matrix<complex<double>> ED::Green_function(const complex<double> &z, bool spin_down, const size_t label, bool blocks)¶
function that evaluates the one-body Green function 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) blocks : true if in irreducible representations basis output : the Green function matrix
