A ripplon has a dispersion relation $\\omega\\propto k^{3/2}$ due to the nonlocality of the effective Lagrangian, which is mediated by gapless superfluid phonons in the bulk. We point out the analogy to the longitudinal phonon in the two-dimensional Wigner crystal.","authors_text":"Haruki Watanabe, Hitoshi Murayama","cross_cats":["cond-mat.other","hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2014-03-13T18:50:54Z","title":"Nambu-Goldstone bosons with fractional-power dispersion relations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1403.3365","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":"sha256:7f21d5534e9c79dcec615d02d1f2122580ba6ab9ffd33b3c162738c2b7268668","target":"record","created_at":"2026-05-18T02:45:31Z","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":"504fb45819fa1ac37d63f147c6e166af5ea8491c935c652e0f66399fc4f2979f","cross_cats_sorted":["cond-mat.other","hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2014-03-13T18:50:54Z","title_canon_sha256":"f2c686fe7cb6c19bc2468da07d5f8b2fca54b2811a3896e58760b530fdcf0f41"},"schema_version":"1.0","source":{"id":"1403.3365","kind":"arxiv","version":2}},"canonical_sha256":"ba34bd88ad16a2e0bd5c03ebc87b6eae4a065489bc75fdbd8f1c9b1cad8d68b7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ba34bd88ad16a2e0bd5c03ebc87b6eae4a065489bc75fdbd8f1c9b1cad8d68b7","first_computed_at":"2026-05-18T02:45:31.544830Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:45:31.544830Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"avHYSScga0N6zmeSnpMnXajbFBf5hiChECF39HQXaoX4meyTw/1mt/23gL401DraUzjBqFgaCbYtKsqqnLfADg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:45:31.545417Z","signed_message":"canonical_sha256_bytes"},"source_id":"1403.3365","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7f21d5534e9c79dcec615d02d1f2122580ba6ab9ffd33b3c162738c2b7268668","sha256:c81dc093f0bbff1d7cf1853c5beb55caf35adc651a99f7f6de4fba5dfedf62bb"],"state_sha256":"ee6af154d7bc6377780c752633b9034712987a016e60b8a393a6d48b750c6488"}
