Abstract
Starting from this chapter, we will solve many different problems that occur in practice in condensed matter physics. First, to warm up, we will choose one problem of a fermionic system and one of a bosonic system. We will examine the RPA theory of the Coulomb gas and the Bogoliubov theory of superfluidity using path integral methods.
