Learning outcomes

At the end of the course the student will learn the basic elements of the Klein-Gordon and Dirac equations, and the path integral formulation of quantum mechanics. The student will be familiar with the use of the Klein-Gordon and Dirac equations for the description of relativistic particles of spin 0 and 1/2 and will be able to master the path integral for setting up the perturbative expansions of interacting theories.
