The Projector-Augmented-Wave method The number of plane waves needed to describe • tightly bound (spatially strongly localized) states, • and rapid oscillations (nodal features) of the orbitals near the nucleus exceeds any practical limit, except maybe for Li and H. The common solution: • Introduce the frozen core approximation:
