Scalar Field Theories
Part of the SpringerBriefs in Physics book series (SpringerBriefs in Physics)
In this chapter we put the RG concept to work on the simplest QFT based on a single real scalar field. This will illustrate how the conceptually simple idea of RG actually becomes challenging to implement in practice.
