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 ...
Multipole expansion of integral powers of cosine theta
(Nature Publishing Group, 2020-11-18)
Legendre polynomials form the basis for multipole expansion of spatially varying functions. The technique allows for decomposition of the function into two separate parts with one depending on the radial coordinates only ...
Symmetry conjugates and dynamical properties of the quantum Rabi model
(Cornell University, 2021)
Symmetry transformations have proved useful in determining the algebraic structure and internal
dynamical properties of physical systems. In the quantum Rabi model, invariance under parity symmetry transformation has been ...
Comparative Investigation of Fullerene PC 71 BM and Non-fullerene ITIC-Th Acceptors Blended With P3HT or PBDB-T Donor Polymers for PV Applications
(Frontiers, 2021)
Fundamentally, organic solar cells (OSCs) with a bulk-heterojunction active layer are
made of at least two electronically dissimilar molecules, in which photoabsorption in one
(donor) generates Frenkel excitons. The ...
The anti-Jaynes-Cummings model is solvable : quantum Rabi model in rotating and counter-rotating frames ; following the experiments
(Cornell University, 2021)
This article is a response to the continued assumption, cited even in reports and reviews of recent experimental breakthroughs and advances in theoretical methods, that the antiJaynes-Cummings (AJC) interaction is an ...
Microstructural and elastic properties of stable aluminium-rich TiAl and TiAl2 formed phase Intermetallics
(North-Holland, 2021)
We studied aluminium-rich Ti-Al (Ti32Al68 and Ti40Al60) binary alloys that were composed of TiAl and
TiAl2 lamellar microstructures. The law of mixtures was employed in calculating the theoretical
Young’s moduli. The ...
Kenya’s response to the COVID-19 pandemic: a balance between minimising morbidity and adverse economic impact
(African Academy of Sciences, 2021)
Coronavirus disease 2019 (COVID-19) has ravaged the world’s socioeconomic systems forcing many governments across the globe to implement unprecedented stringent mitigation measures to restrain its rapid spread and adverse ...
Rabi oscillations, entanglement and teleportation in the anti-Jaynes-Cummings model
(Cornell University, 2021)
This paper provides a scheme for generating maximally entangled qubit states in the anti-JaynesCummings interaction mechanism, so called entangled anti-polariton qubit states. We demonstrate
that in an initial vacuum-field, ...
Annealing efect on the structural and optical behavior of ZnO:Eu3+ thin flm grown using RF magnetron sputtering technique and application to dye sensitized solar cells
(Nature Publishing Group, 2020)
Eu-doped ZnO (ZnO:Eu3+) thin flms deposited by RF magnetron sputtering have been investigated to
establish the efect of annealing on the red photoluminescence. PL spectra analysis reveal a correlation
between the ...
