The ground state and low-lying excitations are solved by both numerical and analytical methods. It is shown that the ground state is an isospin-ferromagnetic state and the excitations are composed of three elementary particles: holons, antiholons and isospinons. The isospinon is a triplet coupled to the ``ferr","authors_text":"Shi-Jian Gu, Ulrich Eckern (Augsburg Univ.), You-Quan Li (Zhejiang Univ/Augsburg Univ), Zu-Jian Ying (Zhejiang Univ.)","cross_cats":[],"headline":"","license":"","primary_cat":"cond-mat.str-el","submitted_at":"2001-07-27T16:10:51Z","title":"Two component interacting bosons: 1-d exact results"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/0107578","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:c9418f1a23ba2c47f8011f0f77de4e575ca7859fcff4a97f23a3e14ae5a5a93f","target":"record","created_at":"2026-05-18T01:40:06Z","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":"fc18a5b137e70c87530a6f02f57ce4d51d291800d517f92c30a23d8022e11727","cross_cats_sorted":[],"license":"","primary_cat":"cond-mat.str-el","submitted_at":"2001-07-27T16:10:51Z","title_canon_sha256":"7bb0d994af1ab98b49a75282df4b482fffde1329c6c65440f89f932699372183"},"schema_version":"1.0","source":{"id":"cond-mat/0107578","kind":"arxiv","version":1}},"canonical_sha256":"8d6f218e8fdd934ec75981f6974a4d7991c0c0d75c15668df5c1304183720157","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8d6f218e8fdd934ec75981f6974a4d7991c0c0d75c15668df5c1304183720157","first_computed_at":"2026-05-18T01:40:06.976536Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:40:06.976536Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Pn0sfJNHGXxL1229s7AiaxVAPrTTI/ENSkMjzqGuRLvLbvWodcOqYB49MRxJxAyi83hf5g0Yurad/nF/888mDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:40:06.977081Z","signed_message":"canonical_sha256_bytes"},"source_id":"cond-mat/0107578","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c9418f1a23ba2c47f8011f0f77de4e575ca7859fcff4a97f23a3e14ae5a5a93f","sha256:c32b955a11e6c8f677ee6bb73dcdf48af0ac11d2c6b5a6601304691f2d1f3c3c"],"state_sha256":"1edc73af04a035eaa3a0dd3dda23c8213372e5ecf65485bb48a430e17feee796"}
