The difference of the boundary conditions on the solutions of the field equation is discussed to result in the effective action both in the Coulomb and time-dependent gauge. Finally, the apparent spin-statistics inversion is also discussed, where the WKB action for bosons (fermions) works well for fermion (boson) pair-production rate.","authors_text":"Sang Pyo Kim (Kunsan Natl Univ.)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2009-02-19T23:57:38Z","title":"Effective Action and Schwinger Pair Production in Strong QED"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0902.3486","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":"sha256:4981bca634f90f61aaccd45b905db82c1ab5367750b0931b0b3df398397f6b6b","target":"record","created_at":"2026-05-18T02:14:46Z","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":"02e86f1e087fd56a8202c0db9da28afdc5295d9eb16dbeb5dde009666ebf6f7a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2009-02-19T23:57:38Z","title_canon_sha256":"3b3eb444bb9f6f869e6d12fd325d190b8f5ec9dec16da626966babe8075b0db1"},"schema_version":"1.0","source":{"id":"0902.3486","kind":"arxiv","version":2}},"canonical_sha256":"a9e5bf931da37b42fd037e72e0f85c56e9e1b890d1381434c792a6bef11c60b9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a9e5bf931da37b42fd037e72e0f85c56e9e1b890d1381434c792a6bef11c60b9","first_computed_at":"2026-05-18T02:14:46.799506Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:14:46.799506Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ewQjJwuQCZ7E25VRSRKLJCS37Azt3gI6KxYm1pMl1cUYVxAphKrF9q6j+txmmw2/bKXe33xzX3X3p8vZY6cEAA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:14:46.800022Z","signed_message":"canonical_sha256_bytes"},"source_id":"0902.3486","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4981bca634f90f61aaccd45b905db82c1ab5367750b0931b0b3df398397f6b6b","sha256:8482bb8d66235680970119573e409fc0847db8641bef5a21253c371d63cfb65e"],"state_sha256":"218ad3efbfb6352d8a96b5bf8eca7d29cbce69586a56b5017b04c781545a20e9"}
