Quasiparticle spinors in light-matter interactions: generalized Jaynes-Cummings and antiJaynes-Cummings models
(Research gate, 2020)
Seeking a clear understanding of the physical nature of quasiparticle excitations formed in the JaynesCummings and antiJaynes-Cummings interaction mechanisms in the quantum Rabi model, we have introduced appropriate composite ...
Shell structure of the SU (N) generator spectrum: interpretation as spin angular momentum operators
(Research gate, 2020)
We have established that SU(N) symmetry group generators occur in a spectrum with a
quantum structure composed of N − 1 configuration shells each containing a definite number of
symmetric and antisymmetric pairs of ...
Determining SU (N) symmetry group generators
(Research gate, 2018)
SU(N) symmetry groups are useful in formulating gauge theories of elementary particle interactions
in quantum field theory. Gauge bosons and particle states are associated with the symmetry group
generators. The accuracy ...
SU (N) generator spectrum
(Research gate, 2018)
This paper provides an accurate mathematical method for determining SU(N) symmetry group generators in a general N-dimensional quantum state space. We identify the generators as well-defined quantum
state transition and ...
First Order Expectation Values of Electron Correlation Operators for Two-Electron Atoms
(SPG, 2015)
Simple analytic first-order wave functions corresponding to two-electron atoms electron correlation operators are
obtained by reduction of the Rayleigh-Schrödinger first order perturbation equation to that of one-electron ...
Symmetry Dependent Analytical Pseudopotential for Helium Atom
(2019-11-11)
Electron-electron interaction is the origin of the many-body problems usually encountered in physics and chemistry. Helium atom and other two-electron
systems are the simplest many-body systems in nature. The Schr¨odinger ...
Analytical Absorption Cross-Section for Photon by a Hydrogen 2s Atom
(IOP Publishing, 2011-04)
We calculate the absorption cross-section for photon by a hydrogen 2s atom using the quantum-classical approximation for the total photo cross-section of many electron atoms. With the application of the first-order term ...
Quiet Time Correlation Between Geomagnetic Field Variations and the Dynamics of the East African Equatorial Ionosphere
(Science Publishing Group, 2017)
The equatorial ionosphere is highly dynamic and consequently poses serious threats to communication and
navigation systems. As a result, proper understanding of ionospheric dynamics is important. The present paper presents ...
Variability of VTEC Gradient and TEC Rate Index Over Kisumu, Kenya During Selected Quiet and Storm Days of 2013 and 2014
(Science Publishing Group, 2019)
Vertical Total electron content (VTEC) gradient or rate of change of TEC (ROT) and total electron content (TEC)
rate index or rate of change of TEC index (ROTI) can directly be estimated from receiver independent exchange ...
Quiet Time Geomagnetic Field Variations in the Equatorial East African Region During the Inclining Phase of Solar Cycle 24
(Science Publishing Group, 2014)
In the present paper, geomagnetic field data obtained from magnetometer measurements at two ground based
stations have been used to study solar activity dependence of the solar quiet variations. The study has focused on ...
