Function Documentation

vector<matrix<complex<double>>> QCM::self_energy(const complex<double> w, const vector<vector3D<double>> &k, bool spin_down, int label)

returns the self-energy associated with periodized Green function at a given frequency and for an array of wavevectors

Computes the self-energy of the periodized Green function at a frequency and array of wavevectors.

Parameters:

spin_down – true if the spin-down sector is covered (mixing = 4)
