Separation of the exchange-correlation potential into exchange plus correlation: An optimized effective potential approach.
Most approximate exchange-correlation functionals used within density-functional theory are constructed as the sum of two distinct contributions for exchange and correlation. Separating the exchange component from the entire functional is useful since, for exchange, exact relations exist under uniform density scaling and spin scaling. In the past, accurate exchange-correlation potentials have b...
متن کاملRotational g Tensors Calculated Using Hybrid Exchange-Correlation Functionals with the Optimized Effective Potential Approach.
The calculation of rotational g tensors using density functional theory (DFT) with hybrid exchange-correlation functionals is considered. A total of 143 rotational g tensor elements in 58 molecules (67 isotopic combinations) are calculated using three standard hybrid functionals. Tensor elements determined using an uncoupled approach with orbitals and eigenvalues calculated from the multiplicat...
متن کاملOptimized effective potential method with exact exchange and static RPA correlation
We present a new density-functional method of the self-consistent electronicstructure calculation which does not exploit any local density approximations (LDA). We use the exchange-correlation energy which consists of the exact exchange and the correlation energies in the random-phase approximation. The functional derivative of the correlation energy with respect to the density is obtained with...

Current-Dependent Exchange-Correlation Potential for Dynamical Linear Response Theory.
The frequency-dependent exchange-correlation potential, which appears in the usual Kohn-Sham formulation of a time-dependent linear response problem, is a strongly nonlocal functional of the density, so that a consistent local density approximation generally does not exist. This problem can be avoided by choosing the current-density as the basic variable in a generalized Kohn-Sham theory. This ...
