In addition to the density-dependent interactions, this model also contains nonlinear coupling terms between the two components of the polariton. Using a mean-field calculation, we obtain the phase diagram which shows how these terms affect the transition between the Mott insulator and the superfluid phase. In addition, we employ both a perturbation approach and an exact diagonalization method to gain more insights into the phase diagram.","authors_text":"Guang-Can Guo, Han Pu, Xiang-Fa Zhou, Xingxiang Zhou, Yong-Chang Zhang, Zheng-Wei Zhou","cross_cats":["quant-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"cond-mat.str-el","submitted_at":"2015-05-08T14:29:18Z","title":"Two-component Bose-Hubbard model in an array of cavity polaritons"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1505.03835","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:a6012162531a1bca0a6ad16fc1b2d2622a2a3f05490e024d666a2f8f59035595","target":"record","created_at":"2026-05-18T01:55:00Z","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":"c090e68dc958a9fa512bcdd2ce81851732667455ea59d245199e8e11b7f3c930","cross_cats_sorted":["quant-ph"],"license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"cond-mat.str-el","submitted_at":"2015-05-08T14:29:18Z","title_canon_sha256":"e3bf331dcb3e1db55c1ee151b8e832e721e066eb6eeb27b3864a8f086035924b"},"schema_version":"1.0","source":{"id":"1505.03835","kind":"arxiv","version":1}},"canonical_sha256":"186c76f88cb8e8d7c5b9fca5dd0678d500b51b09db7bccf2e63bb648a03fd70d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"186c76f88cb8e8d7c5b9fca5dd0678d500b51b09db7bccf2e63bb648a03fd70d","first_computed_at":"2026-05-18T01:55:00.409787Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:55:00.409787Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BnkR8utvevCVJnL0UlivyRPLLqFcgFLa2GiL6hVV+b2ZfhIATzB7X/avidbMLuBTMPC1dX4WTSm25VTWuvknDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:55:00.410457Z","signed_message":"canonical_sha256_bytes"},"source_id":"1505.03835","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a6012162531a1bca0a6ad16fc1b2d2622a2a3f05490e024d666a2f8f59035595","sha256:c3d521f4a21bc05bcb98d6b974cba656271ff0225e9f4675a2ea7ce8fd55076e"],"state_sha256":"055b24c11f84a25e44dab34c7d6bab9db3757ab630c514500660e96cac496f35"}
