Density-functional theory of the nonlinear optical susceptibility: Application to cubic semiconductors.
We present a general scheme for the computation of the time dependent (TD) quadratic susceptibility (χ(2)) of an extended insulator obtained by applying the ‘2n+ 1’ theorem to the action functional as defined in TD density functional theory. The resulting expression for χ(2) includes self-consistent local-field effects, and is a simple function of the linear response of the system. We compute t...
متن کاملApplication of time-dependent density functional theory to optical activity
As part of a general study of the time-dependent local density approximation (TDLDA), we here report calculations of optical activity of chiral molecules. The theory automatically satisfies sum rules and the Kramers-Kronig relation between circular dichroism and optical rotatory power. We find that the theory describes the measured circular dichroism of the lowest states in methyloxirane with a...
متن کاملAnalytic cubic and quartic force fields using density-functional theory.
We present the first analytic implementation of cubic and quartic force constants at the level of Kohn-Sham density-functional theory. The implementation is based on an open-ended formalism for the evaluation of energy derivatives in an atomic-orbital basis. The implementation relies on the availability of open-ended codes for evaluation of one- and two-electron integrals differentiated with re...
متن کاملFrom Density Functional Theory to Density Matrix Functional Theory
Coupled cluster methods are considered among the most accurate tools in electronic structure theory. Nonetheless relatively limited attempt seems to have been made to extend their applicability to the description of the core-excitation phenomena that are behind largely used spectroscopic techniques like x-ray absorption spectroscopy and x-ray circular dichroism. As a first step to redeem for su...
متن کاملA Density Functional Theory Study of Structure of Phosphonic Acid
The molecular structure of the stable conformation of phosphonic acid in gas phase has beencomputed by employing complete geometry optimization in Density Functional Theory(DFT) methods. The methods used for calculations are B3LYP, BP86 and B3PW91 that havebeen studied in two series of basis sets: D95** and 6-31+G(d,p) for hydrogen and oxygenatoms; LANL2DZ for phosphorus. Bond lengths and angle...
