Resistive and viscous convection in a cylindrical plasma
It is shown that the combined effect of resistivity, viscosity, and thermal conductivity leads to large-scale stationary convection. This is done for a cylindrical current-carrying plasma in a shearless magnetic field. ...

On the origin of the optical vortex lattices in a nematic liquid crystal light valve
(OSA - The Optical Society, 2019)
Optical vortices and lattices of these are attracting the attention of the scientific community because of their applications in various fields of optical processing, communications, enhanced imaging systems, and bio-inspired ...
Electron affinities of alkaline-earth-metal atoms
The negative ions of the alkaline-earth-metal atoms (Be to Ba) have been studied by means of a pseudopotential model together with configuration- interaction and multiconfiguration self-consistent-field techniques. Only ...
Introduction of external field effects in the frontier molecular orbital theory of chemical reactivity
External field effects are introduced in both charge and orbital control terms of Klopman–Salem formalism for the study of chemical reactivity in condensed phase. An analytical expression is derived for the change of the ...
Electromagnetically induced cross focusing in a four-level atomic medium
(The Optical Society, 2016-07-05)
We describe cross focusing in a four-level atomic medium under electromagnetically induced transparency. We show that due to the giant Kerr nonlinearity experienced by the atoms, cross focusing between weak signal and probe ...
A correlation‐energy functional from a correlation‐factor model
In this work, a way to approximate the correlation energy functional starting from a model correlation factor is shown. The problem is addressed by using formally exact properties of the second‐order density matrix and ...
Electron affinities of alkaline-earth atoms by means of different density functionals
Various correlation energy density functionals have been used to evaluate the electron affinities of the alkaline-earth atoms. A related approach based on polarization potentials was also tested. The results give evidence ...
On the SCF theory of continuum solvent effects representation: Introduction of local dielectric effects
The introduction of local dielectric effects within the SCF theory of continuum solvent effects representation is examined at a semiempirical level. The formalism is developed in the frame of the reaction field theory ...
Circularly polarized alfven and ion cyclotron waves in space plasmas
The linear and nonlinear theory of circularly-polarized Alfvdn and ion-cyclotron waves in multicomponent plasmas is reviewed. It is shown that minor heavy- ion components play an important role in the dispersive properties ...
