WebMar 12, 2010 · The Similarity Renormalization Group (SRG) and V low k potentials evolve as a parameter is lowered. For the SRG, it is lambda, which is a measure of the spread of the momentum-space potential about the diagonal. For V low k, it is the momentum cutoff Lambda. There is a rough correspondence between the potentials at numerically similar … In theoretical physics, the term renormalization group (RG) refers to a formal apparatus that allows systematic investigation of the changes of a physical system as viewed at different scales. In particle physics, it reflects the changes in the underlying force laws (codified in a quantum field theory) as … See more The idea of scale transformations and scale invariance is old in physics: Scaling arguments were commonplace for the Pythagorean school, Euclid, and up to Galileo.
