Combining density-functional theory and density-matrix-functional theory [PDF]

open access: yesPhysical Review A, 2010
We combine density-functional theory with density-matrix functional theory to get the best of both worlds. This is achieved by range separation of the electronic interaction which permits to rigorously combine a short-range density functional with a long-range density-matrix functional.

Spin in density‐functional theory [PDF]

open access: yesInternational Journal of Quantum Chemistry, 2012
AbstractThe accurate description of open‐shell molecules, in particular of transition metal complexes and clusters, is still an important challenge for quantum chemistry. Although density‐functional theory (DFT) is widely applied in this area, the sometimes severe limitations of its currently available approximate realizations often preclude its ...

Current densities in density-functional theory [PDF]

open access: yesPhysical Review A, 2013
It is well known that any given density rho(x)can be realized by a determinantal wave function for N particles. The question addressed here is whether any given density rho(x) and current density j(x) can be simultaneously realized by a (finite kinetic energy) determinantal wave function.

Nuclear density functional theory

open access: yesAdvances in Physics: X, 2020
The goal of nuclear structure physics is to provide a complete understanding of the static properties of atomic nuclei, their excitation spectra, their response to external fields and their decays.

Toward density functional theory on quantum computers?

open access: yesSciPost Physics, 2023
Quantum Chemistry and Physics have been pinpointed as killer applications for quantum computers, and quantum algorithms have been designed to solve the Schrödinger equation with the wavefunction formalism.

Alchemical perturbation density functional theory

open access: yesPhysical Review Research, 2020
We introduce an orbital-free electron density functional approximation based on alchemical perturbation theory. Given convergent perturbations of a suitable reference system, the accuracy of popular self-consistent Kohn-Sham density functional estimates ...

Solitons in Nuclear Time-Dependent Density Functional Theory

open access: yesFrontiers in Physics, 2020
The soliton existence in sub-atomic many-nucleon systems will be discussed. In many nucleon dynamics represented by the nuclear time-dependent density functional formalism, much attention is paid to energy and mass dependence of the soliton existence. In
