README

This folder contains numerical data for the all the mean field parameters at each temperature Τ. Each file corresponds to a specific band filling, and the data is presented in four columns:
Temperture (T), hybrisation strength (r), electron chemical potential (μ), f fermion chemical potential (λ)
The data are used to obtain the Kondo temperature by an appropriate fitting.

File Naming Convention

The filenames follow the pattern:

n=X_J=Y.dat

Where:

    X represents the band filling for which the data was generated. We follow the conventions:
        0 <= filling <= 2
        The fillings corresponding to the flat band are 0 <= filling <= 2/3
        The chemical potential at the flat band is such that μ(Τ=0) = -2.0t
    Y represents the Kondo coupling at which the calculation was performed

File Structure

Each .dat file contains four columns:

    Temperature (T): Measured in units of t (bare hopping parameter)
    Hybridisation strenght (r): Measured in units of t (bare hopping parameter)
    Electron chemical Potential (μ): Corresponding value of the electron chemical potential at the given temperature, also in units of t.
    Electron chemical Potential (λ): Corresponding value of the f-fermion chemical potential at the given temperature, also in units of t.

Example data format:

0.043000	 0.052676	 -2.192899	 -0.003452
0.042000	 0.053578	 -2.193709	 -0.003607
0.041000	 0.054392	 -2.194529	 -0.003755
...

Usage

To obtain the Kondo temperature and generate a plot for the fitting, read the corresponding n=X_J=Y.dat file where X is the desired band filling and Y is the Kondo coupling.
