High Energy Theory Group Seminar: Wilson loops and minimal surfaces in Euclidean AdS_3

Abstract:

In this talk I will discuss the problem of Wilson loops at strong coupling using the AdS/CFT correspondence. Using the AdS/CFT dictionary the Wilson loops are described by minimal surfaces ending on a contour on the AdS boundary. I will describe several approaches to the problem in Euclidean AdS_3 (or equivalently the hyperbolic space H_3), based on the integrability of the problem. I will show how one of these approaches can be used to solve the problem perturbatively around the circular solution to very high orders compared to the wavy approximation, and how these results can be used to study nontrivial properties of these Wilson loops.
