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 …

Topology in condensed matter physics manifests itself in the emergence of edge or surface
states protected by underlying symmetries. We review two-dimensional topological …

Using a periodic train of Lorentzian voltage pulses, which generates solitonlike electronic
excitations called levitons, we investigate the charge density backscattered off a quantum …

We present a theory of interacting valence holes in a gate-defined one-dimensional
quantum channel in a single layer of a transition metal dichalcogenide material WSe 2 …

A system of confined charged electrons interacting via the long-range Coulomb force can
form a Wigner crystal due to their mutual repulsion. This happens when the potential energy …

Thermal effects on the total charge density are studied for a one-dimensional correlated
quantum dot by means of the path integral Monte Carlo method. The competition between …

We study a few Fermi atoms interacting through attractive contact forces in a one-
dimensional trap by means of numerical exact diagonalization. From the combined analysis …

We re-adapt a spectral renormalization method, introduced in nonlinear optics, to solve the
Kohn–Sham (KS) equations of density functional theory, with a focus on functionals based …

We assess whether a confined Wigner molecule constituted by 2 N fermions behaves as N
bosons or 2 N fermions. Following the work by Law [Phys. Rev. A 71, 034306 (2005) …

We study the spin ordering of a quantum dot defined via magnetic barriers in an interacting
quantum spin Hall edge. The spin‐resolved density–density correlation functions are …
