Here we show that the binding energy of electron-hole pairs excited through this gap is larger than the gap itself in MoS2, a paradigmatic material that we investigate from first principles by many-body perturbation theory (MBPT). This paradoxical result hints at the instability of the T' phase against the spontaneous generation of excitons, and indeed we find that it gives rise ","authors_text":"Daniele Varsano, Elisa Molinari, Massimo Rontani, Maurizia Palummo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2019-06-19T08:40:22Z","title":"A monolayer transition metal dichalcogenide as a topological excitonic insulator"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1906.07971","kind":"arxiv","version":1},"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":"sha256:0e9dd2d41345c89677f4fadce326b19c6dc076823b9bfe4658b7cebf9e677a5c","target":"record","created_at":"2026-07-05T00:45:06Z","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":"82650ae648425787cca7b56407852db3b8a99f6910514eafb04ed6e8526b32c9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2019-06-19T08:40:22Z","title_canon_sha256":"093b4a85cd4e0536abf3bd3047c617d6357e4f65eae607dee74c76fcbb9777bc"},"schema_version":"1.0","source":{"id":"1906.07971","kind":"arxiv","version":1}},"canonical_sha256":"bc94565ed9d45e699cf2f92fe9450fe0ecb4bce516ba051b2c11a6f3c49b9e08","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bc94565ed9d45e699cf2f92fe9450fe0ecb4bce516ba051b2c11a6f3c49b9e08","first_computed_at":"2026-07-05T00:45:06.409022Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:45:06.409022Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5p0+IKIQnKUN+vGJDCVtB/eYWsPJlk3t135RQyUVSiqFCyLWKRxw4veR7fhY+nWEywgrA0d1q7AbO7ojzTb1DQ==","signature_status":"signed_v1","signed_at":"2026-07-05T00:45:06.409439Z","signed_message":"canonical_sha256_bytes"},"source_id":"1906.07971","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0e9dd2d41345c89677f4fadce326b19c6dc076823b9bfe4658b7cebf9e677a5c","sha256:13363ee630055ec017021340bef3d8a66ed20ce4bf7fda38d6dbfea2eb3c4ef2"],"state_sha256":"9e8cc76c4cd689f563663beee9a0ccbf904c0989a23d55b60357674c36bad5f3"}
