Quantum Theory of Matter:

The aim of this course is to introduce the methods of quantum field theory applied to the many body problems in the Physics of Matter. The first part focuses on the perturbative methods and the response function theory applied to the electron gas with the use of the Green functions and the Feynman diagrams. In the second part it will be considered the quantum phenomena at low temperatures, superfluidity and superconductivity.
