Spectral gaps of high-temperature SK heat-bath dynamics

For the zero-field Gaussian Sherrington–Kirkpatrick model at each fixed 0<β<1, seek a dimension-independent Poincaré bound for all observables for rate-one-per-site heat-bath dynamics, with disorder probability tending to one. Equivalently, uniformly selected single-site updates should have gap at least 1/(Cβ n).

Why it matters and what counts as progress

Why it matters: It asks for control of the slowest heat-bath mode throughout the high-temperature phase, beyond covariance bounds for linear observables.

What counts as progress: Extend a dimension-independent all-observable Poincaré bound through the full fixed β<1 range; covariance estimates alone do not suffice.

How the problem developed

  1. 16 Jul 2020 · Partial result [1]

    Ronen Eldan, Frederic Koehler and Ofer Zeitouni Proved a dimension-free Poincaré inequality for Ising measures when the positive interaction matrix has operator norm below one; this yielded a smaller high-temperature range for SK dynamics.

  2. 24 Sept 2026 · Proof claim [2]

    OpenAI Reported a dimension-independent Poincaré inequality for zero-field Gaussian SK heat-bath dynamics at every fixed 0<β<1, with disorder probability tending to one.

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

OpenAI

For the zero-field Gaussian Sherrington–Kirkpatrick model at every fixed 0<β<1, rate-one-per-site heat-bath dynamics satisfy a dimension-independent Poincaré inequality for all observables with disorder probability tending to one. Uniformly chosen single-site updates have gap at least 1/(Cβ n).
