The implementation of high harmonic generation to obtain a higher photon energy also allows us to investigate the wide Brillouin zone on a time scale below 100 fs. In this article, we review our recent studies using high-harmonic-generation-laser-based time- and angle-resolved photoemission spectroscopy to study a variety of quantum materials. We reveal many unprecedented phenomena in each system and highlight some representative resu","authors_text":"Kozo Okazaki, Shik Shin, Takeshi Suzuki","cross_cats":["cond-mat.mtrl-sci","cond-mat.supr-con"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2021-07-20T01:37:59Z","title":"HHG-laser-based time- and angle-resolved photoemission spectroscopy of quantum materials"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2107.09221","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:b64f4902745456500ac4f2c329779b9b88bea31bae14692e32eb97c6be2fca29","target":"record","created_at":"2026-07-05T04:35:08Z","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":"4933f1b0cb71a91bd817490442e9a235e4a4433b0cdca951c5538a868352b0a0","cross_cats_sorted":["cond-mat.mtrl-sci","cond-mat.supr-con"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2021-07-20T01:37:59Z","title_canon_sha256":"8b0b41e10faa5d049a5aa2a51d3186e0d190c9d710e139818c987aec9dd31f2d"},"schema_version":"1.0","source":{"id":"2107.09221","kind":"arxiv","version":1}},"canonical_sha256":"347c42b889d018a3901cc0dd23490b3129abf7888eeb4e01c7c5e65169777eb3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"347c42b889d018a3901cc0dd23490b3129abf7888eeb4e01c7c5e65169777eb3","first_computed_at":"2026-07-05T04:35:08.962844Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:35:08.962844Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RyO2vzXV1pBR/3b3PGBWjezKo+MLAuXryJoqsuazq1ORq5/g/R9tYTE5+PIBmmGO5XCIRYsQS5koJPMmYQqMDA==","signature_status":"signed_v1","signed_at":"2026-07-05T04:35:08.963281Z","signed_message":"canonical_sha256_bytes"},"source_id":"2107.09221","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b64f4902745456500ac4f2c329779b9b88bea31bae14692e32eb97c6be2fca29","sha256:77a1cb3af153e65c52b9d3ac2439c3b0b69fc99851205aa7f29aa9b07a83e2de"],"state_sha256":"0074e2bff5391c1c1e5778eefefd66d51ce5a1d53004740d250a899b5a0daf6b"}
