odinger equation many times. The density matrix renormalization group method makes this possible for one-dimensional, real-space systems of more than two interacting electrons. We illustrate and explore the convergence properties of the exact KS scheme for both weakly and strongly correlated systems. We also explore the spin-dependent generalization and densities for which the functional is ill defined. 
Kohn-Sham equations with functionals from the strictly-correlated regime: Investigation with a spectral renormalization method.
Using this method, the Kohn-Sham equations with functionals that include the next leading term in the strong-interaction limit of density functional theory, the so called zero-point energy (ZPE) functional as well as with an interaction-strength-interpolation (ISI) functional that includes both the exact SCE and ZPE terms.
Universal nature of different methods of obtaining the exact Kohn–Sham exchange-correlation potential for a given density
An interesting fundamental problem in density-functional theory of electronic structure of matter is to construct the exact Kohn-Sham (KS) potential for a given density. The exact potential can then
Electron avoidance: A nonlocal radius for strong correlation
We present here a model of the exchange-correlation hole for strongly correlated systems using a simple nonlocal generalization of the Wigner-Seitz radius. The model behaves similarly to the strictly
Numerical methods for the inverse problem of density functional theory
The inverse problem of Kohn–Sham density functional theory (DFT) is often solved in an effort to benchmark and design approximate exchange-correlation potentials. The forward and inverse problems of

. We analyze the inverse problem of Density Functional Theory using a regularized variational method. First, we show that given k and a target density ρ , there exist potentials having k th excited
How to make electrons avoid each other: a nonlocal radius for strong correlation
We present here a model of the exchange-correlation hole for strongly correlated systems using a simple nonlocal generalization of the Wigner--Seitz radius. The model behaves similarly to the
The Hubbard dimer: a density functional case study of a many-body problem.
This review explains the relationship between density functional theory and strongly correlated models using the simplest possible example, the two-site Hubbard model, and explores the behavior of the gap and the many-body Green's function, demonstrating the 'failure' of the Kohn-Sham (KS) method to reproduce the fundamental gap.
Accurate effective potential for density amplitude and the corresponding Kohn–Sham exchange–correlation potential calculated from approximate wavefunctions
Over the past few years it has been pointed out that direct inversion of accurate but approximate ground state densities leads to Kohn-Sham exchange-correlation (xc) potentials that can differ
Guaranteed Convergence of a Regularized Kohn-Sham Iteration in Finite Dimensions.
The exact Kohn-Sham iteration of generalized density-functional theory in finite dimensions with a Moreau-Yosida regularized universal Lieb functional and an adaptive damping step is shown to
One Dimensional Mimicking of Electronic Structure: The Case for Exponentials
An exponential interaction is constructed so that one-dimensional atoms and chains of atoms mimic the general behavior of their three-dimensional counterparts. Relative to the more commonly used


One-dimensional continuum electronic structure with the density-matrix renormalization group and its implications for density-functional theory.
The density matrix renormalization group is extended to compute exact ground states of continuum many-electron systems in one dimension with long-range interactions and finds an interacting, extended system which is an insulator but whose Kohn-Sham system is metallic.

This paper prescribes an orbital construction of the exact local effective potential in the Kohn-Sham self-consistent equations, so that from a given electron density the corresponding exact
Exact Kohn-Sham potential of strongly correlated finite systems.
It is shown that the numerical calculations for a one-dimensional two-electron model system indeed approach and reach the limit and that the functional form of the potential is universal, i.e., independent of the details of the two fragments.
Guaranteed convergence of the Kohn-Sham equations.
A sufficiently damped iteration of the Kohn-Sham (KS) equations with the exact functional is proven to always converge to the true ground-state density, regardless of the initial density or the

A generalization of the numerical renormalization-group procedure used first by Wilson for the Kondo problem is presented. It is shown that this formulation is optimal in a certain sense. As a
Adiabatic approximation in nonperturbative time-dependent density-functional theory.
This work constructs the exact exchange-correlation potential of time-dependent density-functional theory and the approximation to it that is adiabatic but exact otherwise and identifies the regime of high-frequency excitations where the adiABatic approximation breaks down and explicitly calculate the nonadiabatic contribution to the exchange-Correlation potential.
Reference electronic structure calculations in one dimension.
It is demonstrated that large strongly correlated systems provide a theoretical laboratory for studying strong correlation and developing density functional approximations to handle strong correlation, if they mimic three-dimensional reality sufficiently closely.
Time-dependent density-functional theory and strongly correlated systems: insight from numerical studies.
The scope of time-dependent density-functional theory for strongly correlated (lattice) models out of equilibrium and an adiabatic local density approximation to v_(xc) for the 1D Hubbard model is illustrated to gain insight about approximate xc potentials.
Density matrix renormalization group
We give an introduction to Numerical Renormalization Group (NRG) and point out the reason it fails. We then discuss the procedure of the more sophisticated Density Matrix Renormalization Group (DMRG)
