As a material system, we focus on diluted magnetic semiconductor quantum wells as they provide a strong spin-flip scattering for the carriers. Our study shows that overshoots can appear as a consequence of radiative decay even on the single-particle level in a theory without any memory. The magnitude of the overshoots in this case depends strongly on the temperature as well as the doping fraction of the material. If many-body effects beyond the single-particle level become important so that ","authors_text":"Florian Ungar, Moritz Cygorek, Vollrath Martin Axt","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2019-02-13T14:33:01Z","title":"Origins of overshoots in the exciton spin dynamics in semiconductors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1902.04921","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":"sha256:4851340d19bdd6486568bcfcef65ff8936e480f8f3e1510ceddfd77914081bb2","target":"record","created_at":"2026-05-17T23:47:48Z","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":"c723e49c062efa54f7d4523839a1ca6df4fe5913e93def376f564072df721782","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2019-02-13T14:33:01Z","title_canon_sha256":"02d96b12cfbcdf2bd7f4637a0e4d7bd4945aab5d684f3b8d727a1aa5e5ab9b22"},"schema_version":"1.0","source":{"id":"1902.04921","kind":"arxiv","version":2}},"canonical_sha256":"75e26f4c3aa6612c148c4553de90b4692abb4ff9623b5fcf541fd9a6049d0ccb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"75e26f4c3aa6612c148c4553de90b4692abb4ff9623b5fcf541fd9a6049d0ccb","first_computed_at":"2026-05-17T23:47:48.354282Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:47:48.354282Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kiW5b1pqKy6uTHlLg2d47kxt0R5BpOgRfh/I6OZWpmZs+dEcvQ473dxVRryuO0kukE0anuKmvpQlBfgAmP3jDQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:47:48.355046Z","signed_message":"canonical_sha256_bytes"},"source_id":"1902.04921","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4851340d19bdd6486568bcfcef65ff8936e480f8f3e1510ceddfd77914081bb2","sha256:ea64d8f8bde7adc4caf0524143118ea0d1c51aa595d2c0c64fd25aceca2115c8"],"state_sha256":"c8d40fb977f5953b7e7d40d0810b172e46a30a2a901658ca9b8efbd9e7cf651a"}
