Functional Methods functions. For a self-contained introduction to the FRG it is therefore necessary to properly define the various generating functionals and develop some intuition for the meaning of the associated correlation functions, which we shall do in this chapter. Moreover, we shall use the invariance proper

Superfluid Fermions: Partial Bosonization in the Particle–Particle Channelves only small momentum transfers, such a procedure is not appropriate for other types of interactions. For example, the superconducting instability of a normal metal is triggered by particle–particle scattering processes with vanishing total momentum, so that in this case a Hubbard–Stratonovich dec
