Structural properties of ground (1 s 2: 1 S e) and first doubly excited resonance (2 s 2: 1 S e)
states of He atom embedded in non-ideal classical plasma (NICP) environment are studied …

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

The effect of geometrical anisotropy is numerically investigated on the linear and nonlinear
optical properties of a GaAs quantum dot which is located at the center of a Ga 1-x Al x As …

Shannon entropy and Fisher information calculated from one-particle density distributions
and von Neumann and linear entropies (the latter two as measures of entanglement) …

We provide benchmark values for Shannon information entropies in position space for the
ground state and ls2s 1Se excited state of helium confined with finite confinement potentials …

Energy eigenvalues of ground and singly excited 1 sns (S 1, 3)(n= 2− 5, being the principal
quantum number) states of a He atom in a quantum dot have been investigated in detail by …

Quantum entanglement for two electrons in the excited states of helium-like atom or ions is
investigated using two-electron wave functions constructed in the B-spline basis. As a …

We examine the entanglement in the ground states of helium and helium-like ions using an
original Hylleraas expansion. The von Neumann and linear entropies of the reduced density …

In this work, we present an investigation on the spatial entanglement entropies in the helium
atom by using highly correlated Hylleraas functions to represent the S-wave states. Singlet …

We study one-dimensional systems of N particles in a one-dimensional harmonic trap with
an inverse power law interaction∼| x|− d. Within the framework of the harmonic …
