Is size-consistency possible with density functional approximations?
نویسنده
چکیده
Density functional approximations do not provide size-consistent methods, contrary to what is commonly assumed in the literature. The violation is related to degeneracy. Two approaches are discussed to alleviate the problem: symmetry breaking and range separation. 2008 Elsevier B.V. All rights reserved.

Ab-initio study of Electronic, Optical, Dynamic and Thermoelectric properties of CuSbX2 (X=S,Se) compounds
Abstract: In this work we investigate the electronic, optical, dynamic and thermoelectric properties of ternary copper-based Chalcogenides CuSbX2 (X= S, Se) compounds. Calculations are based on density functional theory and the semi-classical Boltzmann theory. Computations have been carried out by using Quantum-Espresso (PWSCF) package and ab-initio pseudo-potential technique. To estimate the e...
متن کاملSize consistency of explicit functionals of the natural orbitals in reduced density matrix functional theory.
We report a size-inconsistency problem for several functionals within reduced density matrix functional theory. Being explicit functionals of the natural orbitals and occupation numbers, instead of the one-body reduced density matrix, many of the approximate functionals are not invariant under unitary transformations in the subspace of degenerate occupation numbers. One such transformation mixe...

متن کاملDoes One-third Scheme of PBE0 Functional Dominate Over PBE0 for Electronic Properties of Transition Metal Compounds?
The one-third paradigm of PBE0 density functional, PBE0-1/3, has shown to be a successful method for various properties. In this paper, the applicability of PBE0-1/3 is put into broader perspective for transition metals chemistry. As a comparative study, the performance of PBE0 and PBE0-1/3 has been assessed for geometries and vibrational frequencies of some transition metal hydrides and transi...
متن کاملCO Adsorption on the V (100) Surface: A Density Functional Study
Adsorption of CO molecule on the Vanadium surface has been studied by using of the DFT method with LANL2DZ,6-31G* and 6-31G** basis sets by GGA approximation of theory. Using periodic first principles simulations we investigate the interaction of oxygen molecule with regular V (100) surface. The limitation of this approach is the use of thin metallic slabs with a limited range for their coverag...
