Description

We compare different approaches to the determination of the effective interaction parameters of Hubbard Hamiltonians within the constrained random phase approximation (CRPA) from ab-initio calculations. In addition, we investigate the dependence of the interaction parameters on the choice of the local bases, such as maximally localized Wannier functions (MLWF) and linear combination of atomic orbitals (LCAO).
