WebGPAW is a density-functional theory (DFT) Python code based on the projector-augmented wave (PAW) method and the atomic simulation environment . The wave functions can be described with: Plane-waves (pw) Real-space uniform grids, multigrid methods and the finite-difference approximation (fd) Atom-centered basis-functions (lcao) WebThe projector functions are dual to the partial waves: Charge and overlap densities Starting from the completeness relations it is possible to show that, in the PAW method, the total charge density (or more precisely the overlap density) related to two orbitals and can be rewritten as (for details we refer to Ref.
