Fall 2020: PHYS 57000(U) “Quantum Gravity and Black Holes”
Tue-Thu 4:30-5:45 pm; Room PHYS 338
Prerequisites: Basic familiarity with general relativity at the level of Carroll’s book (a free version is here) and basics of quantum field theory at the level of Peskin-Schroeder’s book.
Course description: We will discuss black hole thermodynamics, path integrals in quantum gravity, holography and gauge/gravity dualities, and connections to quantum information theory and entanglement.
References: We will follow the structure of Tom Hartman’s lectures notes: (Lectures on Quantum Gravity and Black Holes)
Combined with these lecture notes:
Jared Kaplan’s lecture notes: (Why Quantum Gravity?) (Lectures on AdS/CFT from the bottom up)
Hong Liu’s lecture notes and recorded videos form the course Holographic duality
Gabor Sarosi’s notes on “AdS2 holography and the SYK model”
We will use the application Slack to post course announcements, reports, discuss ideas and share interesting papers we have come across. If you are planning to attend the class please send me an email and I will add you to the course channel on Slack.
The students should read the relevant section of the lecture notes before coming to class and submit two questions on slack. Every lecture will have homework problems that will be assigned in class and have to be submitted on Slack up to a week after the lecture.
There will be a term project and we will decide the groups in a few weeks. The videos of the lectures are available here.
Click on the lecture to download the lecture note. The videos of all lectures can be found in this YouTube Channel.
