The work targets microgravity and space missions where such large uniform quantum gases could enable new many-body physics studies and precision sensors.","discovery_kind":"new_method","skeptic_critique":{"model":"deepseek-v4-flash","headline":"The largest-box ground state (dbox=2775.66 µm, p=99.1) rests on a stated painting frequency of 730.4 Hz that is not supported by any real-time GPE simulation; without that validation, the time-averaged approximation—and with it the thousandfold-volume claim—is unproven.","rationale":"The reader's weakest_assumption identifies the same gap. I agree. The paper has independent value: the dual-axis AOD setup, the measured residual scattering rate for 87Rb, and the demonstrated 2D painting patterns are concrete experimental achievements. The GPE methodology for the small box is credible, and the 2D reduction is benchmarked against 3D (Figure 7). However, the headline claim is about the largest scale. The largest box's ground state (p=99.1) is computed from a static time-average, and the only dynamic check presented is for the small box. The statement of ωpl,min=730.4 Hz for the large box is an unsupported assertion. Because the abstract claims a thousandfold volume increase and exponents up to 152, the missing large-box real-time validation is the most load-bearing unresolved issue. A revision should either provide the large-box real-time simulation or explicitly label the large-box density as contingent on painting-frequency validation. Thus the reader's CONDITIONAL verdict is appropriate and unchanged.","tokens_in":14506,"tokens_out":20219,"duration_ms":245779,"concrete_test":"Run the real-time GPE propagation for the dbox=2775.66 µm trap with 218 Gaussian spots (s=40 µm, Ppl=5 mW) at ωpl=2π×730.4 Hz, using the same effective-2D model and the kinetic-energy diagnostic as Figure 6, over at least several hundred cycles; if Ekin rises above the static ground-state value or the density develops periodic corrugation, the static-average ground state of Figure 5 is not realizable. For completeness, repeat at 2π×31.8 Hz and 2π×8 Hz to confirm the threshold.","verdict_should_be":"CONDITIONAL","load_bearing_attack":"Section 2.3.2 validates the time-averaged description only for the dbox=241.9 µm trap (Figure 6), where ωpl≥2π×31.8 Hz keeps kinetic energy flat. For the dbox=2775.66 µm trap, the text asserts \"the required minimal painting frequency also needs to be increased to ωpl,min = 2π×730.4 Hz\" with no supporting simulation figure or analytical criterion. This is load-bearing because the abstract's \"thousandfold larger trapping volumes\" and the p=99.1 density of Figure 5 depend on this static average being dynamically realized. The stated scaling is also non-obvious: the relevant atomic timescales (surface modes ~c/R) decrease with box size, so a 23-fold increase in required frequency is counterintuitive and needs verification. At 730.4 Hz with 218 spots, the dwell time per spot is 6.28 µs, only about 2.4 update periods of the 2.64 µs RF update and about 3 times the 2 µs AOD response time, so the painted intensity may deviate from the sum of static Gaussians used in the ground-state calculation. Without a real-time GPE run for the large box, the central claim remains contingent on an unverified approximation.","agreement_with_reader":"agree"},"referee_report":null,"author_rebuttal":null,"desk_editor":null,"rs_alignment":null,"lean_confirmation":null,"pith_extraction":null,"created_at":"2026-08-07T15:40:05.357056+00:00","model_set":{"reader":"deepseek-v4-flash"},"falsifier":null,"supporting_citations":[],"review_version":1}
