In the semiclassical approximation, the ion is described by the Newton equation coupled to the Euler equation for the medium. After linearization, we obtain a simple closed formula for the effective mass of the impurity, depending on the interaction potential, the mean medium density, and sound velocity. Thus, once the interaction and the equation of state of the fluid is known, an estimate of the hydrodynamic effective mass can be quickl","authors_text":"Krzysztof Jachymski, Krzysztof My\\'sliwy, Piotr Wysocki","cross_cats":["physics.flu-dyn","quant-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2025-04-16T12:54:46Z","title":"No equivalence between hydrodynamic and dispersive mass of the charged polaron"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.12040","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":"sha256:742cc9207e73062419863040565455873439cd572d3281479be5def92563731d","target":"record","created_at":"2026-07-05T10:50:01Z","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":"7d6761d461dc0889f83f4d572c1fd7b2b05eb3671684ec9d9a3a4bdce2b8d3b9","cross_cats_sorted":["physics.flu-dyn","quant-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2025-04-16T12:54:46Z","title_canon_sha256":"6d238ca7dfc8425ec38c518696161a666131525606a367ecd8936f2646bd5496"},"schema_version":"1.0","source":{"id":"2504.12040","kind":"arxiv","version":1}},"canonical_sha256":"0bc7793e209ee17a15412f562c81d81e42d5eb71dba31cd8bc1992a62498ab5a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0bc7793e209ee17a15412f562c81d81e42d5eb71dba31cd8bc1992a62498ab5a","first_computed_at":"2026-07-05T10:50:01.756297Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:50:01.756297Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Tx8n34bHCf3r7mMFLru4o/YCPboiRceoeKkp0pWSs8aenzbfG6w1VIT3xkg4RN/XjZFktPzhE/C2swsJXOrQBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:50:01.756822Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.12040","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:742cc9207e73062419863040565455873439cd572d3281479be5def92563731d","sha256:6ab56f689f9101b9184243df5f964178917c84c9083d5b4ba27588ab22839622"],"state_sha256":"a4094585ff3aeca95d0a2dd9659ad3b42fe526324877b29751302c278fa73216"}
