We show that there exists a Euclidean wormhole solution in this model by choosing a suitable shape of the dilaton potential. After the analytic continuation, this explains a quantum creation of a time-like traversable wormhole. Finally, we discuss relations to the information loss problem and the current literature.","authors_text":"Dong-han Yeom, Gansukh Tumurtushaa","cross_cats":["gr-qc"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-08-03T07:32:18Z","title":"Quantum creation of traversable wormholes ex nihilo in Gauss-Bonnet-dilaton gravity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.01103","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:a3af308f4336ef6880bca05f6913ac95246d5f131376502fc2e474192e82cb7e","target":"record","created_at":"2026-05-17T23:43:17Z","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":"0e477c1f8675b0ae6f2f7af84d06dad197a693d93bcb3a97a4f63fba3bf87a0c","cross_cats_sorted":["gr-qc"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-08-03T07:32:18Z","title_canon_sha256":"a307a2bda23aa210854440159a08fdcdbbcb97dedbc7a5dfb4e4bef51cba3e95"},"schema_version":"1.0","source":{"id":"1808.01103","kind":"arxiv","version":2}},"canonical_sha256":"a008150ceca87b3819f33650d9cb4defe67b88333437e3f7ab5f6c164ac793c3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a008150ceca87b3819f33650d9cb4defe67b88333437e3f7ab5f6c164ac793c3","first_computed_at":"2026-05-17T23:43:17.750584Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:43:17.750584Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"T0uSdR4Ko8CvJ8oUpTdZEwcOVKvvPagE6ay7W3I0zWprJ9lRtPulP/3/0AEs1nOAeSm61Oq4UKXsmgXPap7GCQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:43:17.751062Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.01103","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a3af308f4336ef6880bca05f6913ac95246d5f131376502fc2e474192e82cb7e","sha256:18e54049c5798d4ae02fd3897fa36c1b3c019ce62a6296ae25b85d9e98462244"],"state_sha256":"5ba6862553b00071051feb75b7daa944bbe872c8e4392fa793a2f43a1822805a"}
