Exchange-energy functionals for finite two-dimensional systems
S. Pittalis, E. Rasanen, N. Helbig +1
Implicit and explicit density functionals for the exchange energy in finite two-dimensional systems are developed following the approach of Becke and Roussel [Phys. Rev. A 39, 3761…

Open shells in reduced-density-matrix-functional theory
N. N. Lathiotakis, N. Helbig, E. K. U. Gross
Reduced-density-matrix-functional theory is applied to open-shell systems. We introduce a spin-restricted formulation by appropriately expressing approximate correlation-energy fun…
