Web() is the pseudopotential that acts on the projected component. Different angular momentum states then feel different potentials, thus the HSC norm-conserving pseudopotential is non-local, in contrast to local pseudopotential which acts on all one-particle wave-functions in the same way. ... is the projector augmented wave (PAW) … WebThe projected augmented wave (PAW) pseudopotentials with valence-electron configurations of 1s 1, 2s 2 2p 2, 2s 2 2p 3, 2s 2 2p 4, and 4s 1 3d 8 were employed for H, C, N, O, and Co, respectively. The exchange-correlation interaction was described by generalized gradient approximation (GGA) with the revised Perdew–Burke–Ernzerhof …

The projector augmented wave method (PAW) is a technique used in ab initio electronic structure calculations. It is a generalization of the pseudopotential and linear augmented-plane-wave methods, and allows for density functional theory calculations to be performed with greater computational … See more The linear transformation $${\displaystyle {\mathcal {T}}}$$ transforms the fictitious pseudo wavefunction $${\displaystyle {\tilde {\Psi }}\rangle }$$ to the all-electron wavefunction $${\displaystyle \Psi \rangle }$$ See more • Rostgaard, Carsten (2010). "The Projector Augmented-wave Method". arXiv:0910.1921v2 [cond-mat.mtrl-sci]. • Kresse, G.; Joubert, D. … See more The PAW transformation allows all-electron observables to be calculated using the pseudo-wavefunction from a pseudopotential calculation, conveniently avoiding having to ever represent the all-electron wavefunction explicitly in memory.
