The obtained wave-function of the photon vortecies is the eigen-state of the z-component of the total angular momentum (zTAM). In m-th harmonic radiations, individual photons are the eigen-state of zTAM of m. This is consistent with previous studies. Using the presently obtained wave-functions we calculate the decay widths and the energy spectra under extremely strong magnetic fields of 10^12 - 10^13 G, which are observed in astrophy","authors_text":"Myung-Ki Cheoun, Takehito Hayakawa, Tomoyuki Maruyama, Toshitaka Kajino","cross_cats":["nucl-th","physics.optics","quant-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.HE","submitted_at":"2019-08-30T06:14:43Z","title":"Photon vortex generation in quantum level by high-order harmonic synchrotron radiations from spiral moving electrons in magnetic fields"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.11545","kind":"arxiv","version":3},"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":"sha256:7d5629659e98735c1a588f3a64b8cde65f877f66f3dda3ce61285d303edbb7e8","target":"record","created_at":"2026-07-05T03:39:52Z","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":"82ec4c0e60b0d6ef4ee2c114a430936e4f51c579b4b3c14d9b66dded6cb42761","cross_cats_sorted":["nucl-th","physics.optics","quant-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.HE","submitted_at":"2019-08-30T06:14:43Z","title_canon_sha256":"2c561a3efc910827c76ab55a99c15d3ee195b02f4ad1e2c04776775fe38bef2c"},"schema_version":"1.0","source":{"id":"1908.11545","kind":"arxiv","version":3}},"canonical_sha256":"2979acf2af33a1081f165db2fb4bd915e32efdb0bda1f38aceabec81291e008a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2979acf2af33a1081f165db2fb4bd915e32efdb0bda1f38aceabec81291e008a","first_computed_at":"2026-07-05T03:39:52.764159Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:39:52.764159Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+qLpmCusZlNgzaWyUC5pauSqtPx9h6M+vq4LMybnTSWS86G7uGpQFa7Vqj/BCgCRITVW6gfBExLDc8Ax0vYmBA==","signature_status":"signed_v1","signed_at":"2026-07-05T03:39:52.764502Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.11545","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7d5629659e98735c1a588f3a64b8cde65f877f66f3dda3ce61285d303edbb7e8","sha256:f5721a963d3e14c282f49e71bf2cf837e10bf7549360b7a8f7fed22ff006f9a8"],"state_sha256":"a1ef8c4451729d08324313a227949eb1a268cbdf14139044d12413c75f2aebdc"}
