Absurdum of the Hohenberg - Kohn Theorem for Many - Electron Coulomb Systems

نویسنده

  • Eugene S. KRYACHKO
چکیده

It is shown that, for isolated many-electron Coulomb systems with Coulombic external potentials, the usual reductio ad absurdum proof of the Hohenberg-Kohn theorem is unsatisfactory since the to-be-refuted assumption made about the one-electron densities and the assumption about the external potentials are not compatible with the Kato cusp condition. The theorem is, however, provable by more sophisticated means and it is shown here that the Kato cusp condition actually leads to a satisfactory proof.

On the Proof by Reductio ad Absurdum of the Hohenberg-Kohn Theorem for Ensembles of Fractionally Occupied States of Coulomb Systems

It is demonstrated that the original reductio ad absurdum proof of the generalization of the Hohenberg-Kohn theorem for ensembles of fractionally occupied states for isolated many-electron Coulomb systems with Coulomb-type external potentials by Gross et al. [Phys. Rev. A 37, 2809 (1988)] is selfcontradictory since the to-be-refuted assumption (negation) regarding the ensemble one-electron dens...

Reply to Comment on " on the Original Proof by Reductio Ad Absurdum of the Hohenberg-kohn Theorem for Many-electron Coulomb Systems "

Any mathematical proof is a game. As a game, it is based on a definite set of rules of logic reasoning which altogether constitutes the subject of logic. One of the simplest rules of the theory of logic is a denial of the truth of a given proposition that is expressed as a sentence. The truth of a proposition has to be denied by asserting its negation. Assuming, for example, that the propositio...

Hohenberg-Kohn theorem for the lowest-energy resonance of unbound systems.

We show that under well-defined conditions the Hohenberg-Kohn theorem (HKT) that provides the foundation of ground-state density functional theory (DFT) can be extended to the lowest-energy resonance of unbound electronic systems. The extended version of the HKT provides an adequate framework to carry out DFT calculations of negative electron affinities.

5 J ul 2 00 6 1 - Density Operators and Algebraic Version of The Hohenberg - Kohn Theorem

Interrelation of the Coleman's representabilty theory for 1-density operators and abstract algebraic form of the Hohenberg-Kohn theorem is studied in detail. Convenient realization of the Hohenberg-Kohn set of classes of 1-electron operators and the Coleman's set of ensemble representable 1-density operators is presented. Dependence of the Hohenberg-Kohn class structure on the boundary properti...

Superfluid LDA (SLDA): Local Density Approximation for Systems with Superfluid Correlations

The theorem of Hohenberg and Kohn 1 concerning the existence of a universal Energy Density Functional (EDF), and its subsequent implementation as a Local Density Approximation (LDA), lead to a new qualitative approach to the study of electron systems, from atoms, to molecules, to condensed matter systems and macromolecules in particular and other fermionic systems in general. Even though neithe...
