8.821 String Theory and Holographic Duality (Fall 2014, MIT OCW): Lecture 03 - Causal Structure of a Black Hole and Black Hole Temperature

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 03 - Causal Structure of a Black Hole and Black Hole Temperature

In this lecture, Prof. Liu first discusses the causal structure of black hole geometry, and that of a closely related spacetime called Rindler spacetime. He shows that a black hole has a nonzero temperature to an observer at infinity. He also derives a closely related phenomenon: In Minkowski spacetime, an accelerated observer feels a temperature proportional to her acceleration.
