This is a comprehensive review of the strong-interaction limit of density functional theory. It
covers the derivation of the limiting strictly correlated electrons (SCE) functional from exact …

The main theme of this review is the many-body physics of vortices in quantum droplets of
bosons or fermions in the limit of small particle numbers. Systems of interest include cold …

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 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 …

We address low-density two-dimensional circular quantum dots with spin-restricted Kohn-
Sham density functional theory. By using an exchange-correlation functional that encodes …

We study the Wigner crystallization on partially filled topological flat bands of kagome,
honeycomb and checkerboard lattices. We identify the Wigner crystals (WCs) by analyzing …

We study the quantum phase transition of interacting electrons in quantum wires from a one-
dimensional (1D) linear configuration to a quasi-1D zigzag arrangement using quantum …

We present here an experimental study of Wigner islands formed by electrons floating over
helium. Electrons are trapped electrostatically in a mesoscopic structure covered with a …

We study interaction-induced localization of electrons in an inhomogeneous quasi-one-
dimensional system—a wire with two regions, one at low density and the other high …

Describing the ground states of continuous, real-space quantum many-body systems, like
atoms and molecules, is a significant computational challenge with applications throughout …
