The variational method complemented with the use of explicitly correlated Gaussian basis
functions is one of the most powerful approaches currently used for calculating the …

This review article has the antecedents of Jaskolski's 1996 Physics Report on “Confined
Many-electron Systems", the fifteen chapters on the “Theory of Confined Quantum Systems" …

We present a quantum mechanical model capable of describing isotropic compression of
single atoms in a non-reactive neon-like environment. Studies of 93 atoms predict drastic …

Low-dimensional semiconductor structures, often referred to as nanocrystals or quantum
dots, exhibit fascinating behavior and have a multitude of potential applications, especially …

Phenomenological approaches on the basis of simple model potentials for the description of
various situations where the atom is spacially confined, such, eg, as atoms inside a C60-like …

The energy spectra of ground-state, ionized and excited multielectron atoms and ions of the
3d and 4d periods of the periodic table centred in impenetrable spherical confinement are …

This book is an introduction to the physics of highly excited, easily perturbed or interacting
atoms. The book begins with a brief introduction to the traditional view of electron shells and …

The Shannon information entropy of 1-normalized electron density in position and
momentum space S r and S p⁠, and the sum ST⁠, respectively, are reported for the ground …

Many atomic systems exhibit indications of compressed electronic shell: atoms locked in
crystals, solids at cryogenic temperatures, atoms trapped by fullerene cages, and atoms in …

Atomic high-precision measurements have become a competitive and essential technique
for tests of fundamental physics, the Standard Model, and our theory of gravity. It is therefore …
