Here, we show that this spin splitting can induce pair density wave states even in the absence of external magnetic fields. Focusing on BCS-type attractive interactions, we find the stabilization of symmetrically distinct pair density wave states depending on the chemical potential. These states include Fulde-Ferrell and Fulde-Ferrell* states, both of which break inversion symmetry. We investigate the supercurrent properties and discover non-reciprocal supercurrents f","authors_text":"Gibaik Sim, Johannes Knolle","cross_cats":["cond-mat.str-el"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2024-07-01T17:55:55Z","title":"Pair Density Waves and Supercurrent Diode Effect in Altermagnets"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2407.01513","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":"sha256:8b6a0f9f9bc7536e15ee0c4ef6ce42f415d120b0077f34ab63ea4142fe40c065","target":"record","created_at":"2026-07-05T11:36:20Z","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":"cee79919f4edb344db7df8daa4bac5ef01aa4930f1eb4edb755247842b2ca297","cross_cats_sorted":["cond-mat.str-el"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.supr-con","submitted_at":"2024-07-01T17:55:55Z","title_canon_sha256":"8a1f1bc685f1cb3d5d6b13ac32cf6c49931a38646177b16141c1fd6212da36b9"},"schema_version":"1.0","source":{"id":"2407.01513","kind":"arxiv","version":2}},"canonical_sha256":"19f13f3be34f494ab84fd29a5d6e57b1c8ce409cd7977666c32da9c61bf5b055","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"19f13f3be34f494ab84fd29a5d6e57b1c8ce409cd7977666c32da9c61bf5b055","first_computed_at":"2026-07-05T11:36:20.940506Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:36:20.940506Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+qqi7ZPOGxlDAs70cupliJ0brsS28qdmOj2R14X+Vll0zTL03QiG12yeepVrcbOmmEwZ4on2jg2yQLU8FdaQCA==","signature_status":"signed_v1","signed_at":"2026-07-05T11:36:20.941097Z","signed_message":"canonical_sha256_bytes"},"source_id":"2407.01513","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8b6a0f9f9bc7536e15ee0c4ef6ce42f415d120b0077f34ab63ea4142fe40c065","sha256:844ce409026a03fde90b96137e240ff666cc81ec26815861035b3c91345af630"],"state_sha256":"b73d0aaafe88e379576a3c87212d64a234eb2394c8ee5e810cb0653749d440b1"}
