Thus, DFT primarily deals with length scales as those of a chemical bond, i.e. 10^-10 meter, and with time scales of the order of atomic vibrations, i.e. 10^-13 seconds. However, several interesting phenomena happen and/or become observable on different scales, namely meso- or macroscopic lengths and on time scales of seconds or even minutes. To bridge the gap between 10^-13 seconds and a second or between 10^-10 meter and 10 and more nano meters is one of the important challenges we are facing t","authors_text":"Alex Kley, Matthias Scheffler, Paolo Ruggerone","cross_cats":[],"headline":"","license":"","primary_cat":"cond-mat.mtrl-sci","submitted_at":"1998-02-02T10:36:57Z","title":"Bridging the length and time scales: from ab initio electronic structure calculations to macroscopic proportions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/9802012","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":"sha256:6c2444a714b175d5292809734cf81405ea970ef6b5106a847e7d4585f59b8bb4","target":"record","created_at":"2026-07-04T14:23:02Z","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":"0500bb4df1266dd55a63de5437d42bd82b25d374b277e6544134ca8b402fa794","cross_cats_sorted":[],"license":"","primary_cat":"cond-mat.mtrl-sci","submitted_at":"1998-02-02T10:36:57Z","title_canon_sha256":"739b1e939a37d5fb79338cc6a9cdb18408d4f52fb6b03d0ba9661cff527dba8c"},"schema_version":"1.0","source":{"id":"cond-mat/9802012","kind":"arxiv","version":2}},"canonical_sha256":"bd9590f19e5f988acfb277c170b9afd1675b33070393481150d2c09b717b145f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bd9590f19e5f988acfb277c170b9afd1675b33070393481150d2c09b717b145f","first_computed_at":"2026-07-04T14:23:02.457909Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T14:23:02.457909Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"aAkR1mXn3UAEIzqQPzkksgLtj+bfdxuA6MIRe+cLN1X5Sa/NFJD4Xbmri1GE70EpGBIWeI68EfOPJjhr9h4sBQ==","signature_status":"signed_v1","signed_at":"2026-07-04T14:23:02.458344Z","signed_message":"canonical_sha256_bytes"},"source_id":"cond-mat/9802012","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6c2444a714b175d5292809734cf81405ea970ef6b5106a847e7d4585f59b8bb4","sha256:7ff8504ab305664903cb2007999338b233d1d378510f1caeefab64444b7626fc"],"state_sha256":"d4f3c2a4eddf831936a1aae348881563aa4a34c658a62ba60b690b06b939350a"}
