We show that the minimum energy state, the ground state, has a lattice structure, where the translation invariance of the continuum theory is reduced to a discrete translation symmetry. The scale of translation symmetry breaking (or induced lattice spacing) is proportional to the inverse of the momentum of the condensate particle.\n  The crystalline ground state is stable under excitations below a ","authors_text":"Subir Ghosh (Indian Statistical Institute)","cross_cats":["cond-mat.other","gr-qc","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-08-22T07:53:08Z","title":"Spontaneous Generation of a Crystalline Ground State in a Higher Derivative Theory"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1208.4438","kind":"arxiv","version":4},"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":"sha256:12e2d4a7315da0f3c858111f73a5acd06c55ec5f36673bc2048263ec437db0c6","target":"record","created_at":"2026-05-18T02:54:56Z","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":"1e343594ee7feed2dec49b2790ff2d34fd76962f18efcb19787bb51120740897","cross_cats_sorted":["cond-mat.other","gr-qc","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-08-22T07:53:08Z","title_canon_sha256":"ce8d2c6c54260b80d789f3a0a6fbace53ccfdaa090b49c7e349a4f1f8713b4db"},"schema_version":"1.0","source":{"id":"1208.4438","kind":"arxiv","version":4}},"canonical_sha256":"4262b5a1df3af89a646e79d40bd1f4fe3a7693d3d9fe8f401e334ba04c24b848","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4262b5a1df3af89a646e79d40bd1f4fe3a7693d3d9fe8f401e334ba04c24b848","first_computed_at":"2026-05-18T02:54:56.483520Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:54:56.483520Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7ypOS2pYFAZoa9OTt+4GoXunK83UTK56Hljx55Yg6xhZSDOq5C2379ztcV8PXqWj0R05nhNTJrtuUzPXykkOBw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:54:56.484032Z","signed_message":"canonical_sha256_bytes"},"source_id":"1208.4438","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:12e2d4a7315da0f3c858111f73a5acd06c55ec5f36673bc2048263ec437db0c6","sha256:c95ae0eda3a4b1945d34313a9e0bf57f3fcd2516121c36f0faf7dce8aff145fc"],"state_sha256":"e15f2c741c172bfb083e227d06ea202ab6643310a6702668e5c95a4c870dc89b"}
