Density gradients for the exchange energy of electrons in two dimensions
S. Pittalis, E. Rasanen, J. G. Vilhena +1
We derive a generalized gradient approximation to the exchange energy to be used in density functional theory calculations of two-dimensional systems. This class of approximations…

Local correlation functional for electrons in two dimensions
S. Pittalis, E. Rasanen, M. Marques
We derive a local approximation for the correlation energy in two-dimensional electronic systems. In the derivation we follow the scheme originally developed by Colle and Salvetti…
