These equations describe the time evolution of the nonequilibrium Green function for interacting many-body systems in the presence of time-dependent external fields. The external fields are treated nonperturbatively whereas the many-body interactions are incorporated perturbatively using Phi-derivable self-energy approximations that guarantee the satisfaction of the macroscopic conservation laws of the system. These approximations are discussed in detail for the time-dependent Hartree","authors_text":"Adrian Stan, Nils Erik Dahlen, Robert van Leeuwen","cross_cats":["cond-mat.other","cond-mat.str-el"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2009-06-09T11:58:30Z","title":"Time-propagation of the Kadanoff-Baym equations for inhomogeneous systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0906.1704","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:e51ee29210aa13037e906293e29b48d7dd7be130d1a9170c9841981ca6f54f29","target":"record","created_at":"2026-05-18T02:13:21Z","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":"762f7ae2d6040823cb0a0c0d102504cc3f30efe5f4a54b81876c0d615a988a1f","cross_cats_sorted":["cond-mat.other","cond-mat.str-el"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2009-06-09T11:58:30Z","title_canon_sha256":"a2467bdce3ec930f4c1594c88de196602e826c4523c6bfb9b55bb348c9c0017e"},"schema_version":"1.0","source":{"id":"0906.1704","kind":"arxiv","version":1}},"canonical_sha256":"c8b5cf795ac6133fcb0bb51a7e07662d1f324ddd0cbe24f4dd9756abe88002fc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c8b5cf795ac6133fcb0bb51a7e07662d1f324ddd0cbe24f4dd9756abe88002fc","first_computed_at":"2026-05-18T02:13:21.274662Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:13:21.274662Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"EdXO8kD0fx35+Z0aYHneAgLanrs0RwdlgnEqHipivnT4dSbaRjnlZJA4rOs1vAHFWFyNmOk7YGtZED500ubRBA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:13:21.275091Z","signed_message":"canonical_sha256_bytes"},"source_id":"0906.1704","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e51ee29210aa13037e906293e29b48d7dd7be130d1a9170c9841981ca6f54f29","sha256:fd63a9c6b6b4419b54e90105b925e0e9ffe11d7fe40eab8ba897b35ab164576d"],"state_sha256":"d341ffa1daed4b99a3ec9ae84e6412949e3bb67645bdd4dc0bc64982a786d6c3"}
