Lattice.fit_mu_quasiparticle(n_target, Fragments_list, T=0.01, mu_old=0.0, ntol=0.0001)

Procedure to fit the chemical potential from the quasiparticle problem.

Parameters:

• n_target – float. Target filling.

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

• T – float, optional. Electronic temperature (default: 0.0).

• mu_old – float, optional. Previous chemical potential, to help the search (default: 0.0).

• ntol – float, optional. Tolerance on the filling for convergence (default: 1e-4).
