Comparing with the usual low energy few particle tunnelling process, we find that the soliton tunnelling leads to massive particle transport between two wells. The {population imbalance} between two wells is not evolving sinusoidally with the time as the Josephson plasma oscillation, but shows a higher density contrast square-wave pattern due to the reflections at the trapping potential boundaries. Such unusual behavior clearly demonstrates the topologically stable, localized na","authors_text":"Chenglong Jia, DeCheng Ma","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2019-03-01T03:16:59Z","title":"Square wave oscillation of soliton in double-well potential trapped BEC"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.00141","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":"sha256:0082fba9e35c7326d7a546ea4d4ee836409df53a29ca4c677b968b5982b50f31","target":"record","created_at":"2026-05-17T23:52:20Z","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":"cd5fc3e801dff4dac2bb50c396da8840f1efabc5b315b7c9188b6452c9b747e4","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2019-03-01T03:16:59Z","title_canon_sha256":"8c048b6aca8ac9e696534e7efd9eb70672fbdaa1fc9643864dfa5b95b7f9cd65"},"schema_version":"1.0","source":{"id":"1903.00141","kind":"arxiv","version":1}},"canonical_sha256":"f0eafc61e684567be7ba270b3309f093d0bb1584a5e00500f6c029fd80c7086c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f0eafc61e684567be7ba270b3309f093d0bb1584a5e00500f6c029fd80c7086c","first_computed_at":"2026-05-17T23:52:20.790279Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:52:20.790279Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9wOYWVhXdFz47Zo/WllgWNcHg/AfUIv6uRFpYmbGMv6l+Oro3MJwHoPVcyPJIi88sOtG2woA/7P250tQuC3JAg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:52:20.790926Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.00141","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0082fba9e35c7326d7a546ea4d4ee836409df53a29ca4c677b968b5982b50f31","sha256:3a4af5f94b75eec9261e9a1b52c96c6f4efc68e2c3698bee3db218b2a0cfd8b4"],"state_sha256":"2b72bfec111a06eecadee69c29ead0993d97c26325814b8affbdcf85f5741ddd"}
