Critical SK autocorrelation processes and dynamics across the temperature transition

OpenAI groups related papers into a “family”. OpenAI’s catalogue describes this one:

For zero-field Gaussian SK heat-bath dynamics with rate-one updates per spin, proves worst-start cutoff on the \(\log n\) scale for fixed \(0\le\beta\lt 1\), mixing time \(n^{2/3+o(1)}\) at β = 1, and stretched-exponential mixing from a Gibbs-sampled fixed starting configuration for β > 1, in probability over disorder. At criticality, rescaled stationary and quench autocorrelation processes have universal random limits for Gaussian and Rademacher disorder; the quench limit relaxes to the stationary limit. (OpenAI’s Lean note)

Lean is a language for mathematical statements and proofs that a computer can verify. The assessments below ask whether those statements express the result OpenAI describes here.

The paper states

Theorem 1.1 (Critical quench universality)

In Universality of critical quench autocorrelations in the Sherrington–Kirkpatrick model, 5 October 2026

Possible match to OpenAI’s description, selected from the papers’ main statements because it shares the most wording. No review confirming the selection is recorded.

Twelve other possible matches are listed below the card, among them Theorem 1.1 in A spectral gap throughout the high-temperature Sherrington–Kirkpatrick phase and Corollary 2 (Two-sided typical-start bounds) in A typical-start upper bound for low-temperature SK Glauber dynamics.

There is a measurable family (h_s^g)_{s>0}, with h_s^g\in L^2(\Pi_g), such that for almost every g the following properties hold.

  1. 1.

    For every s>0, h_s^g\ge0 and \Pi_g[h_s^g]=1. For s,t>0,

    h_{s+t}^g=S_t^g h_s^g.

    Moreover,

    h_s^g\Pi_g\ \weakto\ \delta_0 \quad\text{in the product topology on }\R^\N \quad(s\downarrow0), \qquad \|h_s^g-1\|_{L^1(\Pi_g)}\longrightarrow0 \quad(s\to\infty).
  2. 2.

    The series

    B_g(s,t)=\sum_{a\ge1} \int h_s^g(x)\,x_a\,(S_t^g x_a)(x)\,\dd\Pi_g(x)

    converges locally uniformly on (0,\infty)^2 and defines a continuous function.

  3. 3.

    For both choices of D,

    \Law_D(A_{n,J},B_{n,J}) \ \weakto\ \Law_g(A_g,B_g)

    in C_{\mathrm{loc}}((0,\infty)) \times C_{\mathrm{loc}}((0,\infty)^2). The two coupling laws have the same g, the same family h^g, and the same coefficient c_*.

  4. 4.

    For every 0<a<b<\infty,

    \sup_{a\le t\le b}|B_g(s,t)-A_g(t)| \longrightarrow0 \quad\text{in probability over }g \quad(s\to\infty).

The positive-time density limits of the Gaussian dynamics with initial law \nu_n select this family, as made precise in Theorem 6.1. The normalization is exactly (1.2)–(1.3).

Universality of critical quench autocorrelations in the Sherrington–Kirkpatrick model

5 October 2026, current edition.

Read it herePDF

We prove joint functional convergence of the stationary and quench autocorrelations of zero-field Sherrington–Kirkpatrick heat-bath dynamics at inverse temperature β = 1, with the same random limit for Gaussian and Rademacher couplings. Each site has a rate-one clock, mean spin autocorrelations are multiplied by n1/3, and waiting times and lags are measured in units n2/3. The quench starts from independent fair spins, and convergence is uniform on compact sets of positive waiting times and lags. The quench limit is selected by these initial states and relaxes to the stationary limiting autocorrelation as the waiting time tends to infinity.

Functional universality of critical SK autocorrelations

5 October 2026, current edition.

Read it herePDF

We prove that the stationary spin autocorrelation of the zero-field Sherrington–Kirkpatrick model at inverse temperature β = 1 has a common functional scaling limit for Gaussian and Rademacher couplings. With rate-one heat-bath clocks at every site, time is scaled by n2/3 and the mean spin autocorrelation is multiplied by n1/3. The functions converge in law uniformly on compact positive-time intervals. Their limiting law is not a point mass: it retains sample-to-sample randomness, and its functions decay to zero at large times.

A spectral gap throughout the high-temperature Sherrington–Kirkpatrick phase

24 September 2026, current edition.

Read it herePDF

For every fixed inverse temperature \(0\lt \beta\lt 1\), we prove that the unscaled spectral gap of single-site heat-bath dynamics for the zero-field Gaussian Sherrington–Kirkpatrick model is bounded away from zero with probability tending to one over the disorder. Equivalently, the Gibbs law satisfies a dimension-free Poincaré inequality for all functions.

Cutoff throughout the high-temperature Sherrington–Kirkpatrick phase

24 September 2026, current edition.

Read it herePDF

We prove worst-case total-variation cutoff for the zero-field Gaussian Sherrington–Kirkpatrick heat-bath dynamics at every fixed inverse temperature \(0\leq\beta\lt 1\). With rate-one refresh at each spin, the cutoff location is \(\log n/(2\lambda(\beta))\) for a positive deterministic rate \(\lambda(\beta)\). The location for uniformly chosen single-site update attempts is n times as large. Convergence is in probability over the disorder.

Critical slowing down in the Sherrington–Kirkpatrick model

24 September 2026, current edition.

Read it herePDF

At the critical inverse temperature β = 1, we prove slow mixing for zero-field Gaussian Sherrington–Kirkpatrick heat-bath dynamics from typical equilibrium configurations held fixed as initial states. For every deterministic sequence \(t_n=o(n^{2/3})\) in rate-one-per-site time, the Gibbs mass of initial states whose time-tn total-variation distance from equilibrium exceeds 1/4 tends to one in probability over the disorder. The same statement holds for every deterministic integer sequence \(k_n=o(n^{5/3})\) of uniform-site update attempts.

Stretched-exponential barriers for typical SK initial states

24 September 2026, current edition.

Read it herePDF

At every fixed inverse temperature β > 1, we prove a stretched-exponential obstruction to mixing for the zero-field Sherrington–Kirkpatrick model from typical equilibrium configurations held fixed as initial states. The Gibbs mass of states whose total-variation distance from equilibrium at time \(\exp(n^{1/10000})\) exceeds 1/4 tends to one in probability over the disorder. This holds for rate-one-per-site heat-bath dynamics and after the same stated number of discrete update attempts.

A typical-start upper bound for low-temperature SK Glauber dynamics

24 September 2026, current edition.

Read it herePDF

For every fixed inverse temperature β > 1, we prove subexponential mixing for rate-one-per-site heat-bath dynamics in the zero-field Gaussian Sherrington–Kirkpatrick model from a typical equilibrium configuration. If one Gibbs-sampled configuration is held fixed as the initial state, its total-variation distance from equilibrium is at most 1/4 by time \(\exp(n^{1-1/40000000})\), with joint probability tending to one over the disorder and the sampled state.

Critical mixing in the Sherrington–Kirkpatrick model

25 September 2026, current edition.

Read it herePDF

At the critical inverse temperature β = 1, we determine the worst-start total-variation mixing exponent for single-site heat-bath dynamics in the zero-field Gaussian Sherrington–Kirkpatrick model. The mixing time is \(n^{2/3+o(1)}\) when every site has rate one, or \(n^{5/3+o(1)}\) attempted uniform-site updates, in probability over the disorder.

SKBarriers

The paper states

Theorem B.1 (Polynomial-time obstruction from fixed-depth crossings)

In Stretched-exponential barriers for typical SK initial states, 24 September 2026

For every fixed \beta>1 and every fixed a>0,

\begin{aligned}\PP_{J,\,x_0\sim\pi^J} \left\{d^J(x_0,n^a)>\frac14\right\}&\longrightarrow1, \\ \PP_{J,\,x_0\sim\pi^J} \left\{d_{\mathrm{disc}}^J(x_0,\lfloor n^a\rfloor) >\frac14\right\} &\longrightarrow1.\end{aligned}

Consequently both \PP\{T^J(x_0)>n^a\} and \PP\{T_{\mathrm{disc}}^J(x_0)>n^a\} tend to one under the same joint law. Each assertion is equivalently a statement that the Gibbs mass of the indicated initial states tends to one in probability over J.

Independent comparisons and proof-verification reports

Does the Lean express the advertised result?

Neither group finds that the Lean statements express or imply the whole advertised result. They describe what the statements express in different terms.

MathVet and Carlos Toledo’s cert-machine independently assessed whether this family’s Lean statements express the whole result OpenAI describes in its catalogue. These are assessments of the family as a whole, not of each paper theorem separately.

MathVet finds that the Lean statements express part of the advertised result (their term: “partial”).

Their note: Stated: stretched-exponential barrier for β > 1 (SK.main : Tendsto continuousBadMass atTop (𝓝 1) ∧ Tendsto discreteBadMass atTop (𝓝 1) at time exp(n^(1/10000)), expected bad Gibbs mass over disorder); high-temperature spectral gap sk_main (0<β<1: Poincaré constant C and gap ≥ 1/(Cn)) as a supporting result; ratio cutoff ratio_cutoff only for 0 ≤ β < 1/2. Critical case is one-sided: critical_mixing_bounds gives n^(2/3-ε) ≤ continuousMixingTime ≤ exp(εn) (discrete n^(5/3-ε) ≤... ≤ exp(εn)), so the headline ‘mixing time n^{2/3+o(1)} at β=1’ has no n^{2/3+ε} upper bound in Lean. Not stated: cutoff for 1/2 <= β < 1 and its log n location, and the critical autocorrelation-process limits (Gaussian/Rademacher, quench relaxing to stationary).

Definitions the group asks readers to compare with the paper: Custom ‘mixing time’: continuousMixingTime W := sInf {t | 0 ≤ t ∧ ∀ x, continuousDistance W t x ≤ 1/4} (matrix exponential kernel NormedSpace.exp (t • generator W)), discreteMixingTime W := sInf {k : ℕ | ∀ x, discreteDistance W k x ≤ 1/4}, SKRatio.mixingTime g ε := sInf {k | discreteDistance g k ≤ ε}: standard worst-start total-variation mixing (sets are nonempty so sInf is a true min), but hand-written; SKBarriers uses its own heatBath kernel and a Poissonized continuousKernel (series in k).

“partial”, in their words: Only a special case is stated, or a co-equal headline claim has no challenge statement.

Their method: An independent, model-assisted, pre-referee reading of each family’s challenge statements against its headline claim under a published rubric (PROTOCOL.md), with its own Comparator runs per challenge.

cert-machine finds that the Lean statements express a narrower statement than the advertised result (their term: “NARROWER — UNLINKED”).

The gap they name: Not stated: the critical autocorrelation universality (clause 4, the titular result); the n^{2/3+o(1)} upper bound at β = 1; the stretched-exponential upper bound for β > 1; cutoff for 1/2 ≤ β < 1, its log n location and continuous time (this last part is declared). Stated: the high-temperature spectral gap (supporting), discrete ratio cutoff for β < 1/2, critical lower bounds with an e^{εn} upper bound, the β > 1 barrier, and critical covariance/linear-test scaling.

“NARROWER — UNLINKED”, in their words: The challenge statements state less than the headline; the missing part comes from a paper the Lean note does not link.

Their method: Every Comparator challenge re-run on Linux with nanoda switched on, decided by a preregistered rule.

OpenAI’s own note on what its Lean covers

For every fixed inverse temperature $0<\beta<1$, the formalization proves a dimension-independent Poincaré inequality for the zero-field Gaussian Sherrington–Kirkpatrick model with probability tending to one over the disorder. Equivalently, the unscaled single-site heat-bath spectral gap stays bounded away from zero. For dynamics that choose one site uniformly at each discrete step, the spectral gap is at least $1/(Cn)$ with probability tending to one, for a constant $C$ depending on $\beta$.

The formalized supporting result proves ratio cutoff for discrete single-site heat-bath dynamics in the zero-field Gaussian Sherrington–Kirkpatrick model for $0\le\beta<1/2$. For every $0<\varepsilon<1/2$ and $\eta>0$, the probability over the disorder that $t_{\mathrm{mix}}(\varepsilon)/t_{\mathrm{mix}}(1-\varepsilon)>1+\eta$ tends to zero as $n\to\infty$. The denominator is positive for all sufficiently large sizes. The paper’s full range $\beta<1$, explicit cutoff location, and continuous-time conclusion are outside this selected statement. At criticality in the zero-field Sherrington–Kirkpatrick model, the formalization proves that for every fixed $\varepsilon>0$, the continuous-time mixing time lies between $n^{2/3-\varepsilon}$ and $e^{\varepsilon n}$, and the discrete-time mixing count lies between $n^{5/3-\varepsilon}$ and $e^{\varepsilon n}$, with probability tending to one over the Gaussian disorder. The disorder has independent off-diagonal entries of variance $1/n$. Continuous updates have rate one per site; discrete time counts uniformly chosen single-site update attempts. Mixing is worst-start total variation at threshold $1/4$, with holding allowed. For deterministic times $t_n=o(n^{2/3})$ or update counts $k_n=o(n^{5/3})$, the Gibbs mass of realized starting states still farther than $1/4$ from equilibrium tends to one in probability. For every deterministic positive sequence $M_n\to\infty$, the covariance operator norm and the linear Rayleigh supremum, using the unscaled heat-bath Dirichlet form, both lie between $n^{2/3}/M_n$ and $M_n n^{2/3}$ with probability tending to one. The covariance result does not give an upper bound for the full inverse spectral gap. The formalization proves a stretched-exponential mixing obstruction for the zero-field Sherrington–Kirkpatrick model at every fixed inverse temperature $\beta>1$. At time $\exp(n^{1/10000})$, the expected Gibbs mass of initial configurations whose total-variation distance from equilibrium exceeds $1/4$ tends to one. Since this mass lies in $[0,1]$, it also tends to one in probability over the disorder. The result covers both rate-one-per-site continuous-time heat-bath dynamics and the same stated number of discrete update attempts.

Other proofs and exact calculations

These reports examine claims in the papers using exact calculations for finite claims, independently of the release’s Lean proofs. Read each report for the exact claim it covers.

    Their verdict
    “CERTIFIED” Exact code written independently from the paper confirms that the published object has the claimed property.
    What it covers
    “a finite component: Lemma rcut:lem:scalar-data and Table rcut:tab:scalar-intervals of the appendix route (the independent beta < 1/2 proof) - the 205 quadrature terms, every finite enclosure, the whole error budget and every interval bound recomputed by the appendix’s directed integer recipe; the trapezoid lemma, strip holomorphy and beta-monotonicity are read, not run, and the cutoff headline (all beta < 1) is proved elsewhere in the paper by a different argument”
