1. Renormalization group: 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 ... (Physics) [100%] 2023-08-02 [Renormalization group] [Quantum field theory]...
2. Renormalization group analysis: The theoretical physicist aims to elaborate theories at the microscopic scale, from which observed phenomena can be explained. Renormalization group analysis allows one to determine effective theories at each length scale, from microscopic to macroscopic, by averaging over "degrees of ... (Mathematics) [81%] 2023-09-01
3. Renormalization group for non-relativistic fermions: The renormalization group (RG) is a method for trading a given problem for an equivalent one that gives the same answers to a limited subset of questions. Often one begins with a theory that is good for all energies and ... [63%] 2021-12-24 [Statistical Mechanics] [Condensed matter]...
4. Functional renormalization group: In theoretical physics, functional renormalization group (FRG) is an implementation of the renormalization group (RG) concept which is used in quantum and statistical field theory, especially when dealing with strongly interacting systems. The method combines functional methods of quantum field ... (Implementation of the renormalization group) [81%] 2026-08-11 [Statistical mechanics] [Renormalization group]...
5. Numerical 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. The numerical renormalization group is an inherently non-perturbative procedure, which was originally used ... (Physics) [81%] 2026-08-11 [Renormalization group]
