A simple self-interaction correction to RPA-like correlation energies
Tim Gould, Adrienn Ruzsinszky, John P. Perdew
The random phase approximation (RPA) is exact for the exchange energy of a many-electron ground state, but RPA makes the correlation energy too negative by about 0.5 eV/electron. T…

coefficients and dipole polarizabilities for all atoms and many ions in rows 1-6 of the periodic table
Tim Gould, Tomas Bucko
Using time-dependent density functional theory (tdDFT) with exchange kernels we calculate and test imaginary frequency-dependent dipole polarizabilities for all atoms and many ns i…
