This page is for posting Lecture Notes, Problems Sets, Errata, Open Questions, and a Bibliography.
Note: During this lecture I mistakenly attributed the path integral derivation of Rindler wedge thermality. The correct reference is Unruh and Weiss (not Wald). This mistake has been corrected in the lecture notes. Also, the actual lecture ended around 1.6, the rest will be covered next time.
Lecture 2, Problem Set #2
Note: The recording of the lecture muddled the algebra of the Casini-Huerta proof of the c-theorem a bit, although the main ideas were all correct. It should be patched up in the notes, although you may prefer to get it directly from their paper (see bibliography).
Lecture 3, Problem Set #3.
Note: the proof of LM had some wrong signs, but I've fixed it in the scanned lecture notes. (But I made no effort to get the numerical coefficients right.) The notes also include a couple of pages of bonus material on the laws of black hole thermodynamics, not covered in class.
Lecture 6, followed by Discussion thereafter.
Note: My original lecture notes leave off at 5.2, but the last 5 pages of notes refer to a talk I gave on the quantum focussing conjecture. This goes into more detail than I discussed it during the Discussion, but it may provide some helpful context. I had no written notes for the "information puzzle" discussion, so please consult the video of the Discussion for that.
