چکیده
A new Density-Functional (DF) formula is constructed for atoms. The kinetic energy of the electrons is divided into two parts: the kinetic self-energy and the orthogonalization energy where these concepts are borrowed from the pseudopotential theory. For the radial part of the orthogonalization energy which replaces the radial part of the Fermi-energy of the Thomas-Fermi model we derived the expression 1 °°

The Effect of Substitution of a Zn Atom in Cdn-1TenClusters (n=1-10)
In this research, structural and electronic properties of ZnCdn-1Ten clusters (n=1-10) have been studied by formalism of density functional theory and using the projector augmented wave within local density approximation. The structural properties (such as bond length/angle and coordination number), electronic and optical properties (such as binding energy, Kohn-Sham spect...
متن کاملTime-dependent density-functional approach for exciton binding energies
Optical processes in insulators and semiconductors, including excitonic effects, can be described in principle exactly using time-dependent density-functional theory TDDFT . Starting from a linearization of the TDDFT semiconductor Bloch equations in a two-band model, we derive a simple formalism for calculating exciton binding energies. This formalism leads to a generalization of the standard W...
متن کاملStark Ionization of Atoms and Molecules within Density Functional Resonance Theory
We show that the energetics and lifetimes of resonances of finite systems under an external electric field can be captured by Kohn–Sham density functional theory (DFT) within the formalism of uniform complex scaling. Properties of resonances are calculated self-consistently in terms of complex densities, potentials and wavefunctions using adapted versions of the known algorithms from DFT. We il...
متن کاملA Simplified Approach to the Density Functional Theory of Molecules
A simplified molecular orbital (MO) formalism based on density functional theory is developed. Starting from the same energy expression as Kohn-Sham theory the electronic density is expanded in terms of atomic mono-center densities. Application of the variational principle leads to a secular matrix with a particularly transparent structure which allows the definition of a resonance integral tak...
متن کاملNonuniqueness and derivative discontinuities in density-functional theories for current-carrying and superconducting systems
Current-carrying and superconducting systems can be treated within density-functional theory if suitable additional density variables ~the current density and the superconducting order parameter, respectively! are included in the density-functional formalism. Here we show that the corresponding conjugate potentials ~vector and pair potentials, respectively! are not uniquely determined by the de...
متن کاملFirst-principles derivation of density-functional formalism for quenched-annealed systems.
We derive from first principles (without resorting to the replica trick) a density-functional theory for fluids in quenched disordered matrices (QA-DFT). We show that the disorder-averaged free energy of the fluid is a functional of the average density profile of the fluid as well as the pair correlation of the fluid and matrix particles. For practical reasons it is preferable to use another fu...
