Statistical Exchange-Correlation in the Self-Consistent Field
John C. Slater,John C. Slater +1 more
TL;DR: The main point of the method of Gaspar, Kohn, and Sham is that they derived the approximate exchange correction from an approximate Hamiltonian for the system by varying the spin-orbitals to minimize the average value of this Hamiltonians for the ground state as discussed by the authors.

Hole Centers in Halide Lattices
TL;DR: In the case of hole centers, the behavior is dominated by an unoccupied level in the gap, an acceptor level as mentioned in this paper, which is the donor level in semiconductor terminology.

A Simplification of the Hartree-Fock Method
TL;DR: In this article, the Hartree-Fock equations can be regarded as ordinary Schrodinger equations for the motion of electrons, each electron moving in a slightly different potential field, which is computed by electrostatics from all the charges of the system, positive and negative, corrected by the removal of an exchange charge, equal in magnitude to one electron, surrounding the electron whose motion is being investigated.

The Motion of Slow Electrons in a Polar Crystal
T. D. Lee,F.E. Low,David Pines +2 more
TL;DR: In this paper, a variational technique was developed to investigate the low-lying energy levels of a conduction electron in a polar crystal, which is equivalent to a simple canonical transformation, and the use of this transformation enables us to obtain the wave functions and energy levels quite simply.
