A comparison with the results calculated from the typical Bogoliubov approximation indicates that the additional interaction terms contributed by the excited modes play a significant role to explain the dynamics of the stimulating process. The td-GHFB model has not only painted a clear picture of the density wave propagation, but also partly explained the generation of the second order harm","authors_text":"Bo Yan, Tao Chen","cross_cats":["cond-mat.quant-gas"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"physics.atom-ph","submitted_at":"2018-09-10T06:05:17Z","title":"Characterization of the stimulated excitation in a driven Bose-Einstein condensate"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1809.03146","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":"sha256:4d28e1f748cca86fd344c28f0329030868694058e9e296cf4a5022da701b156d","target":"record","created_at":"2026-05-17T23:58:03Z","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":"47f30e95cb256a9d13d14d385bb31d714932d8e6034541e2fdf2df198c4a9db8","cross_cats_sorted":["cond-mat.quant-gas"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"physics.atom-ph","submitted_at":"2018-09-10T06:05:17Z","title_canon_sha256":"03bdbf4175fab52de470dcda45bf6fe5d9050b6db62198d2d82ccdf970fe8240"},"schema_version":"1.0","source":{"id":"1809.03146","kind":"arxiv","version":2}},"canonical_sha256":"d6d8b43e0f21a1ad8db101e6b082604510766b149a88e3e82dd3ec627a8f4e69","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d6d8b43e0f21a1ad8db101e6b082604510766b149a88e3e82dd3ec627a8f4e69","first_computed_at":"2026-05-17T23:58:03.917887Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:58:03.917887Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7T2MFtF+4aN7UjRew7L1vjOmmjUoCet6LYyvFVbCPKq06yk2pYa5blujpb5ocHg6FHXrT7mtzXevL1OsH28/CA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:58:03.918285Z","signed_message":"canonical_sha256_bytes"},"source_id":"1809.03146","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4d28e1f748cca86fd344c28f0329030868694058e9e296cf4a5022da701b156d","sha256:f2b40fac0b6ee57fa9213213ed0b0a898f7a3af42f7f602c2cd84b3718aada34"],"state_sha256":"92fb87e02a73996cbc79348ec0ecb00b05f76f4ecdf7c0821c1feb365b483fb6"}
