For systems consisting of distinguishable particles, there exists an agreed upon notion of
entanglement which is fundamentally based on the possibility of addressing individually …

Entanglement is nowadays considered as a key quantity for the understanding of
correlations, transport properties and phase transitions in composite quantum systems, and …

The review considers the peculiarities of symmetry breaking and symmetry transformations
and the related physical effects in finite quantum systems. Some types of symmetry in finite …

Based on bipolar dynamic logic (BDL) and bipolar quantum linear algebra (BQLA) this work
introduces bipolar quantum logic gates and quantum cellular combinatorics with a logical …

We compute the entanglement of the ground state and several singlet and triplet excited
states of the helium atom using high-quality, state-of-the-art wavefunctions. The behaviour of …

The Shannon entropy, the desequilibrium and their generalizations (Rényi and Tsallis
entropies) of the three‐dimensional single‐particle systems in a spherically symmetric …

Recently, there has been considerable interest in investigating quantum entanglement in
two-electron systems, such as two-electron model atoms and quantum dots. In this work, the …

Various information theoretic measures, complexities and their inequalities are studied for
hydrogen atom under modified Hulthen potential which is a combination of Hulthen potential …

We investigate the entanglement-related features of the eigenstates of two exactly soluble
atomic models: a one-dimensional three-electron Moshinsky model, and a three …

The ground-state entanglement of a single particle of the N-harmonium system (ie, a
completely integrable model of N particles where both the confinement and the two-particle …
