This review explains the relationship between density functional theory and strongly
correlated models using the simplest possible example, the two-site Hubbard model. The …

We present the theory of semilocal exchange‐correlation (XC) energy functionals which
depend on the Kohn–Sham kinetic energy density (KED), including the relevant class of …

The most challenging scenario for Kohn-Sham density-functional theory, that is, when the
electrons move relatively slowly trying to avoid each other as much as possible because of …

We use the exact strong-interaction limit of the Hohenberg-Kohn energy density functional to
approximate the exchange-correlation energy of the restricted Kohn-Sham scheme. Our …

A single-term density functional model for the left–right nondynamic/strong electron
correlation is presented based on single-determinant Kohn–Sham density functional theory …

Improving the accuracy and thus broadening the applicability of electronic density functional
theory (DFT) is crucial to many research areas, from material science, to theoretical …

We have tested the original interaction-strength-interpolation (ISI) exchange-correlation
functional for main group chemistry. The ISI functional is based on an interpolation between …

Using the dual Kantorovich formulation, we compute the strictly correlated electrons (SCE)
functional (corresponding to the exact strong-interaction limit of density functional theory) for …

We use the exact strong-interaction limit of the Hohenberg-Kohn energy density functional to
construct an approximation for the exchange-correlation term of the Kohn-Sham approach …

Approximate exchange–correlation functionals built by modeling in a nonlinear way the
adiabatic connection (AC) integrand of density functional theory have many attractive …
