Condensation energy of the homogeneous electron gas from density-functional theory for superconductors

Wierzbowska, M and Krogh, Jesper Wisborg LU (2005) In Physical Review B (Condensed Matter and Materials Physics) 71(1). p.1-014509
Abstract
The condensation energy of homogeneous electron gas is calculated within the density-functional theory for superconductors. Purely electronic considerations include the exchange energy exactly and the correlation energy on a level of the random phase approximation. Singlet superconductivity is assumed, and the Coulomb interaction is studied with a model pairing potential at angular momentum up to l=9 and densities 1less than or equal tor(s)less than or equal to10. The homogeneous gas remains nonsuperconducting up to r(s)similar or equal to9. A very weak negative value of the condensation energy has been found for f waves and higher-l pairing at r(s)=10.
