Dielectric function with exact exchange contribution in the electron liquid. II. Analytical expression
Zhixin Qian
The first-order, in terms of electron-interaction in the perturbation theory, of the proper linear response function gives rise to the exchange-contribution to the…
Static dielectric function with exact exchange contribution in the electron liquid
Zhixin Qian
The exchange contribution, , to the static dielectric function in the electron liquid is evaluated exactly. Expression for it is derived analytically in terms of…
Asymptotic behavior of the Kohn-Sham exchange potential at a metal surface
Zhixin Qian
The asymptotic structure of the Kohn-Sham exchange potential in the classically forbidden region of a metal surface is investigated, together with that of the Slate…
Bounds for the second and the third derivatives of the electron density at the nucleus
Zhixin Qian
Lower bound for , the second derivative of the spherically averaged atomic electronic density at the nucleus, and upper bound for , the third derivat…
Asymptotic near nucleus structure of the electron-interaction potential in local effective potential theories
Zhixin Qian, Viraht Sahni
In local effective potential theories of electronic structure, the electron correlations due to the Pauli exclusion principle, Coulomb repulsion, and correlation-kinetic effects, a…
Exchange and correlation near the nucleus in density functional theory
Zhixin Qian
The near nucleus behavior of the exchange-correlation potential in Hohenberg-Kohn-Sham density functional theory is investigated. It is shown that near the nucleu…
