In this work, we study the optical forces acting on a resonant dielectric nanoparticle placed near a metal interface, where scattering occurs into both free-space and surface plasmon-polariton (SPP) channels. We show that the interference of electric and magnetic dipole moments leads to highly directional scattering in these channels, and the direction and magnitude of the scattering-induced force a"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"We show that in a cross-beam configuration, where the radiation-pressure contribution is suppressed, the optical force can be changed for almost 2π in a wide range of particle sizes that provides a route toward optical sorting of resonant nanoparticles.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The assumption that interference between electric and magnetic dipole moments produces highly directional scattering into both free-space and SPP channels whose angular directivity directly determines the direction and magnitude of the scattering-induced force, and that the cross-beam geometry fully suppresses radiation-pressure contributions without introducing other uncontrolled effects.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Interference of electric and magnetic dipoles in Mie particles near metal surfaces produces directional scattering that tunes scattering-induced optical forces over almost 2π in cross-beam configurations, enabling resonant nanoparticle sorting.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Interference of electric and magnetic dipoles directs scattering forces on Mie particles near metal interfaces.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"fd57448b606dd2e4af4120673d2a8fa87fdf7f05ccceb0c545fa150c70310696"},"source":{"id":"2604.19428","kind":"arxiv","version":2},"verdict":{"id":"5aaa032b-2a78-4d42-bdc7-3d4a56c43903","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-10T01:46:12.724842Z","strongest_claim":"We show that in a cross-beam configuration, where the radiation-pressure contribution is suppressed, the optical force can be changed for almost 2π in a wide range of particle sizes that provides a route toward optical sorting of resonant nanoparticles.","one_line_summary":"Interference of electric and magnetic dipoles in Mie particles near metal surfaces produces directional scattering that tunes scattering-induced optical forces over almost 2π in cross-beam configurations, enabling resonant nanoparticle sorting.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The assumption that interference between electric and magnetic dipole moments produces highly directional scattering into both free-space and SPP channels whose angular directivity directly determines the direction and magnitude of the scattering-induced force, and that the cross-beam geometry fully suppresses radiation-pressure contributions without introducing other uncontrolled effects.","pith_extraction_headline":"Interference of electric and magnetic dipoles directs scattering forces on Mie particles near metal interfaces."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2604.19428/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
