TL;DR: This article presents the projector augmented-wave (PAW) method as implemented in the GPAW program package using a uniform real-space grid representation of the electronic wavefunctions and implements the two common formulations of TDDFT, namely the linear-response and the time propagation schemes.
Journal ArticleDOI
Kohn-Sham potential with discontinuity for band gap materials
TL;DR: In this article, a generalized gradient approximation (GGA) energy density is used to model the exchange-correlation hole and the response of the hole-to-density variations is evaluated by using the common-denominator approximation and homogeneous electron-gas-based assumptions.
Journal ArticleDOI
Atomic and electronic structures of N interstitials in GaAs
TL;DR: In this article, the effects of the single nitrogen atom and nitrogen dimer related interstitial defects on the atomic and electronic structures of GaAs have been studied using the density functional theory (DFT).
Journal ArticleDOI
Electronic Structure and Absorption Spectrum of Disperse Red 1: Comparison of Computational Approaches
Jussi Ojanen,Tapio T. Rantala +1 more
TL;DR: In this paper, an azobenzene molecule Disperse Red 1 with strongly delocalized frontier orbitals has been studied with a number of density functional theory (DFT) related approaches.
