Exact subsystem time-dependent density-functional theory.

open access: yesJournal of Chemical Physics, 2019
In this communication, we show that coupled subsystem time-dependent density functional theory (subsystem TDDFT) [J. Neugebauer, J. Chem. Phys. 126, 134116 (2007)] in combination with projection-based embedding (PbE) is an exact subsystem theory in the ...

Synthesis of environmentally friendly neonicotinoid insecticide with proper functional properties by theoretical methodologies

open access: yesEcotoxicology and Environmental Safety, 2023
Modern insecticide substitutes using acetylcholine receptors (nAChR) as biochemical targets, such as neonicotinoid insecticides (NNIs), have been extensively researched.

Electron dynamics with real-time time-dependent density functional theory

open access: yes, 2016
Real-time time-dependent functional theory (RT-TDDFT) directly propagates the electron density in the time domain by integrating the time-dependent Kohn–Sham equations.

Investigating interaction-induced chaos using time-dependent density functional theory

open access: yes, 2007
Systems whose underlying classical dynamics are chaotic exhibit signatures of the chaos in their quantum mechanics. We investigate the possibility of using time-dependent density functional theory (TDDFT) to study the case when chaos is induced by ...

Linear-response calculation in the time-dependent density functional theory

open access: yes, 2012
Linear response calculations based on the time-dependent density-functional theory are presented. Especially, we report results of the finite amplitude method which we have recently proposed as an alternative and feasible approach to the (quasiparticle ...
