We present an all-optical method for the deterministic spatial selection of single- and bilayer samples of cold dipolar atoms using spatially selective parametric heating within a beat-note superlattice. By utilizing a high-resolution microscope objective as a common retroreflector for both optical frequency components, the lattice planes are passively sta"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"We validate this approach by demonstrating the robust isolation of one or two atomic layers in precise coincidence with the focal plane of our objective.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"The parametric heating is assumed to be sufficiently layer-selective to remove atoms from undesired planes without significantly disturbing the target layers, and the passive stabilization via the microscope retroreflector is assumed to eliminate drifts over the relevant timescales.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"An all-optical beat-note lattice technique isolates single- and bilayer dipolar quantum gases at the microscope focal plane via selective parametric heating.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"All-optical parametric heating in a beat-note superlattice isolates single or bilayer dipolar atom samples at the microscope focal plane.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"244e71d54ae37aa1a93b1dfca6bfeab6678c534f88982b4ca031b7bf51682949"},"source":{"id":"2605.13482","kind":"arxiv","version":1},"verdict":{"id":"79d0eff9-cba1-4e25-87fa-44ecbd19837e","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-14T18:27:45.235771Z","strongest_claim":"We validate this approach by demonstrating the robust isolation of one or two atomic layers in precise coincidence with the focal plane of our objective.","one_line_summary":"An all-optical beat-note lattice technique isolates single- and bilayer dipolar quantum gases at the microscope focal plane via selective parametric heating.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"The parametric heating is assumed to be sufficiently layer-selective to remove atoms from undesired planes without significantly disturbing the target layers, and the passive stabilization via the microscope retroreflector is assumed to eliminate drifts over the relevant timescales.","pith_extraction_headline":"All-optical parametric heating in a beat-note superlattice isolates single or bilayer dipolar atom samples at the microscope focal plane."},"references":{"count":46,"sample":[{"doi":"","year":1971,"title":"V.
