FRGn Documentation
A small package that contains some of the subroutines and function which I frequently use in my code to numerically solve the exact Funcitonal Rrenormalisation Group equation in Graphene. The equations are motivated from the paper by Bauer et al [1]. Here apart from reproducing the result by them we also extend it to finite temperature and introduce the frequency dependence in the interraction term. See the example page.
