Perturbative Quantum Gravity - Lecture 4 | John Donoghue

This mini-course will focus on treating General Relativity as a perturbative quantum field theory. We will cover the field-theoretic construction and quantization of the theory. Useful field theory techniques will be introduced. Of course, renormalization will be discussed in detail. There will be an introduction to effective field theory, and we will see how the use of effective field theory techniques allows the calculation of quantum effects at ordinary scales. Finally, we discuss the limits of these techniques and try to point out some of the open directions.
