Here, exploiting the phase-temperature thermodynamic diagram of a thermally isolated system, we argue that a cooling effect can be achieved when the phase drop across the junction is brought from 0 to $\\pi$ in a iso-entropic process. We show that iso-entropic cooling can be enhanced with proper choice of geometrical and electrical parameters of the junction, i.e. by increasing the ratio between supercurre","authors_text":"Alessandro Braggio, Elia Strambini, Francesco Giazotto, Francesco Vischi, Matteo Carrega, Pauli Virtanen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2018-06-05T09:18:14Z","title":"Coherent Josephson thermodynamic cycles"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.01568","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":"sha256:2e6bc794ccd6ccb40ca758360a9dcfc65bbc520f030823b56459287c6dc781e3","target":"record","created_at":"2026-05-17T23:52:24Z","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":"7dbe7ccc0d5795a193a4a59d2d8e4be957836971d38c6d83f65d905d852cc00e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2018-06-05T09:18:14Z","title_canon_sha256":"3e6c1e42d3c3d6a6205431567656394bfaee069b7598ac88512987f990aa44f5"},"schema_version":"1.0","source":{"id":"1806.01568","kind":"arxiv","version":1}},"canonical_sha256":"61d13347719e130867fe5c8259b4743e29a8e0a761e7abf32df56ba8c4a51bfe","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"61d13347719e130867fe5c8259b4743e29a8e0a761e7abf32df56ba8c4a51bfe","first_computed_at":"2026-05-17T23:52:24.398279Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:52:24.398279Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9MIidg73JXSQF5MdaMdnJpCY2FjASJZxevBhEFvlZrwcIG/qjVzfMuVVtAf9qbpixx3NqfVzRG29EAJRe798Bg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:52:24.398746Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.01568","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2e6bc794ccd6ccb40ca758360a9dcfc65bbc520f030823b56459287c6dc781e3","sha256:f7e3ddb82ade355bca11a122cca648070d4654798fd2a8517f822ef3bb868509"],"state_sha256":"0a4dc77644ea94dbe8e65c09dc48f4f332df05be45f1138c95b5d731306dd396"}
