numerrg's Introduction

###warning :: Work in progress

kondo-nrg

This is a Numerical Renormalization Group(NRG) code for the single site Anderson

impurity model. I have followed Rev. Mod. Phys. 80, 395(2008)

(https://doi.org/10.1103/RevModPhys.80.395) .

Dependence

It use LAPACKE (http://www.netlib.org/lapack/lapacke.html) for

matrix operations such as diagonalization, multiplication. It also use OPENMP for parallel computing.
