README

This folder contains data for the calculation of the coherence temperature. For each band filling, the data is presented in four columns: 
    Kondo coupling (J), hybrisation strength (r), electron chemical potential (μ), f-fermion chemical potential (λ)

File Naming Convention

The filenames follow the pattern:

fill_X.dat

Where:

    X represents the band filling for which the coherence temperature was calculated.

File Structure

Each .dat file contains four columns:

    Kondo Coupling (J): 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:

1.164	 0.009458	 3.893256	 3.893236
1.136	 0.008437	 3.893047	 3.893031
1.108	 0.007497	 3.892874	 3.892862
...

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.
The coherence temperature is then defined by Tcoh = r^2/D, for D the bandwidth of the bare model.

Usage

To analyze the coherence temperature as a function of the Kondo coupling for different band fillings, read the corresponding fill_X.dat file where X is the desired band filling.
