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

returns the V matrix at a given frequency and wavevector

Computes the V matrix at a given frequency and wavevector.

Parameters:

• spin_down – true if the spin-down sector is covered

• w – complex frequency

• k – wavevector in the physdual basis
