Calculation of the FDM Spectrum

template<typename nrgcore_type>
class fdmSpectrum

Calculates the spectral function using the FDM (Full Density Matrix) approach.

This class computes the spectral weights and reduced density matrices for a given NRG core object.

Template Parameters:

nrgcore_type – The type of the NRG core object.

Public Functions

inline explicit fdmSpectrum(nrgcore_type *t_nrg_object)

Constructs the fdmSpectrum object.

Parameters:

t_nrg_object – Pointer to the NRG core object.

inline void setup(nrgcore_type *t_nrg_object)

Sets up the FDM spectrum calculation.

Parameters:

t_nrg_object – Pointer to the NRG core object.

inline void calcSpectrum(double energyScale)

Calculates the spectral function.

Parameters:

energyScale – The energy scale for rescaling.

template<typename filetype>
inline void saveFinalData(filetype *pfile)

Saves the final spectral data to a file.

Template Parameters:

filetype – The type of the file object.

Parameters:

pfile – Pointer to the file object.
