The full quantum LTB model is constructed as a collection of non-interacting shells, each governed by an individual single-shell loop quantum dynamics. We show that the single-shell evolution is non-singular and that wave packets initially peaked on a collapsing trajectory undergo a bounce at Planckian energy densities and subsequently follow an expanding classical trajectory, resolving the classical central curvature sing","authors_text":"Farshid Soltani, Luca Cafaro","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2026-03-05T09:39:59Z","title":"A loop quantization of the marginally bound Lema\\^itre-Tolman-Bondi dust model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2603.04995","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":"sha256:99da14731b72e315c116f69b4defe1556c50cc970ae3de15775401ab5077e6f1","target":"record","created_at":"2026-08-07T00:51:29Z","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":"699b283776b00aa768754e269c91667ceddcb1b9e3656c42f9c575773473dd92","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2026-03-05T09:39:59Z","title_canon_sha256":"895028d7e1e5aa92bf0dc7e6bc68d42025b0e12bafe3e8ed63b393660943b689"},"schema_version":"1.0","source":{"id":"2603.04995","kind":"arxiv","version":2}},"canonical_sha256":"1f5f8064e3d2d5796dfc8d581a4fb817eab0aff0e8ecca07924144220f25a620","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1f5f8064e3d2d5796dfc8d581a4fb817eab0aff0e8ecca07924144220f25a620","first_computed_at":"2026-08-07T00:51:29.489918Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-07T00:51:29.489918Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bXmRwToFZpcc4OD7KqOQzQpW8D67HRCC/rAnBSCBIBzyO561K4TUIRjwP+3+Z3ndJrTxgwhHpIe9HwNHbg2QCA==","signature_status":"signed_v1","signed_at":"2026-08-07T00:51:29.491441Z","signed_message":"canonical_sha256_bytes"},"source_id":"2603.04995","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:99da14731b72e315c116f69b4defe1556c50cc970ae3de15775401ab5077e6f1","sha256:f5e0955a45877ecbb172d5301a564c8823d7f15ca6ebc4985c4cceb7bc0956ab"],"state_sha256":"ccddb9060940de4f776fc8536c9f34eed96a4437791f0a46fbac1a0aa39e3347"}
