A new challenge for time-dependent density functional theory [PDF]
Time-dependent density functional theory is thought to work well for the test cases of He and Be atoms. We perform a quantum defect analysis of the s, p, and d Rydberg states of Be with accurate ground state Kohn-Sham potentials.

Time-dependent density-functional theory. [PDF]
Time-dependent density functional theory (TDDFT) can be viewed as an exact reformulation of timedependent quantum mechanics, where the fundamental variable is no longer the many-body wave-function but the density.

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

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

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

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