The molecular ion can exist in a magnetic field
A. V. Turbiner, N. L. Guevara
A detailed study of the ground state of the Coulomb system $(\al \al e e)$ which corresponds to the molecular ion in a magnetic field G in p…
Shannon entropies of atomic structure factors, off-diagonal order and electron correlation
Robin P. Sagar, Nicolais L. Guevara
Shannon entropies of one- and two-electron atomic structure factors in the position and momentum representations are used to examine the behavior of the off-diagonal elements of de…
A note about the ground state of the hydrogen molecule
A. V. Turbiner, N. L. Guevara
A trial function is presented for the molecule which provides the most accurate (the lowest) Bohr-Oppenheimer ground state energy among few-parametric trial functions (with $…
The molecular ion in a magnetic field in linear parallel configuration
A. V. Turbiner, N. L. Guevara, J. C. López Vieyra
A first detailed study of the ground state of the H molecular ion in linear configuration, parallel to a magnetic field direction, and its low-lying $\Si,Π,\De$ states is car…
Mutual information and electron correlation in momentum space
Robin P. Sagar, Nicolais L. Guevara
Mutual information and information entropies in momentum space are proposed as measures of the non-local aspects of information. Singlet and triplet state members of the helium iso…
The exotic ion in a strong magnetic field. Linear configuration
A. V. Turbiner, J. C. López Vieyra, N. L. Guevara
An accurate study of the lowest and the low-lying excited , , electronic states of the exotic molecular ion in linear configuration par…
