Abstract: The linear density response of inhomogeneous electronic systems is discussed from a density-functional point of view. We derive a local density approximation for the frequency-dependent exchange-correlation potential which is compared with the ``adiabatic'' expression used in former work.

Carbon-coated MoS2 nanosheets@CNTs-Ti3C2 MXene quaternary composite with the superior rate performance for sodium-ion batteries
TL;DR: In this paper, the authors reported a simple and high-efficient one-pot hydrothermal approach to prepare a unique and stable 1D/2D heterostructure, where ultrathin carbon layer-coated MoS2 nanosheets with large expanded interlayer of 1.02 nm are vertically grown onto the Ti3C2 MXene and cross-linked carbon nanotubes (CNTs), giving rise to a highly conductive 3D network.

Application of quantum chemical methods in polymer chemistry
TL;DR: The rapid development of computational hardware and software, as well as the advances in new theoretical methodologies have allowed quantum chemistry, in particular density functional theory, to be able to be used in computational hardware as discussed by the authors.

Shedding Light on Moire Excitons: A First-Principles Perspective
Hongli Guo,Xu Zhang,Gang Lu +2 more
TL;DR: How vertical electric field can be tuned to control the position, polarity, emission energy, and hybridization strength of the moiré excitons is explored and it is predicted that alternating electric fields could modulate the dipole moments of hybridized moirétons and suppress their diffusion in moirÉ lattices.

Linear response time-dependent density functional theory of the Hubbard dimer
TL;DR: The asymmetric Hubbard dimer was used to study the density-dependence of the exact frequency-dependent kernel of linear-response time-dependent density functional theory as discussed by the authors, and the limitations of the adiabatic approximation utilizing the exact ground-state functional are shown.

Response of finite many‐electron systems beyond the time‐dependent local density approximation: Application to small metal clusters
Jorge M. Pacheco,W. Ekardt +1 more
TL;DR: In this paper, a linear response formalism is developed which is based on density functional theory within the local density approximation, but which is now corrected for its spurious selfinteraction errors, in the way originally proposed by Perdew and Zunger for ground state calculations.

Self-Consistent Equations Including Exchange and Correlation Effects
Walter Kohn,L. J. Sham +1 more
TL;DR: In this paper, the Hartree and Hartree-Fock equations are applied to a uniform electron gas, where the exchange and correlation portions of the chemical potential of the gas are used as additional effective potentials.
Inhomogeneous Electron Gas
P. C. Hohenberg,Walter Kohn +1 more
TL;DR: In this article, the ground state of an interacting electron gas in an external potential was investigated and it was proved that there exists a universal functional of the density, called F[n(mathrm{r})], independent of the potential of the electron gas.

Strongly coupled plasmas: high-density classical plasmas and degenerate electron liquids
TL;DR: Theoretical predictions on the dynamic properties are compared with the x ray and electron scattering data for the metallic electrons as discussed by the authors, and screening effects are analyzed and applied to calculations of the enhancement factor of the thermonuclear reaction rate and the electric resistivity in dense plasmas.

Density-functional approach to local-field effects in finite systems: Photoabsorption in the rare gases
Andrew Zangwill,Paul Soven +1 more
TL;DR: In this article, a density-functional theory for describing polarization-type many-body effects influencing the photoresponse of small electronic systems is presented. But it does not take account of the time-dependent fields induced by an external radiation field.
