Using the Hartree–Fock non-relativistic wave functions in the position and momentum
spaces, the statistical measure of complexity C, due to López-Ruiz, Mancini, and Calbet for …

Fisher–Shannon (FS) and López-Ruiz, Mancini, and Calbet (LMC) complexity measures,
detecting not only randomness but also structure, are computed by using near Hartree–Fock …

The Fisher-Shannon plane which embodies the Fisher information measure in conjunction
with the Shannon entropy is tested in its ability to quantify and compare the informational …

The two‐electron atomic densities are analyzed in both position and momentum spaces in
terms of different information‐theoretic measures, such as disequilibrium, Shannon entropy …

The Fisher divergence (FD) and Jensen–Shannon divergence (JSD) are used in this work
with the aim of providing quantitative measures of the discrepancies between two arbitrary D …

A new entropy measure is proposed for the molecular electronic structure theory. The
corresponding many-electron, Shannon-like measure reflects quantum entanglement …

Position and momentum space Rényi information of order α has been studied within a
Hartree–Fock framework for 103 neutral atoms, 54 singly charged cations and 43 anions in …
