Using Bootstraps to Refine the O(2) Model, Because 80s Discrepancies are Totally Bogus!
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.
Possible Conflicts of Interest
None identified
Identified Weaknesses
Incremental Advancements
While the paper presents improvements in numerical bootstrap methods and applies them to the 3D O(2) model, the core findings primarily refine existing results and don't offer fundamentally new insights.
Non-Rigorous Aspects of OPE Scan
The reliance on heuristics for certain steps of the OPE coefficient scan introduces non-rigorous elements into the analysis.
Limited Exploration of Central Charges and OPE Coefficients
The computational cost of the analysis limited the exploration of central charges and certain OPE coefficients to non-rigorous estimates.
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.
