Excitation energies from G{ö}rling-Levy perturbation theory along the range-separated adiabatic connection
Elisa Rebolini, Andrew M. Teale, Trygve Helgaker +2
A G{ö}rling-Levy (GL)-based perturbation theory along the range-separated adiabatic connection is assessed for the calculation of electronic excitation energies. In comparison with…
Uniform magnetic fields in density-functional theory
Erik I. Tellgren, Andre Laestadius, Trygve Helgaker +2
We construct a density-functional formalism adapted to uniform external magnetic fields that is intermediate between conventional Density Functional Theory and Current-Density Func…
Interpolated energy densities, correlation indicators and lower bounds from approximations to the strong coupling limit of DFT
Stefan Vuckovic, Lucas O. Wagner, Andrew M. Teale +1
We investigate the construction of approximated exchange-correlation functionals by interpolating locally along the adiabatic connection between the weak- and the strong-coupling r…
