README

This folder contains data for all the mean field parameters (r, μ, λ) at given band filling (n=0.03) and Kondo coupling (J=0.97), as a function of temperature.
These data are used in the calculation of the observables such as entropy and heat capacity as functions of temperature, and are split into three files (for ease) 
corresponding to very low temperatures (T < T_K), high temperatures (T > T_K) and some very high temperatures (T >> T_K)


File Naming Convention

The filenames follow the pattern:

mid_n=0.03_J=0.97.dat   : Low temperature data
above_n=0.03_J=0.97.dat : High temperature data
high_n=0.03_J=0.97.dat  : Very high temperature data

File Structure

Each .dat file contains four columns:

    Temperature (T): Measured in units of the bare hopping parameter t.
    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:

0.860000	 0.000000	 -4.852422	 0.000000
0.850000	 0.000000	 -4.816874	 0.000000
0.840000	 0.000000	 -4.781373	 0.000000
...

Calculation Method

The mean field parameters (r,μ,λ) have been obtained by numerically solving the mean field equations for the given band filling and Kondo coupling.

Usage

To analyze the observables as a function of Temperature for different band fillings and Kondo couplings, read the file.
