From the static polarization function of electrons in the random phase approximation, the
quantum Bohm potential for the quantum hydrodynamic description of electrons and the …

We study the wake effect in the induced potential and the stopping power due to plasmon
excitation in a metal slab by a point charge moving inside the slab. Nonlocal effects in the …

Density-functional theory (DFT) is notorious for the absence of gradient corrections to the
two-dimensional (2D) Thomas-Fermi kinetic-energy functional; it is widely accepted that the …

Building on the discussion in Trappe et al.(2016), we present a systematic derivation of
gradient corrections to the kinetic-energy functional and the one-particle density, in …

We present systematic ab initio calculations of the charge carrier correlations between
adjacent layers of two-dimensional materials in the presence of both charged impurity and …

The one-body density matrix (ODM) for a zero temperature non-interacting Fermi gas can be
approximately obtained in the semiclassical regime through different hbar-expansion …

Density-functional theory is utilized to investigate the zero-temperature transition from a
Fermi liquid to an inhomogeneous stripe, or Wigner crystal phase, predicted to occur in a …

A two-dimensional dipolar Fermi gas in a harmonic trap under rotation is studied by solving
ab initio Kohn-Sham equations. The physical parameters used match those of an ultracold …

By using a well-established “ab initio” theoretical approach developed in the past to
quantitatively study the superconductivity of condensed matter systems, based on the Kohn …

The semiclassical ℏ expansion of the one-particle density matrix for a two-dimensional
Fermi gas is calculated within the Wigner transform method of B. Grammaticos and A. Voros …
