Description
Surface operators are nonlocal probes of gauge theories capable of distinguishing phases that are not discernible by the classic Wilson-'t Hooft criterion. I will prove that the correlation function of a surface operator with a chiral primary operator in N=4 super Yang-Mills is a finite polynomial in the Yang-Mills coupling constant. Surprisingly, in spite of these observables receiving nontrivial quantum corrections, we find that these correlation functions are exactly captured in the 't Hooft limit by supergravity in asymptotically AdS5×S5! I will explain how to compute these correlation functions and other surface operator's observables using supersymmetric localization. I will also review how by perturbatively quantizing N=4 SYM around the surface operator singularity and identifying the Feynman diagrams one can reproduce the exact result obtained by localization. This talk is based on 2406.08541, with Changha Choi and Jaume Gomis.
