8.821 String Theory and Holographic Duality (Fall 2014, MIT OCW): Lecture 22

8.821 String Theory and Holographic Duality

8.821 String Theory and Holographic Duality (Fall 2014, MIT OCW). Instructor: Professor Hong Liu. This string theory course focuses on holographic duality (also known as gauge/gravity duality or AdS/CFT) as a novel method of approaching and connecting a range of diverse subjects, including quantum gravity/black holes, QCD at extreme conditions, exotic condensed matter systems, and quantum information.

Lecture 22 - Computation of the Wilson Loop

In this lecture, Prof. Liu first continues the discussion of the computation of the Wilson loop started in last lecture. He introduces the prescription for the computation and then uses it to calculate the Coulomb potential between a heavy quark and anti-quark in the N=4 SYM theory. In the second half, he discusses the generalization of the duality to a boundary system at a finite temperature.
