Physicists say AI agents chose and solved a PRL-worthy problem in two hours

Christopher Herzog, physics professor at King's College London, reports that he and Andy Stergiou had ChatGPT and Claude autonomously pick a problem, do the analysis and draft a paper suitable for Physical Review Letters. The two agents each proposed three ideas, ranked the six and agreed on one — a conjecture bounding the specific-heat-to-central-charge ratio of 3d CFTs by the free scalar. The first draft took a couple of hours; the humans then spent two weeks verifying everything and rewriting the prose. The resulting paper, "The Free Scalar as a Thermal Envelope for Three-Dimensional CFTs," conjectures cS/CT ≤ 16πζ(3) and tests it in free, large-N and holographic theories plus Monte Carlo data for 3d Ising and O(N) models.
