Uniform electron gas from two-particle wavefunctions
Paola Gori-Giorgi
An approximation for the unknown two-electron wavefunctions (geminals) of the interacting uniform electron gas is found, starting from the effective screened Coulomb potential prop…

Two-dimensional electron gas: correlation energy versus density and spin polarization
Paola Gori-Giorgi, Claudio Attaccalite, Saverio Moroni +1
We propose a simple analytic representation of the correlation energy for the two-dimensional electron gas, as a function of the density and the spin polarization. This new paramet…
