Using perturbative methods, we analyze an $s$-$d$ model on a geometrically frustrated lattice. Noncollinear local spin textures generate spin triplet pairing correlations and can favor spatially varying superconducting order due to anisotropic Josephson couplings between $d$ vectors, endowing a ``pliability'' to the pairing order that competes"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Coupling itinerant electrons to a noncollinear classical exchange field can induce anisotropic Josephson coupling between superconducting d vectors, analogous to the Dzyaloshinskii-Moriya and Γ-type interactions in magnetism.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The perturbative treatment of the s-d model on a geometrically frustrated lattice assumes that the local spins remain classical and noncollinear without significant quantum fluctuations or back-action from the superconducting electrons.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Noncollinear classical exchange fields on geometrically frustrated lattices induce anisotropic Josephson couplings between triplet d-vectors, enabling spatial pairing textures, anomalous vortices, and a chirality-proportional Josephson diode effect.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Coupling electrons to noncollinear spins on frustrated lattices induces anisotropic Josephson coupling between triplet d-vectors.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"7f95778abe3980a6f47d7a73081aaabb7d7c7fa3048162c89bb883e47b4c9008"},"source":{"id":"2506.15661","kind":"arxiv","version":3},"verdict":{"id":"1d618a5f-ba89-4410-bc89-01fbc97b598c","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-19T08:49:13.385393Z","strongest_claim":"Coupling itinerant electrons to a noncollinear classical exchange field can induce anisotropic Josephson coupling between superconducting d vectors, analogous to the Dzyaloshinskii-Moriya and Γ-type interactions in magnetism.","one_line_summary":"Noncollinear classical exchange fields on geometrically frustrated lattices induce anisotropic Josephson couplings between triplet d-vectors, enabling spatial pairing textures, anomalous vortices, and a chirality-proportional Josephson diode effect.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The perturbative treatment of the s-d model on a geometrically frustrated lattice assumes that the local spins remain classical and noncollinear without significant quantum fluctuations or back-action from the superconducting electrons.","pith_extraction_headline":"Coupling electrons to noncollinear spins on frustrated lattices induces anisotropic Josephson coupling between triplet d-vectors."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2506.15661/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
