the performance of xc functionals whose potential has a correct  asymptotic behavior~\cite{Oliveira_2010} when calculating ionization  potentials and static polarizabilities of atoms, molecules, and  hydrogen chains. In this vein, Andrade and Aspuru-Guzik~\cite{Andrade_2011} proposed a new method where the xc potential is considered as an electrostatic potential generated by a fictitious charge. In terms of this charge, the asymptotic condition is given as a simple condition.
