As the Fermi-Fermi pairing interaction is tuned, the background Fermi superfluid undergoes a topological phase transition. We show that such a transition is accompanied by a discontinuity in the second derivative of the polaron energy, regardless of the impurity-fermion interaction. We also identify a polaron to trimer crossover when the Fermi superfluid is in the strongly interacting, thus topologically trivial, regime. However, the trimer state is metastable against the molecular s","authors_text":"Fang Qin, Wei Yi, Xiaoling Cui","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2019-01-09T14:46:35Z","title":"Polaron in a $p+ip$ Fermi topological superfluid"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1901.02766","kind":"arxiv","version":3},"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:e21fc50fb0a3b6e751d936a9663652cf9f40bbca22e46fb9701cb79deee0cc42","target":"record","created_at":"2026-05-17T23:51:05Z","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":"31431e442b47afdcee04886cfbc225a6f3f8ff25256d53f10ae526087cf442ba","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2019-01-09T14:46:35Z","title_canon_sha256":"bad7002bfdd803dce70f6982e849ebe100fe5fcbb4ac2703e95d387dadc41228"},"schema_version":"1.0","source":{"id":"1901.02766","kind":"arxiv","version":3}},"canonical_sha256":"dc8bc6eb94ece791932b71394bb25c16d5f6c986795680c354063530445909a1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dc8bc6eb94ece791932b71394bb25c16d5f6c986795680c354063530445909a1","first_computed_at":"2026-05-17T23:51:05.073142Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:51:05.073142Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1chp5dK2HuBw5+orQ/2Phl87BltitG+S9qSrRaXJ29CeWWk/HtRIs51hEOCT222VF8ptJmz9VRXG0BJKWTe5Dw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:51:05.073632Z","signed_message":"canonical_sha256_bytes"},"source_id":"1901.02766","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e21fc50fb0a3b6e751d936a9663652cf9f40bbca22e46fb9701cb79deee0cc42","sha256:adde6b40f924f9a37d5aa1212f3f1d0a6a8064c7ac95cbe7f96696cac6d50311"],"state_sha256":"9d3ec70723439c78f1927dbf0afdea8f7042f99f65ddfdd90d9fae841539f1f2"}
