Here, we report ballistic plasmonic Au nanoparticle (NP) swimmers with unprecedented speeds realized by not only optical pushing but also pulling forces from a single Gaussian laser beam. Both the optical pulling and high swimmer speeds are made possible by a unique NP-laser interaction. The Au NP excited by the laser at the surface plasmon resonance peak can generate a nanoscale bubble, which can encapsul","authors_text":"Dezhao Huang, Eungkyu Lee, Tengfei Luo","cross_cats":["physics.flu-dyn","physics.optics"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2019-08-16T14:26:39Z","title":"Ballistic Supercavitating Nano Swimmer Driven by Single Gaussian Beam Optical Pushing and Pulling Forces"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.05987","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":"sha256:5e2b98860255b9e44e0d833a892b043645a8f5fef4fa08661b92e479f8f18f32","target":"record","created_at":"2026-07-05T01:12:22Z","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":"780563c87116d11cac4bd79723657c6d01cb05740c95fffceff3ece32fc269fc","cross_cats_sorted":["physics.flu-dyn","physics.optics"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2019-08-16T14:26:39Z","title_canon_sha256":"c6f2f85a49297e73f8368bb7d3137bd7ec86891247a53215b3da9a0058b615b2"},"schema_version":"1.0","source":{"id":"1908.05987","kind":"arxiv","version":1}},"canonical_sha256":"451b22c74e8b11ce2df71423c3c5b17a914504849967e20b673898f5024feb34","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"451b22c74e8b11ce2df71423c3c5b17a914504849967e20b673898f5024feb34","first_computed_at":"2026-07-05T01:12:22.393713Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:12:22.393713Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zFIXUiUOUGVBMX6AbMMxZvK+OoHK4+vSqH+27p8/lDPuSJo6pvfIjimLjHTQ5noYWg4aKQ9dyC6rH1UyQPz3DA==","signature_status":"signed_v1","signed_at":"2026-07-05T01:12:22.394115Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.05987","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5e2b98860255b9e44e0d833a892b043645a8f5fef4fa08661b92e479f8f18f32","sha256:0494039a14fd036e14d890b7604ff03b187ce29324bca6e9529f71419f6be22f"],"state_sha256":"58bec7fc8205b7737746f1ac07c4931c0c0115a423503faaefac2572fb43cc05"}
