The heat flow generated in response to a voltage bias presents rectification as a function of the gate potential applied to the quantum dot. Remarkably, in the thermally driven case the heat shows a strong diode effect with large asymmetry ratios that can be externally tuned with magnetic fields or spin-polarized tunneling. Our results thus demonstrate the importance of hybrid systems as promising candidates for thermal applications.","authors_text":"David Sanchez, Sun-Yong Hwang","cross_cats":["cond-mat.supr-con"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2018-02-06T16:04:08Z","title":"Nonlinear heat transport in ferromagnetic-quantum dot-superconducting systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.02024","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":"sha256:3623473610222c963097d877a79275338f450de71ff08a588063208dabbeb94f","target":"record","created_at":"2026-05-18T00:17:53Z","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":"b758902d4ae9b26f718d6d431838ec0c3d0b1762d7c08f67adda75da67f6b95b","cross_cats_sorted":["cond-mat.supr-con"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2018-02-06T16:04:08Z","title_canon_sha256":"b008df1b4990a1eb510f975b970793519e894dbb95d74a7b51ea2290263a8d9f"},"schema_version":"1.0","source":{"id":"1802.02024","kind":"arxiv","version":1}},"canonical_sha256":"7a22baa845aa08556eee4e176b42b46cd3b4973fa5b39cd6f5e2da53889a4cfc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7a22baa845aa08556eee4e176b42b46cd3b4973fa5b39cd6f5e2da53889a4cfc","first_computed_at":"2026-05-18T00:17:53.474051Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:17:53.474051Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rBfa4AZRsPNWfZ5m49AVrA08Xc35DTJ3y3xS8NZGN4aaDFVZZFMWPIwXlf39FCAN8OXVX1+biU6emLDkwx/2Cg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:17:53.474573Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.02024","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3623473610222c963097d877a79275338f450de71ff08a588063208dabbeb94f","sha256:1c4a5e54513fe5e1f6558794f6b71343c0b5d263382d1ee5e385a5053b33e616"],"state_sha256":"5ca263224d67529dbfe827d14e287942ed6b1b6d5b51e2dbd9b0eb4b3f536cab"}
