OpenAI reports fixed-energy GOE statistics for weakly disordered regular graphs

For every fixed degree d≥3, sufficiently weak fixed positive uniform diagonal disorder on a uniformly random simple d-regular graph yields the GOE bulk microscopic eigenvalue point process at each fixed energy separated from the clean spectral edges, after rescaling by the corresponding tree density of states.

What was already known

Earlier random-regular-graph results gave local laws, delocalization, energy-averaged bulk statistics, or clean-model fixed-energy universality; weak-disorder quantum ergodicity did not identify the full fixed-energy microscopic point process.

AI involvement AI-led

OpenAI credits itself as manuscript author and states that its internal frontier model produced the results in this release. Individual human input is not detailed enough to establish task-only autonomy.

OpenAI is named as author on the manuscript, and its release attributes the results to an internal frontier model. The individual human input is not detailed enough to establish autonomy.

Importance Notable

Extends fixed-energy GOE bulk universality to positive weak Anderson disorder at every fixed regular degree.

Limitations

Disorder strength depends on degree and distance from clean spectral edges and stays fixed as graph size grows; the energy must remain in a compact interior band. No completed proof check was documented in the available sources.

Technical verification Reported

Reported is the default when evidence for a higher level is insufficient. The OpenAI-authored manuscript reports and argues the result, but the reviewed sources do not document a completed check of the full assessed claim.

Human understanding Few

Few is the default when evidence for a higher level is insufficient. No named person is documented as explaining the central argument for this assessed contribution.
