Musings on Entanglement Entropy in String Theory - Lecture 3

Explore advanced concepts in string theory through this lecture on entanglement entropy by Raghu Mahajan from Princeton University. Delve into topics such as ADM mass, gauge transformations in string theory, and diffeomorphisms. Examine the work of Susskind and Uglum, and investigate the potential of string theory to address UV divergences in quantum field theories. Gain insights into black hole entropy from a string worldsheet perspective. Follow along as the lecture covers Maxwell cases, path integrals over non-zero modes, and a six-point function example. Participate in a Q&A session and conclude with a discussion on diffeomorphisms in this comprehensive exploration of entanglement entropy in string theory.
