The Casimir energy is computed for an arbitrary number of dimensions using the Abel-Plana formula, while the one-loop instanton functional determinant is evaluated using the Green's functions for the fluctuation operators. The resulting energetic properties are non-trivial: both the Casimir effect and tunnelling contribute to the Null Energy Condition violation, arising from a non-extensive true v","authors_text":"Bjorn Garbrecht, Jean Alexandre, Matthias Carosi, Silvia Pla, Wen-Yuan Ai","cross_cats":["astro-ph.CO","gr-qc","hep-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-th","submitted_at":"2024-02-15T10:34:45Z","title":"Double-well instantons in finite volume"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2402.09863","kind":"arxiv","version":2},"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:d33ba82b6d8894e5b23e7a5dbed235e3df2f064a3ddfa7e5e33becd0924e0ac9","target":"record","created_at":"2026-07-05T08:20:10Z","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":"98fb04cfd6ee96b2577e745cac39dbfc9430f42a19e41681a35b9a268ec293ed","cross_cats_sorted":["astro-ph.CO","gr-qc","hep-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-th","submitted_at":"2024-02-15T10:34:45Z","title_canon_sha256":"1d92ee8a2abaae8bf79f12833a3e2eabcc306a903ff3fe2a683aa43c9f8e6268"},"schema_version":"1.0","source":{"id":"2402.09863","kind":"arxiv","version":2}},"canonical_sha256":"1987a59f43a579963cc8c6371a0e15e837470927d89e33890f573c1cd2640b1c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1987a59f43a579963cc8c6371a0e15e837470927d89e33890f573c1cd2640b1c","first_computed_at":"2026-07-05T08:20:10.232117Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:20:10.232117Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RqtTV2DbIs7RU4/Hic2NSEzIBqUKTA43GfS4TFADo6RNFBcl9V9sGs5aYBZk4gFuoDCvXR+Ew/HQJUhVZ0LXAw==","signature_status":"signed_v1","signed_at":"2026-07-05T08:20:10.232592Z","signed_message":"canonical_sha256_bytes"},"source_id":"2402.09863","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d33ba82b6d8894e5b23e7a5dbed235e3df2f064a3ddfa7e5e33becd0924e0ac9","sha256:1697f0c14fbc93c5e62bf6197a384c4470445a70fb8681ab963cb66a19591e87"],"state_sha256":"01e4268fc845e6329b0fc3ead3de483cee83188cb1465b45abed1e7cd550ee79"}
