Numerical data of the renormalization group flow of fermionic self-energy close to quantum critical point in 2 dimensional metal

This data follows from the integrating the functional renormalization group (FRG) flow of the fermionic self-energy on the logarithim frequency grid in a non-self-consistent calculation.Two variants of the FRG flow were used: with bosonic regulator (nGenH) and without bosonic regulator (nFerm).The specific flow equations and integration methods are described in "Quantum criticality and non-Fermi liquids: the Wilsonian renormalization group perspective", arXiv:2505.10140v2 .The csv files (library_nFerm.csv and library_nGenH.csv) contain a coefficients specification for given npz files.Each npz file contains:frequency grid marked as "omega",time flow "lf",self-energy data for all times and frequencies "data",calculated logarithmic derivative "logder".Data for g=2, were used to plot the Fig. 6, 7, 8 in the paper "Quantum criticality and non-Fermi liquids: the Wilsonian renormalization group perspective", arXiv:2505.10140v2
