Comparison of direct and Fourier space techniques in time - dependent density functional theory
نویسندگان
چکیده
Several techniques have appeared in the literature to solve the equations of time-dependent density functional theory. We compare the efficiency of different methods based on mesh representations of the wave functions (direct and Fourier space), taking as a test case the calculation of the surface plas-mon in the cluster Na 8. For smaller systems, the methods have comparable efficiency, but for large systems the direct space and time methods have a decided advantage.

Theoretical Study on Structure and Electronic Properties of Aniline-5-Membered Heterocyclic Co-oligomers
With the aim of exploring the electronic and optical properties of some interesting conductive copolymers in view of potential applications, a regular oligomer systems made of aniline and three reference heterocyclic compounds (pyrrole, thiophene and furan) are studied using density functional theory (DFT) and time dependent density functional theory (TDDFT) calculations at B3LYP/6-31+G(d,p) le...
متن کاملPhotosensitizing properties for porphyrazine and some derivatives
We have investigated photosensitizing properties for porphrazine and eleven of its related derivatives based on time-dependent density functional theory (TD-DFT) calculations. The modles have been divided into two categories based on the existence of CN functional group in one category but not in the other one. The other functional groups include H, CH3, F, CF3, C6H5, and C6F5 counterparts. The...
متن کاملFractional Order Generalized Thermoelastic Functionally Graded Solid with Variable Material Properties
In this work, a new mathematical model of thermoelasticity theory has been considered in the context of a new consideration of heat conduction with fractional order theory. A functionally graded isotropic unbounded medium is considered subjected to a periodically varying heat source in the context of space-time non-local generalization of three-phase-lag thermoelastic model and Green-Naghdi mod...
متن کاملStructural Characteristics and Reactivity Relationship of some Thiophene Derivatives
ABSTRACT The application of many hetero-aromatic compounds in pharmaceutical and dye industries make the theoretical study of their dipole moment (µ) oscillator strength (f) and other photo-physical properties worthwhile. These properties determine the solubility of many compounds; predict the relationship between their structures, properties and performance. The f, µ, α, transition dipole mome...
متن کاملAbsorption of DCM Dye in Ethanol: Experimental and Time Dependent Density Functional Study
Experimental and theoretical absorption spectra of [2-[2-[4-(dimethylamino) phenyl]ethenyl]-6-methyl-4H- pyran-4-ylidene]-propanedinitrile (DCM) have been studied. UV-Visible (UV-Vis.) absorption spectrum of DCM has been reported after its synthesis. Two relatively intense peaks appeared at 473 and 362 nm respectively. A theoretical investigation on the electronic structure of DCM is presented ...
