postprocessing.pade_sigma.main(external_path, n_w, w_min, w_max, n_iw, iteration=None, eta=0.0)[source] Main function that reads the Matsubara self-energy from h5, analytically continues it, writes the results back to the h5 archive and also returns the results.
Function parallelizes using MPI over impurities and blocks.
Parameters: - external_pathstring
Path to the h5 archive to read from and write to
- n_wint
number of real frequencies of the final self-energies returned
- w_minfloat
Lower end of range where Sigma is being continued.
- w_maxfloat
Upper end of range where Sigma is being continued.
- n_iwint
number of Matsubara frequencies to consider for the Pade approximant
- iterationint/string
Iteration to read from and write to. Default to last_iter
- etafloat
frequency offset within Pade
Returns: - sigma_wlist of triqs.gf.BlockGf
Sigma(omega) per inequivalent shell
