Function Documentation

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

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

Returns the k-dependent one-body matrix t(k) at a given wavevector.

Parameters:

• k – reduced wavevector, 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
