Using the density matrix renormalization group, we calculate how the locations of phase transitions change with increasing dipolar interaction strength for average density $\\rho = 1$. Furthermore, we show an emergence of pair-correlated phases for a large dipolar interaction strength and $\\rho \\geq 2$, including a supersolid phase with an incommensurate density wave ordering manifesting the ","authors_text":"Jakub Zakrzewski, Krzysztof Biedro\\'n, Mateusz {\\L}\\k{a}cki","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2018-02-22T15:39:04Z","title":"Extended Bose-Hubbard Model with dipolar and contact interactions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.08104","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":"sha256:90ffbcaa61dc36e74b414c57cf7846020ef9fafd511675707727c73f7ddfa027","target":"record","created_at":"2026-05-18T00:14:13Z","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":"5c69ce9cacefc57200a03d012c1409dd7b0b7b64ddf1ade7acf81809fd678c51","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2018-02-22T15:39:04Z","title_canon_sha256":"b2a17e2a5c46adac1383eb4a47cb0642ae3ed173dd79f266debfd761b00fdda5"},"schema_version":"1.0","source":{"id":"1802.08104","kind":"arxiv","version":2}},"canonical_sha256":"54914e43dc35684f6dd70651551b9dc4be65eb835e789bf4be3cacbf32dbc779","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"54914e43dc35684f6dd70651551b9dc4be65eb835e789bf4be3cacbf32dbc779","first_computed_at":"2026-05-18T00:14:13.989470Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:14:13.989470Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"T4pN/F0npdzp2uivObgBDAvkMYK4N/gOV8DKG0rQEaQqCg7UF6UYDSzOrtEn1LSHGT0vfW/Ttka7yC6EI67IBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:14:13.990469Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.08104","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:90ffbcaa61dc36e74b414c57cf7846020ef9fafd511675707727c73f7ddfa027","sha256:8d476f4fa60a82a7cb97b51ea82791dc5fe6ce50ef570ea443f8df1876bbc552"],"state_sha256":"88789c05e708976239fd2979d8c20b899d8bd6ed5fbe91105b32ca6f09c39747"}
