چکیده

We describe a semiempirical method for constructing pseudopotentials for use in correlated wave-function calculations which involves using a combination of calculated and experimental quantities. The pseudopotentials are generated from single-valence-electron configurations and satisfy a norm-conservation condition. Core relaxation and core-polarization effects are taken into account. Detailed results for a typical atom with s and p valence electrons ~silicon! and a transition metal atom ~titanium! are given. The method works very well for silicon but is not satisfactory for titanium.

Systematically convergent basis sets with relativistic pseudopotentials. II. Small-core pseudopotentials and correlation consistent basis sets for the post-d group 16–18 elements

A series of correlation consistent basis sets have been developed for the post-d group 16–18 elements in conjunction with small-core relativistic pseudopotentials of the energy-consistent variety. The latter were adjusted to multiconfiguration Dirac–Hartree–Fock data based on the Dirac–Coulomb–Breit Hamiltonian. The outer-core (n21)spd shells are explicitly treated together with the nsp valence...

Energy-consistent pseudopotentials and correlation consistent basis sets for the 5d elements Hf-Pt.

New relativistic energy-consistent pseudopotentials have been generated for the 5d transition metals Hf-Pt. The adjustment was done in numerical two-component multiconfiguration Hartree-Fock calculations, using atomic valence-energy spectra from four-component multiconfiguration Dirac-Hartree-Fock calculations as reference data. The resulting two-component pseudopotentials replace the [Kr]4d(10...

Optimized norm-conserving Hartree-Fock pseudopotentials for plane-wave calculations

We report Hartree-Fock HF -based pseudopotentials suitable for plane-wave calculations. Unlike typical effective core potentials, the present pseudopotentials are finite at the origin and exhibit rapid convergence in a plane-wave basis; the optimized pseudopotential method A. M. Rappe et al., Phys. Rev. B 41, 1227 1990 improves plane-wave convergence. Norm-conserving HF pseudopotentials are fou...

Going beyond the frozen core approximation: development of coordinate-dependent pseudopotentials and application to Na2(+).

Mixed quantum/classical (MQC) simulations treat the majority of a system classically and reserve quantum mechanics only for a few degrees of freedom that actively participate in the chemical process(es) of interest. In MQC calculations, the quantum and classical degrees of freedom are coupled together using pseudopotentials. Although most pseudopotentials are developed empirically, there are me...
