A question readily accessible to atomic systems is related to the speed of propagation of matter-waves as a function of the lattice geometry. To address this issue, we have investigated theoretically the quantum transport of non-interacting and weakly-interacting ultracold fermionic atoms in several 2D optical lattice geometries. We find that the triangular lattice has a higher propagation velocity compared to the s","authors_text":"Chih-Chun Chien, Gia-Wei Chern, Massimiliano Di Ventra, Mekena Metcalf","cross_cats":["cond-mat.mes-hall","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2015-02-17T17:43:20Z","title":"Matter-wave propagation in optical lattices: geometrical and flat-band effects"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1502.04975","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":"sha256:1572464c5a043fe5a2293f1da5a8bf5f819b59cfc379b045e99462d113108741","target":"record","created_at":"2026-05-18T01:16:03Z","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":"5463c0c7c240d97c67e48ddd845d31c45eb6933dc6baddc52fd16f7a59072328","cross_cats_sorted":["cond-mat.mes-hall","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2015-02-17T17:43:20Z","title_canon_sha256":"cc982dcf41888196f5335d2bcd4ad57c402a007a9acffdba302cef396f701012"},"schema_version":"1.0","source":{"id":"1502.04975","kind":"arxiv","version":2}},"canonical_sha256":"e03096dbba814cc33e3c4f16fd43e332dd4027a5dd016cb047dce3ee50fed48f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e03096dbba814cc33e3c4f16fd43e332dd4027a5dd016cb047dce3ee50fed48f","first_computed_at":"2026-05-18T01:16:03.522640Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:16:03.522640Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kJeKHoAvLRYCdOGVyNG3ak6pZCNl22hPCEXbEN9nkJGVKA4CItj2co8tzjBKjNpFgq3XLgbYJ/DdVrYyrsTYCA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:16:03.523391Z","signed_message":"canonical_sha256_bytes"},"source_id":"1502.04975","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1572464c5a043fe5a2293f1da5a8bf5f819b59cfc379b045e99462d113108741","sha256:c60710ace695457b7c4dabfed7155ce452ddb98cc6e558c0d2e259538400c1a9"],"state_sha256":"eba2de5a82b0ceb8da3dd67aa389e3e23fc68f0d2a98295719731adf7bcfb92d"}
