An exotic band structure that is effectively described by the spin-1 Maxwell equations is imaged. Three-fold degenerate points dubbed Maxwell points are observed in the Maxwell metal bands. Moreover, we engineer and observe the topological phase transition from the topological Maxwell metal to a trivial insulator, and report the first experiment to measure the Chern numbers that are higher than one.","authors_text":"Dan-Wei Zhang, Guangming Xue, Hai-Feng Yu, Hui Yan, Qiang Liu, Shi-Liang Zhu, Xinsheng Tan, Yang Yu, Yan-Qing Zhu","cross_cats":["cond-mat.mes-hall","cond-mat.supr-con"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2017-09-18T03:40:25Z","title":"Topological Maxwell Metal Bands in a Superconducting Qutrit"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.05765","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":"sha256:44e4085f4d3ef40b4c3b102459a0512135f8d791547cc17ecfbec4b06bdcc91f","target":"record","created_at":"2026-05-18T00:19:26Z","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":"aaabf7e2efde95087bad46c9c0c8bd46479468fa5fcaf57f9ba977ac4fcbb6c7","cross_cats_sorted":["cond-mat.mes-hall","cond-mat.supr-con"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2017-09-18T03:40:25Z","title_canon_sha256":"b94118e67b79817051d2bc501551eddbe24238e30daac2d90fac9033a36d5650"},"schema_version":"1.0","source":{"id":"1709.05765","kind":"arxiv","version":2}},"canonical_sha256":"7753a58d1b8a09644eaf4d0a5b0e6077d09f5886344be7c0485e50a758944f90","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7753a58d1b8a09644eaf4d0a5b0e6077d09f5886344be7c0485e50a758944f90","first_computed_at":"2026-05-18T00:19:26.803295Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:19:26.803295Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fBoSNqkJFLNoZMhwbVXRRBVRz7NzacqpONS+3sLp2yIuIoY/l2NN+cqfBqWyTQfOaKNC+tCbPaFXTijK1P3lCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:19:26.803877Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.05765","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:44e4085f4d3ef40b4c3b102459a0512135f8d791547cc17ecfbec4b06bdcc91f","sha256:10c306c76cf9425f5f7aa2c3899eb52ce3533283418579186900da869cfc3029"],"state_sha256":"6bfc5b14aaa4faca74fdd9cc3d5cc3c6d396a417ed5ee4ac0594e60ae5a4b5f0"}
