We find that excitation continuum originating from magnons is quantized, when the staggered field induced by the weak inter-chain interaction is taken into account. The excitation energies of the quantized excitation spectra are well explained by negative zeros of the Airy functions, when the easy-axis anisotropy is strong and the ground state is located deep","authors_text":"Sei-ichiro Suga, Takafumi Suzuki","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2018-08-19T23:22:47Z","title":"Quantized excitation spectra by magnon confinement in quasi-one-dimensional S=1 spin systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.06270","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:b65f32eda5696ddfccef9180c908104e0225c73eaacec327b7692cd0bab25d20","target":"record","created_at":"2026-05-17T23:59:57Z","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":"65d36c7dd28f5d750c9c42415cddcfa548140d43987144b10ecc1dcb6ba7462e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2018-08-19T23:22:47Z","title_canon_sha256":"1f1e2bc897e2353870fe9fa0d407a5a6b69795e457ea272e2c6e5f9c9b4f774d"},"schema_version":"1.0","source":{"id":"1808.06270","kind":"arxiv","version":2}},"canonical_sha256":"79aec42b139591efb4f75497ba6ade804a4d1a91f46a2f7779aafad8b80dd898","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"79aec42b139591efb4f75497ba6ade804a4d1a91f46a2f7779aafad8b80dd898","first_computed_at":"2026-05-17T23:59:57.721271Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:59:57.721271Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gHYZpyLxE/42Pc4OCD3m+znJVP8PuxrVJx+J2kCIaf5nZlHYzimrVqzVzDhLo6bRSxWnTE7Xgon2DyB956p8AQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:59:57.721778Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.06270","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b65f32eda5696ddfccef9180c908104e0225c73eaacec327b7692cd0bab25d20","sha256:ea9a155b80f86727d4e90740fa2277420619f501ec2cc702ca18b704f07cf3c4"],"state_sha256":"83863c7d93d685ba2d587f31f852259846bf7cded7665b00cd3144775d35675c"}
