Real-time electron dynamics with exact-exchange time-dependent density-functional theory [PDF]

open access: yes, 2007
The exact exchange potential in time-dependent density-functional theory is defined as an orbital functional through the time-dependent optimized effective potential (TDOEP) method.

Wavelet-Based Linear-Response Time-Dependent Density-Functional Theory

open access: yes, 2011
Linear-response time-dependent (TD) density-functional theory (DFT) has been implemented in the pseudopotential wavelet-based electronic structure program BigDFT and results are compared against those obtained with the all-electron Gaussian-type orbital ...

Analysis of Floquet formulation of time-dependent density-functional theory [PDF]

open access: yes, 2006
Floquet formulation of time-dependent density-functional theory is revisited in light of its recent criticism [Maitra and Burke, Chem. Phys. Lett. 359 (2002), 237].

Comparing time-dependent density functional theory with many-body perturbation theory for semiconductors: Screened range-separated hybrids and the GW plus Bethe-Salpeter approach

open access: yesPHYSICAL REVIEW MATERIALS, 2019
We present band structure and optical absorption spectra obtained from density functional theory (DFT) and linear response time-dependent DFT (TDDFT) calculations using a screened range-separated hybrid (SRSH) functional, including spin-orbit coupling ...

Global fixed point proof of time-dependent density-functional theory

open access: yes, 2011
We reformulate and generalize the uniqueness and existence proofs of time-dependent density-functional theory. The central idea is to restate the fundamental one-to-one correspondence between densities and potentials as a global fixed point question for ...

Stochastic time-dependent current-density functional theory: a functional theory of open quantum systems

open access: yes, 2008
The dynamics of a many-body system coupled to an external environment represents a fundamentally important problem. To this class of open quantum systems pertains the study of energy transport and dissipation, dephasing, quantum measurement and quantum ...

Enhancing the applicability of multicomponent time-dependent density functional theory.

open access: yesJournal of Chemical Physics, 2019
The multicomponent extension of time-dependent density functional theory (TDDFT) within the nuclear-electronic orbital (NEO) framework enables the calculation of both electronic and vibrational excitations simultaneously.

Multicomponent Time-Dependent Density Functional Theory: Proton and Electron Excitation Energies.

open access: yesJournal of Physical Chemistry Letters, 2018
The quantum mechanical treatment of both electrons and protons in the calculation of excited state properties is critical for describing nonadiabatic processes such as photoinduced proton-coupled electron transfer.
