Quadrature fluctuation energy, effective Hamiltonians, quasi-particle modes and quantum phase transitions in the Rabi and Dicke models
(Research gate, 2017)The main purpose of this article is to provide a simple physically motivated exact analytical procedure for determining effective Rabi and Dicke Hamiltonians, which have so far posed serious challenges in studies of ... -
Conserved excitation number and U(1)-symmetry operators for the anti-rotating (anti-Jaynes-Cummings) term of the Rabi Hamiltonian
(Research gate, 2017)+ hω0sz+ hg (ˆa+ ˆa†)(s++ s−)(1a) where ω, ˆa, ˆa† are the quantized field mode angular frequency, annihilation and creation operators, while ω0, sz, s+, s− are the atomic state transition angular frequency and operators. ... -
A note on momentum and energy conservation in dynamics under arbitrary forces in classical Newtonian and relativistic mechanics
(Research gate, 2018)In teaching mechanics course to first year undergraduate students, I have come across a simple, but very important, gap in the formulation of the principle of conservation of momentum and energy in the dynamics of a body ... -
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 ... -
Photospins in the quantum Rabi model
(Research gate, 2019)This article provides a systematic interpretation of the quantum Rabi model as a model of photospins formed in the atom-field Jaynes-Cummings and anti-Jaynes-Cummings interaction mechanisms. A photospin is a quantized ... -
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 ... -
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 ... -
Food Consumption Patterns, Diversity of Food Nutrients and Mean Nutrient Intake in Relation to HIV/AIDS Status in Kisumu District Kenya
(Taylor & Francis Group, 2009)As the causes and consequences of the AIDS epidemic become clearer, so does the fundamental importance of food and nutritional security for HIV-affected individuals. Even as food insecurity remains a major problem in poor ... -
Anthropometric and Dietary Profile of HIV Sero-positive Patients in Chulaimbo Sub-District Hospital, Kenya.
(TextRoad Publication, 2010)There is lacking information on changes in body composition along with dietary pattern among People Living with HIV/AIDS (PLWHA) attending clinic at Chulaimbo Sub- district hospital, Kenya. In most HIV clinics in Kisumu, ... -
Nutrient Intake and Immune Status of HIV Sero-positive Patients in a Comprehensive Care Clinic at Chulaimbo Sub-district Hospital, Kenya
(Science Publishing Group, 2015)Human immunodeficiency virus (HIV) and nutrition status of human are linked to HIV infection and poor nutrient intake can speed the disease progress. Both macro-and micronutrient deficiencies could impair host immune ... -
Extend Of Adoption Of Corporate Governance Practices In Public Secondary Schools In Kisumu Central Sub-County, Kenya
(International Journal Busniess Quantitative Economics and Applied Management Research, 2016)Corporate governance is an important concept and is defined as the process and structures used to direct and manage business affairs of the company towards enhancing prosperity and corporate accounting. This implies the ... -
Dietary Intake of HIV-seropositive Clients Attending Longisa County Hospital Comprehensive Care Clinic, Bomet County, Kenya
(Taylor & Francis, 2018)Background: Dietary intake of HIV-seropositive persons remains a major concern across various settings around the globe. Inadequate dietary intake, infections and stage of disease progression elicit malnutrition among ... -
Mothers’ Beliefs about Indigenous and Traditional Food Affordability, Availability and Taste are Significant Predictors of Indigenous and Traditional Food Consumption among …
(Cambridge University Press, 2019)Objective: To examine mothers’ and young children’s consumption of indigenous and traditional foods (ITF), assess mothers’ perception of factors that influence ITF consumption, and examine the relationship between perceived ... -
Factors Influencing Knowledge and Attitude Among the Caregivers of Patients with Schizophrenia at Mathari Teaching and Referral Hospital, Kenya

The Question of Elitism, Medium and Audience in African Literature: Examples from Kiswahili Short Story
(Academia.edu, 2014)Since the Makerere Conference of 1962, the question of what is ‘African Literature’ has remained unresolved. To a large extent a great number of scholars led by Ngugi reduced the whole question to that of language. This ... -
Real Effective Exchange Rate Volatility and Its Impact on Foreign Direct Investment in Kenya
