gem.lattice.Lattice.compute_Gloc

Lattice.compute_Gloc(w_list, Fragments_list, eps=0.01)

Compute the local Green’s function at given frequencies from the quasiparticle problem using the self-energies from passed as a list of Fragment objects.

Parameters:

• w_list – ndarray. List or ndarray of frequencies at which to compute the local Green’s function.

• Fragments_list – List of Fragment objects that contain the self-energies.

• eps – float, optional. Small imaginary part that acts as a scattering rate or a broading (default: 1e-2).
