WebOct 1, 2024 · The renormalization group, which had been associated with a cautiously optimistic attitude towards the consistency of QFT question, was likely damned by association in the eyes of many. When Bjorken and Drell dedicated the final subsection of their 1965 QFT textbook to the renormalization group they no doubt further solidified its … 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.

WebRenormalization originated in quantum field theory as a method of removing UV divergences in perturbation expansions. The subsequent development in the 1960s of the renormalization group introduced the novel concept of running couplings, which depend on the energy scale at which they are measured, and led to such groundbreaking … WebMar 12, 2010 · The Similarity Renormalization Group (SRG) and V low k potentials evolve as a parameter is lowered.
