Function Documentation

matrix<complex<double>> ED::self_energy(const complex<double> &z, bool spin_down, const size_t label)

function that evaluates the self-energy at a given complex frequency z : complex frequency spin_down : true if we want the spin-down sector (if the mixing=4) label : label of the model instance (in case there are many) output : the self-energy matrix
