Density functional theory for a single excited state is presented using Kato's theorem and the concept of adiabatic connection. The degenerate case is also detailed. The optimized potential method is generalized. The generalized Krieger, Li, and Ž . Iafrate KLI approximation is derived.
A multigrid method for real-space solution of the Kohn᎐Sham equations is presented. By using this multiscale approach, the problem of critical slowing down typical of iterative real-space solvers is overcome. The method scales linearly in computer time with the number of electrons if the orbitals ar
The theoretical description of charge distribution, and related properties, such as chemical reactivity descriptors of chemical compounds, has Ž . greatly benefited from the development of density functional theory DFT methods. Indeed, most concepts stemmed from DFT but, up to now, they have been us
