Downfolding

WebLöwdin’s downfolding method is a general procedure for solving the eigenvalue problem of a Hamiltonian over a limited subspace of the full Hilbert space. The method is exact and … WebDownfold the Band structure. The method first get the eigenvalues and eigenvectors in a Monkhorst-Pack grid from the model. It then use the scdm-k or the projected wannier function method to downfold the Hamiltonian at each k-point. And finally it Fourier transform the new basis functions(Wannier functions) from k-space to real space.
