“…More advanced displays of correlations remain to be developed. The restrictions for L # 0 apply also to the complementary display developed by Rehmus and Berry (1981) in which one radial variable is kept fixed, namely rl, and the probability amplitude is displayed on a (r2, 012) grid (figure 20).…”

Advances over the last twenty years are reported, with the emphasis on describing correlations through the distribution of an electron pair's wavefunction in its configuration space. The symmetry of the Schrodinger equation and its eigenfunctions are thus viewed and found to be important. The radial correlations are more significant for the mechanics of the pair than the angular correlations. Connections with other approaches to the subject are described. Earlier studies concerning doubly excited helium and the hydrogen negative ion are related to Wannier's threshold law for ionisation by electron collision, but these two subjects are not yet fully connected. Recent studies on the alkaline earths and helium negative ion are described and viewed as a prelude to a renewed analysis and interpretation of the optical spectra and electron collisions for atoms with partially filled valence shells, which afford amp!e opportunity for the manifestation of strong correlations.

“…One of the most vivid diagnostics, albeit not easy to extract from experiment, is the spatial distribution of electrons within the atom, particularly in a representation that exhibits the spatial correlation of the electrons. This device was exploited first [20] for the relatively crude doubly-excited states of helium generated by Herrick and Sinanoglu, and then for the ground state and low-lying singly-excited states of helium and the ground state of the H-ion [21]. It was then applied to doubly-excited helium in a systematic manner, specifically to probe for spatial correlations characteristic of collective quantization [22].…”

Symmetry is used to define alternative categorizations to which real atomic and molecular systems may correspond. By constructing idealized models to correspond to limiting cases, it becomes possible to decide what are the best approximations and starting points for making mathematlcal representations of the real systems. Tiffs is illustrated with two examples: atoms with two valence electrons, and multidimensional potential surfaces of atomic clusters. In the first example, the question is whether an independent-particle, quantum analogue of a solar system or a collective, rotor-vibrator model is more appropriate, ht the second example, the problem is finding enough about the multidimensional potential to describe the dynamics of the atomic motion, without becoming overwhelmed with irrelevant data.

“…He argued that the natural line shape contains a zero. Later, the optical absorption spectra of the rare gases have been analyzed [2], while the paper [3] is one of many studies dealing with the mechanism of atomic auto-ionization. A unified approach to the configuration interaction and the influence of strong lasers have been expounded in [4].…”

Quantum correlation and entanglement between an ionizing system and a neighboring atom interacting directly and via a quantized field

et al. 2014

Quantum correlations between two neighbor atoms are studied. It is assumed that one atomic system comprises a single auto-ionizing level and the other atom does not contain any auto-ionizing level. The excitation of both atoms is achieved by the interaction with the same mode of the quantized field. It is shown that the long-time behavior of two atoms exhibits quantum correlations even when the atoms do not interact directly. This can be shown using the optical excitation of the neighbor atom. Also a measure of entanglement of two atoms can be applied after reduction of the continuum to two levels.
