Repulsive interactions between nearest neighbors drive a quantum phase transition from a Dirac semimetal to a charge-density-wave state through a fermionic quantum critical point, where the coupling of Ising order parameter to the Dirac fermions at low energy drastically affects the quantum critical behavior. Encouraged by a recently discovery of absence of the fermion sign problem in this model, we study the fermionic quantum critical point using the continuous time quantum Monte Carlo method wit","authors_text":"Lei Wang, Matthias Troyer, Philippe Corboz","cross_cats":["hep-lat"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2014-06-30T20:00:29Z","title":"Fermionic Quantum Critical Point of Spinless Fermions on a Honeycomb Lattice"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1407.0029","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:e31b57c6d53bf016314e2225073d34b11818c5003547862b669eca1085fd7f16","target":"record","created_at":"2026-05-18T02:40:53Z","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":"46fd7b80d07f8a09194f213030fc491f94bf325a78a221abc6ee251d76476f31","cross_cats_sorted":["hep-lat"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2014-06-30T20:00:29Z","title_canon_sha256":"0b74f3e94386bed241bddd3c93572ca47323236b612cfb335b627515f7ce26c8"},"schema_version":"1.0","source":{"id":"1407.0029","kind":"arxiv","version":1}},"canonical_sha256":"efafa95bb2a4ae0927d7e3f223bf642577db32f88099ae1c5e22a53608638537","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"efafa95bb2a4ae0927d7e3f223bf642577db32f88099ae1c5e22a53608638537","first_computed_at":"2026-05-18T02:40:53.823267Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:40:53.823267Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TCBEB9HrZd7GJ9QgpxeYrtAtfnHKF0I35bGvV6hEEeyXZRCHNLdmCvdEbxUSgXiD7d+LrmQxXNehBoDbwWFbAw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:40:53.823769Z","signed_message":"canonical_sha256_bytes"},"source_id":"1407.0029","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e31b57c6d53bf016314e2225073d34b11818c5003547862b669eca1085fd7f16","sha256:f6b376aa6c45be9bf9201c4ebe200f0bbd70cfdbfab7586950e2487b0d8d2a12"],"state_sha256":"151384bdccbb486564be83896b49a17b22e409478990c24e1e926d8036673521"}
