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 04 - Physical Interpretation of Black Hole Temperature

In this lecture, Prof. Liu gives a physical interpretation of the black hole temperature, and similarly the temperature experienced by an accelerated observer in Minkowski spacetime, in terms of entanglement of the vacuum state of a quantum field theory in these spacetimes.
