Function Documentation

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

returns the k-dependent lattice one-body matrix $t(k)$, for a multiple wavevector input

Returns the k-dependent one-body matrix t(k) at an array of wavevectors.

Parameters:

• k – array of reduced wavevectors, each in the domain [0,1], like in integrals

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

• label – label of the instance
