Lecture 5: More on Rindler Space
In this lecture, after deriving the explicit Bogoliubov coefficients between the Unruh and Minkowski modes, we turned to a consideration of Rindler space in d+1 dimensions. The modes here are considerably more complicated. So, instead of trying to derive the Bogoliubov transformations using their global properties, we started a local derivation of the Unruh. Our strategy was to analyze the near-light-cone properties of two-point correlation functions in the Minkowski vacuum, and then use this to derive the two-point function of Rindler modes in the Minkowski vacuum. We encountered ultra-locality in the light-cone limit.
