  • For 1D systems, the measured scaling exponent is consistent with the expected KZ defect scaling n ∝ t -1/μ a with z = 1 and ν = 1.

    “As in previous works 24,26 , the measured scaling exponent is consistent with the expected KZ defect scaling n ∝ t -1/µ a with z = 1 and ν = 1.”

    From Beyond-classical computation in quantum simulation (2025) · cites this paper as [24]

    The main text (p. 2) says the measured kink density agrees with coherent quantum theory in the fast-anneal regime and identifies its scaling exponent as −1/2, consistent with the claimed 1D Kibble–Zurek scaling. Our copy does not explicitly give the critical exponents z = 1 and ν = 1, and it reports anti-Kibble–Zurek behavior in a weak-coupling regime rather than agreement across all conditions. (LLM, conf=0.82)

  • All of the discussed Monte Carlo dynamics fail in one way or another to qualitatively reproduce quantum dynamics even in a pure one-dimensional system.

    “In particular, all of these dynamics fail in one way or another to qualitatively reproduce quantum dynamics even in a pure one-dimensional system 24 (see SM for Ref. 24, Figs.S4 and S5).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
