Spin–orbit couplings within spin-conserving and spin-flipping time-dependent density functional theory: Implementation and benchmark calculations [PDF]

open access: yes, 2022
We present a new implementation for computing spin-orbit couplings (SOCs) within time-dependent density-functional theory (TD-DFT) framework in the stan- dard spin-conserving formulation as well in the spin-flip variant (SF-TD-DFT). This approach employs

Visualizing and Characterizing Excited States from Time-Dependent Density Functional Theory [PDF]

open access: yes, 2023
Time-dependent density functional theory (TD-DFT) is the most widely-used electronic structure method for excited states, due to a favorable combination of low cost and (in many contexts) semi-quantitative accuracy.

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

open access: yesAnnual Review of Physical Chemistry, 2012
The classic density-functional theory (DFT) formalism introduced by Hohenberg, Kohn, and Sham in the mid-1960s is based on the idea that the complicated N-electron wave function can be replaced with the mathematically simpler 1-electron charge density in electronic structure calculations of the ground stationary state.

Can We See the Energy Densities? II. Insights from Linear-Response Time-Dependent Density Functional Theory Calculations [PDF]

open access: yes, 2020
Inspired by the analysis of Kohn-Sham energy densities by Nakai et al, we extended the energy density analysis to linear-response time-dependent density functional theory (LR-TDDFT) calculations.
