Many body physics provides the framework for understanding the collective behavior of interacting electrons in a material. This course provides an introduction to the field, familiarize you with the main techniques and concepts, aiming to give you first-hand experience in calculations and problem solving using many body methods.

Texts: The course will be built from the two excellent books:

1. Condensed Matter Field Theory by Alexander Atland and Ben Simons
A modern textbook on Field Theory with strong emphasis on modern tools like Functional field integral.
2. Many-Particle Physics by Gerald D. Mahan
A classical textbook dealing in detail with response functions such as Green's function and optical conductivity and more general Kubo formalism.

1. Many Body Physics by Piers Coleman
Great evolving monograph.
2. Methods of Quantum Field Theory in Statistical Physics by A.A. Abrikosov, L.P. Gorkov, I.E. Dzyaloshinski
Classic text from the sixties, known usually as AGD. Technically a bity more involved but contains many derivations which can not be found in any other book.
3. Basic Notion of Condensed Matter Physics by P.W. Anderson
Great inspiration from one of the "fathers" of strongly correlated field
4. Quantum Thoery of Many-Particle Systems by A.L. Fetter and J.D. Walecka
5. Field Theories of Condensed Matter Systems by Edwardo Fradkin
Interesting material on the fractional statistics and the fractional quantum Hall effect.
6. Introduction ot Superconductivity by Michael Tinkham
Great book on supeconductivity.
7. Interacting Electrons and Quantum Magnetism by Assa Auerbach
8. Quantum Field Theory in Condensed Matter Physics by Alexei M. Tsvelik
Very good for one dimensional systems. No excercises.
