While this situation has received considerable interest in recent years, the regime of strong coupling remained inaccessible to most approaches due to an instability in Bogoliubov theory arising near the resonance. We present a nonlocal extension of Gross-Pitaevskii theory that is free of such divergences and does not require the use of the Born approximation in any of the interaction potentials. We find a new dynamical transition regime between attractive and repulsive polarons, where an interacti","authors_text":"Manfred Salmhofer, Moritz Drescher, Tilman Enss","cross_cats":["cond-mat.str-el","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2020-03-04T10:30:05Z","title":"Theory of a resonantly interacting impurity in a Bose-Einstein condensate"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2003.01982","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":"sha256:7bbc96d7f934ecbf0fb06fbaa7f37d383c0f548a9b34f53b25c8d239a3deac19","target":"record","created_at":"2026-07-05T02:10:59Z","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":"0e7127a58dfa24aeba682344fff824b6290d994c062817746462b2adc25fb387","cross_cats_sorted":["cond-mat.str-el","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2020-03-04T10:30:05Z","title_canon_sha256":"90241018338064be443fe70ad5a6583ce50032a12ce86be0ea77c26850b751c1"},"schema_version":"1.0","source":{"id":"2003.01982","kind":"arxiv","version":2}},"canonical_sha256":"882d1d82b492581ee745e33a34ff63adb1ccfc1c36497b15815fb2411124d7d8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"882d1d82b492581ee745e33a34ff63adb1ccfc1c36497b15815fb2411124d7d8","first_computed_at":"2026-07-05T02:10:59.557513Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:10:59.557513Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kH+oy2Z/LVs/r/qBquVFEpWmUv/WotZMTao+ujvisT6uUaOdPGEfB7On8bGo+AyzTuiv0pYfmlB0hsYwLwPdCw==","signature_status":"signed_v1","signed_at":"2026-07-05T02:10:59.558069Z","signed_message":"canonical_sha256_bytes"},"source_id":"2003.01982","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7bbc96d7f934ecbf0fb06fbaa7f37d383c0f548a9b34f53b25c8d239a3deac19","sha256:336e4de9117300e0ad0e5d020c25c1868c7f0b81bcacec1378f2ec427c5c7b51"],"state_sha256":"8108c48bc82a666927c83fd3c48f825a9aca3fc0c1083cb12cc27595f6419eda"}
