You're missing the core drama of the story: Tristan is softly accusing OpenAI of having stolen their result from Codex chat logs. Tristan then claims OpenAI tried to threaten him to not publicly disclose this, and that they'd give him the Clay Prize ($1M) as the "closest humans to the problem" if he'd agree to disavow his co-author, @__alpoge__ , who is at Anthropic. This is HBO-level drama, but with math proofs.

SITUATION DETECTED: Mathematicians Tristan Buckmaster and Levent Alpöge have made major progress toward solving the Navier-Stokes existence and smoothness problem, one of the most important problems in mathematics, and say OpenAI may have solved it fully.

New preprint! We show that spin space groups can be used to analyze the optical response of matter (absorption, linear dichroism, spin Hall) even with strong spin-orbit coupling. Nice collab with Julen Ibañez-Azpiroz group at @CFMdonostia. Check it here: arxiv.org/abs/2608.16368

Optical Response Beyond Magnetic Symmetries

The optical response of magnetic materials is conventionally classified through magnetic space groups (MSGs), where spin and lattice are locked by the relativistic spin-orbit interaction. However,...

New preprint! We show that realistic excitonic many-body Hamiltonians obtained from first-principles GW-BSE calculations can exhibit quantum chaos governed by random-matrix universality. Nice collab with Rafa Molina @CSIC. Check it here: arxiv.org/abs/2607.03294

Many-body quantum chaos in excitonic spectra from first principles

Why paying peer reviewers works, according to a journal’s editor-in-chief

Nature - A biology journal that paid peer reviewers found that the approach cut the time to a first editorial decision by 85% and maintained high-quality reviews.
