With the appropriate design of the additional wells PT-symmetric currents can be induced to and from the inner wells, which support stable solutions. We show that interaction in the mean-field limit does not destroy this property. As a first method we use a simplified variational ansatz leading to a discrete nonlinear Schr\\\"odinger equation. A more accurate and more general variational ansatz is then us","authors_text":"G\\\"unter Wunner, Holger Cartarius, J\\\"org Main, Manuel Kreibich","cross_cats":["cond-mat.quant-gas","nlin.CD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-08-01T12:52:11Z","title":"Realizing PT-symmetric non-Hermiticity with ultra-cold atoms and Hermitian multi-well potentials"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1408.0158","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:a006c4d8d6a68c5f564d75ce8d58f399d4deec8b5a43a56a1d67b080daaaebc1","target":"record","created_at":"2026-05-18T02:34:44Z","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":"6dfff011c03ecb0b90e4cbfb5e5bb4e4e380c8ee1112bd4966d35ecf49e90973","cross_cats_sorted":["cond-mat.quant-gas","nlin.CD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-08-01T12:52:11Z","title_canon_sha256":"7eb0ae819664ded953696b4e1aa5b0b818c7b42ab3689ebbfa91a0cfd090b82f"},"schema_version":"1.0","source":{"id":"1408.0158","kind":"arxiv","version":1}},"canonical_sha256":"8f2292ac5c0ee0b1aab1a3f9d7edd7ec4668f7b4080ba7b1046a73382491ab0b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8f2292ac5c0ee0b1aab1a3f9d7edd7ec4668f7b4080ba7b1046a73382491ab0b","first_computed_at":"2026-05-18T02:34:44.765032Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:34:44.765032Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"nIBU5MsaSe4BbLcnNy82CvNlGdMVoNM/vYNZVIXbLp9+oZhWlr1Yq3KyXO7as5XeJMi6AO4aWxD6PBtg9W4wBA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:34:44.765437Z","signed_message":"canonical_sha256_bytes"},"source_id":"1408.0158","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a006c4d8d6a68c5f564d75ce8d58f399d4deec8b5a43a56a1d67b080daaaebc1","sha256:4a1470b55e70863d9f4875fddf0500df61a5a6a2ae51b1d403bcd959c6d5d9bb"],"state_sha256":"decc7801660ccf0b8ef7436dad6ae5cc7d7c92402416544284a10620d0a71ce0"}
