Excitations in time-dependent density-functional theory [PDF]

open access: yesPhysical Review Letters, 2002
An approximate solution to the time-dependent density functional theory (TDDFT) response equations for finite systems is developed, yielding corrections to the single-pole approximation.

Progress in Time-Dependent Density-Functional Theory [PDF]

open access: yesAnnual Review of Physical Chemistry, 2011
The classic density-functional theory (DFT) formalism introduced by Hohenberg, Kohn, and Sham in the mid-1960s, is based upon the idea that the complicated N-electron wavefunction can be replaced with the mathematically simpler 1-electron charge density ...

Quantum-electrodynamical time-dependent density functional theory within Gaussian atomic basis. [PDF]

open access: yesJ Chem Phys, 2021
Inspired by the formulation of quantum-electrodynamical time-dependent density functional theory (QED-TDDFT) by Rubio and co-workers [Flick et al., ACS Photonics 6, 2757-2778 (2019)], we propose an implementation that uses dimensionless amplitudes for ...

Time-dependent density functional theory.

open access: yesAnnual Review of Physical Chemistry, 2004
▪ Abstract  Time-dependent density functional theory (TDDFT) can be viewed as an exact reformulation of time-dependent quantum mechanics, where the fundamental variable is no longer the many-body wave function but the density. This time-dependent density is determined by solving an auxiliary set of noninteracting Schrödinger equations, the Kohn-Sham ...

Time-dependent density functional theory on a lattice [PDF]

open access: yesPhysical Review B, 2012
A time-dependent density functional theory (TDDFT) for a quantum many-body system on a lattice is formulated rigorously. We prove the uniqueness of the density-to-potential mapping and demonstrate that a given density is $v$-representable if the initial ...

Solitons in Nuclear Time-Dependent Density Functional Theory [PDF]

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

Computational complexity of time-dependent density functional theory [PDF]

open access: yesNew Journal of Physics, 2014
Time-dependent density functional theory (TDDFT) is rapidly emerging as a premier method for solving dynamical many-body problems in physics and chemistry. The mathematical foundations of TDDFT are established through the formal existence of a fictitious
