Screened exchange corrections to the random phase approximation from many-body perturbation theory
Felix Hummel, Andreas Grüneis, Georg Kresse +1
The random phase approximation (RPA) systematically overestimates the magnitude of the correlation energy and generally underestimates cohesive energies. This originates in part fr…
The two-body reduced density matrix of the high-density electron gas
P. Ziesche
For the first time, the cumulant 2-body reduced density matrix (= 2-matrix) of the spin-unpolarized homogeneous electron gas (HEG) is considered. This proves to be the…
The high-density electron gas: How its momentum distribution n(k) and its static structure factor S(q) are mutually related through the off-shell self-energy Sigma(k,omega)
Paul Ziesche
It is shown {\it in detail how} the ground-state self-energy of the spin-unpolarized uniform electron gas (with the density parameter ) in its high-density limit $r_s…
The self-energy of the uniform electron gas in the second order of exchange
P. Ziesche
The on-shell self-energy of the homogeneous electron gas in second order of exchange, , is given by a certain integral…
The 2-matrix of the spin-polarized electron gas: contraction sum rules and spectral resolutions
P. Ziesche, F. Tasnadi
The spin-polarized homogeneous electron gas with densities and for electrons with spin `up' () and spin `down' (), respectively, i…
Reduced density matrices, their spectral resolutions, and the Kimball-Overhauser approach
P. Ziesche, F. Tasnadi
Recently, it has been shown, that the pair density of the homogeneous electron gas can be parametrized in terms of 2-body wave functions (geminals), which are scattering solutions…
