The Similarity Renormalization Group
Sergio Szpigel, Robert J. Perry
Quantum field theories require a cutoff to regulate divergences that result from local interactions, and yet physical results can not depend on the value of this cutoff. The renorm…

A New Renormalization Group for Hamiltonian Field Theory
Robert J. Perry, Sergio Szpigel
The Schrodinger equation with a two-dimensional delta-function potential is a simple example of an asymptotically free theory that undergoes dimensional transmutation. Renormalizat…
