Coarse-Graining as a Route to Microscopic Physics: The Renormalization Group in Quantum Field Theory.

The renormalization group (RG) has been characterized as merely a coarse-graining procedure that does not illuminate the microscopic content of quantum field theory (QFT) but merely gets us from that content, as given by axiomatic QFT, to macroscopic predictions. I argue that in the constructive fie...
