Carving out OPE space and precise O(2) model critical exponents
Overview
Paper Summary
This paper develops new numerical bootstrap methods, including a "cutting surface" algorithm for scanning OPE coefficients, and applies them to the 3D O(2) model. The results improve the precision of scaling dimension calculations, further supporting Monte Carlo simulations over experimental findings and providing refined estimates for several OPE coefficients.
Explain Like I'm Five
Scientists found a new computer method to get super precise numbers about how materials change, like when water freezes. They learned that their computer's numbers were even better than what they measured in real experiments!

Rating Explanation
The paper presents valuable advancements in numerical bootstrap techniques, particularly the cutting surface algorithm for OPE scans. While the application to the 3D O(2) model refines existing results and doesn't resolve the experimental discrepancy definitively, the methodological contributions are significant. The limitations regarding non-rigorous aspects and computational cost prevent a perfect score, but the overall quality justifies a rating of 4.
