A new correlation measure, the product of the Shannon entropy power and the Fisher information of the electron density, is introduced by analyzing the Fisher-Shannon information plane of some two-electron systems (He-like ions, Hooke's atoms). The uncertainty and scaling properties of this information product are pointed out. In addition, the Fisher and Shannon measures of a finite many-electron system are shown to be bounded by the corresponding single-electron measures and the number of…

Atomic Statistical Complexity

Applications of the Shannon information entropy, Fisher measure, Onicescu energy, and two of the simple statistical complexity measures on atoms are presented using the Hartree-Fock density in

Fisher information and Shannon entropy calculations for two-electron systems

Fisher information is calculated for the ground state of He-isoelectronic series, in position ([Formula: see text]) space. The results are given and discussed as a function of the nuclear charge (Z)

It is found that for electron densities of atoms and molecules the Shannon entropy density is intrinsically related to the electron density and the two forms of the Fisher information density.

Some features of the statistical complexity, Fisher–Shannon information and Bohr-like orbits in the quantum isotropic harmonic oscillator

The Fisher–Shannon information and a statistical measure of complexity are calculated in position and momentum spaces for the wavefunctions of the quantum isotropic harmonic oscillator. We show that

Statistical Complexity and Fisher-Shannon Information. Applications

A statistical measure of complexity and the Fisher-Shannon information product are introduced and their properties are discussed and different applications in discrete and continuous systems are shown.

Shannon entropy and many‐electron correlations: Theoretical concepts, numerical results, and Collins conjecture

In this article, I will discuss the overlap between the concept of Shannon entropy and the concept of electronic correlation. Quantum Monte Carlo numerical results for the uniform electron gas are

Rényi, Fisher, Shannon, and their electron correlation tools for two-electron series

The contour maps and 3D-graphs are used to visualize how the interplay between inter-electronic repulsion and electrons-nuclear charge interaction determines the variation of information entropies as a function of the nuclear charge and the screening parameter.



Shannon-information entropy sum as a correlation measure in atomic systems

The interpretation of the entropy sum as a correlation measure is demonstrated for isoelectronic series via an analytical expression that models the asymptotic behavior of the electronic charge

Ground-state correlation energies for two- to ten-electron atomic ions.

Improved estimates of the nonrelativistic stationary nucleus correlation energies of the ground-state atomic ions with three to ten electrons and up to 20 are derived by combining experimental data and improved calculations with relativistic complete-valence-space Hartree-Fock energies.

Information theoretic inequalities

The authors focus on the entropy power inequality (including the related Brunn-Minkowski, Young's, and Fisher information inequalities) and address various uncertainty principles and their interrelations.
