Università Roma Tre

The course offers an introduction to the methods of field theory
applied to the study of many-body systems of Physics
Matter. The course program includes the first part of the
study of perturbation methods and linear response theory
applied to the electron gas with the use of the Green's functions and
Feynman diagrams. In the second part it is developed it
theoretical study of quantum phenomena that characterize the matter
at low temperatures as superfluidity and superconductivity
