Numerical renormalization group
The Numerical Renormalization Group is a method devised by Kenneth Wilson et al. to solve many-body problems. It is a numerical non-perturbative procedure, which was used in 1975 to solve the Kondo model for low temperature. It was applied to the Anderson model by Krishnamurthy et al.[1] in 1980.
It is an iterative procedure, which is an example of a Renormalization group technique.
