renormalization group
1Renormalization group — In theoretical physics, the renormalization group (RG) refers to a mathematical apparatus that allows systematic investigation of the changes of a physical system as viewed at different distance scales. In particle physics, it reflects the… …
2Renormalization group equation — may refer to:* beta function * Callan Symanzik equation * Exact renormalization group equation …
3Numerical renormalization group — The Numerical Renormalization Group (NRG) is a technique devised by Kenneth Wilson to solve certain many body problems where quantum impurity physics plays a key role. It is an inherently non perturbative procedure, which was originally used to… …
4Density matrix renormalization group — The density matrix renormalization group (DMRG) is a numerical variational technique devised to obtain the low energy physics of quantum many body systems with high accuracy. It was invented in 1992 by Steven R. White and it is nowadays the most… …

6Butcher group — In mathematics, the Butcher group, named after the New Zealand mathematician John C. Butcher by Hairer Wanner (1974), is an infinite dimensional group first introduced in numerical analysis to study solutions of non linear ordinary differential… …
7On shell renormalization scheme — In quantum field theory, and especially in quantum electrodynamics, the interacting theory leads to infinite quantities that have to be absorbed in a renormalization procedure, in order to be able to predict measurable quantities. The… …
8Wave function renormalization — In quantum field theory, wave function renormalization is a rescaling, or renormalization, of quantum fields to take into account the effects of interactions. For a noninteracting or free field, the field operator creates or annihilates a single… …
