Within this framework, the quark--antiquark potential is extracted from the classical configuration of a fundamental string, allowing for a direct analysis of vacuum instability and pair production. In the absence of a magnetic field, the step dilaton leads to a significantly sharper suppression of the potential barrier as the electric field increases, im"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"the step dilaton background exhibits a substantially stronger response of the Schwinger effect to external electromagnetic fields than conventional soft-wall models, providing a novel mechanism for controlling pair production","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"that the chosen step dilaton profile constitutes a physically relevant and qualitatively distinct realization of confinement whose predictions remain stable under small deformations of the background","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"A step dilaton background in holography yields sharper suppression of the pair-production barrier and greater sensitivity of the Schwinger effect to electric and magnetic fields than conventional soft-wall models.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"A step dilaton background in holography causes the Schwinger effect to respond more strongly to electromagnetic fields than conventional soft-wall models.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"96287601a3644120d03cd385df611327849670ce4901759b0efc569a94d65246"},"source":{"id":"2604.17743","kind":"arxiv","version":2},"verdict":{"id":"1fb23d0c-5319-4321-98d9-1c1d70847328","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-10T04:57:19.603690Z","strongest_claim":"the step dilaton background exhibits a substantially stronger response of the Schwinger effect to external electromagnetic fields than conventional soft-wall models, providing a novel mechanism for controlling pair production","one_line_summary":"A step dilaton background in holography yields sharper suppression of the pair-production barrier and greater sensitivity of the Schwinger effect to electric and magnetic fields than conventional soft-wall models.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"that the chosen step dilaton profile constitutes a physically relevant and qualitatively distinct realization of confinement whose predictions remain stable under small deformations of the background","pith_extraction_headline":"A step dilaton background in holography causes the Schwinger effect to respond more strongly to electromagnetic fields than conventional soft-wall models."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2604.17743/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":20,"sample":[{"doi":"","year":1998,"title":"The Large N Limit of Superconformal Field Theories and Supergravity","work_id":"d6d2272a-c223-471a-bbbf-bfe4ee6a8ff3","ref_index":1,"cited_arxiv_id":"hep-th/9711200","is_internal_anchor":true},{"doi":"","year":2006,"title":"Linear Confinement and AdS/QCD","work_id":"70597318-3fde-4ce5-9c9a-80058d30e131","ref_index":2,"cited_arxiv_id":"hep-ph/0602229","is_internal_anchor":false},{"doi":"","year":2015,"title":"A Soft-Wall Dilaton","work_id":"8d1478b2-0235-44eb-9cae-54dbeda303e3","ref_index":3,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2013,"title":"Dynamical holographic QCD model for glueball and light meson spectra","work_id":"87fcd81f-4af7-4b61-a4b4-a55c22093d5a","ref_index":4,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2011,"title":"Holographic Schwinger Effect","work_id":"2e5f040a-e560-465e-afcc-87e6e70025eb","ref_index":5,"cited_arxiv_id":"","is_internal_anchor":false}],"resolved_work":20,"snapshot_sha256":"71211c576588661bc3c7f7fd00cba359d326e259c5ae546899fc73ad88bd7571","internal_anchors":2},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
