WebDec 26, 2024 · We check the accuracy of the constrained random phase approximation (cRPA) downfolding scheme by considering one-dimensional two- and three-orbital Hubbard models with a target band at the Fermi level and one or two screening bands away from the Fermi level. 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.
