Abstract: In the gauge/string duality, Wilson loop operators are dual to open string minimal surfaces anchored on the loop at the boundary of AdS. In the simplest example, a circular Wilson loop corresponds to an open string worldsheet with AdS2 geometry. The scattering amplitudes of the worldsheet fluctuations are holographically dual to one-dimensional correlation functions in the defect CFT associated with the Wilson line. I will give an overview of recent progress on this system. The results have applications in various contexts, such as the conformal bootstrap, integrability, the g-theorem for defect RG flows, and chaotic behavior of out-of-time order correlators.
