy can serve as an effective probe of the QCD phase transition.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The Einstein-Maxwell-dilaton model with the chosen parameters faithfully reproduces the QCD phase diagram and its response to external magnetic fields.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Holographic entanglement entropy exhibits a swallow-tail structure indicating connected-to-disconnected transitions for perpendicular magnetic fields in the QCD phase diagram while remaining monotonic for parallel fields, consistent with black hole thermodynamics.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Entanglement entropy develops a swallow-tail structure under perpendicular magnetic fields, marking the QCD phase transition in a holographic model.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"270ac51776ec6ad794e3b65cba196f83e6145e306e2768352921c0ebc626a56f"},"source":{"id":"2605.17438","kind":"arxiv","version":1},"verdict":{"id":"ae8e14b4-2edb-4957-88e2-554341cb90f6","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-19T22:34:23.586568Z","strongest_claim":"Our findings show that entanglement entropy can serve as an effective probe of the QCD phase transition.","one_line_summary":"Holographic entanglement entropy exhibits a swallow-tail structure indicating connected-to-disconnected transitions for perpendicular magnetic fields in the QCD phase diagram while remaining monotonic for parallel fields, consistent with black hole thermodynamics.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The Einstein-Maxwell-dilaton model with the chosen parameters faithfully reproduces the QCD phase diagram and its response to external magnetic fields.","pith_extraction_headline":"Entanglement entropy develops a swallow-tail structure under perpendicular magnetic fields, marking the QCD phase transition in a holographic model."},"integrity":{"clean":false,"summary":{"advisory":1,"critical":0,"by_detector":{"doi_compliance":{"total":1,"advisory":1,"critical":0,"informational":0}},"informational":0},"endpoint":"/pith/2605.17438/integrity.json","findings":[{"note":"DOI in the printed bibliography is fragmented by whitespace or line breaks.
