Description: his course is aimed at graduate students in all fields of theoretical physics. Pre-requisites are basic notions in ordinary quantum mechanics and general relativity. The course is organized in two lessons per week, for 4 weeks. Each lesson is scheduled to be 1h30′ long. Exercises will be suggested at each lesson. Notes for the course will be ready during the course or shortly after it.
Introduction to general relativity. Spin of the gravitational waves, gauge choices. Source overview and order of magnitudes. Interactions of gravitational waves with experimental detectors. Green functions and field boundary conditions.
Effective field theory applied to toy models. The two body problem in general relativity. The post-Newtonian approximation. Effective field theory derivation of the Einstein-Infeld-Hoffman potential.
The effective field theory point of view of non-relativistic General Relativity. The Feynman integral as a basic tool to compute observables in General Relativity. The multipole expansion.
Emission of gravitational waves. The quadrupole formula and its first order corrections. Tail and memory effects. Regularization of divergences and renormalization of physical quantities in field theory and its application to General Relativity.
