Characterisation and quantum application of plasmonic waveguides.
(2016)Plasmonics o ers sub-di raction confinement of light, which a ords enhanced coupling to emitter systems (e.g. quantum dots). This feature makes possible a range of on-chip quantum photonic components - most notably ... -
Characterisation of polarisation-entangled photon source for quantum key distribution.
(2016)Entanglement in real physical systems has been of great interest due to its importance in quantum mechanics. It has applications related to quantum information science speci cally quantum cryptography since it eliminates ... -
Characterization and improvement of a direct solar radiation detector.
(2004)A low-cost Direct Solar Radiation Detector (DSRD) was developed in house in the Department of Physics at the University of KwaZulu-Natal (Westville). A main use of this instrument is to gather solar energy data that are ... -
Chemical pollution arising from heavy inorganic industries in Richards Bay - an assessment.
(2004)The industrial port of Richards Bay on the eastern seaboard of KwaZulu-Natal, South Africa has undergone rapid growth over the last 25 years. This industrial growth has inevitably led to an increase in the anthropogenic ... -
Classical noise in quantum systems.
(2013)Quantum mechanics contains a fresh and mysterious view of reality. Besides the philosophical intrigue, it has also produced and continues to inspire tantalizing new technological innovations. In any technological system, ... -
Clustering analysis for classification and forecasting of solar irradiance in Durban, South Africa.
(2017)Classification and forecasting of solar irradiance patterns has become increasingly important for operating and managing grid-connected solar power plants. A powerful approach for classification of irradiance patterns ... -
Computational and experimental study of thin films of polymer blends.
(2016)Abstract available in PDF file. -
Computational studies of bond-site percolation.
(2007)Percolation theory enters in various areas of research including critical phenomena and phase transitions. Bond-site percolation is a generalization of pure percolation motivated by the fact that bond-site is close to ... -
Computational studies of percolation : determination of the cluster number scaling function for lattices in 2 dimensions.
(2010-09-30)The main aim of this work is to study percolation theory on regular two dimensional -
Computer simulation of nonadiabatic dynamics by means of the quantum-classical Liouville equation.
(2013)Simulation of quantum dynamics for many-body systems is an open area of research. For interacting many-body quantum systems, the computer memory necessary to perform calculations has an astronomical value, so that ... -

(2006)Abstract available in PDF file. -
Constant-temperature dynamics in the Wigner representation of quantum mechanics.
(2011)This dissertation deals with theory and algorithms for computer simulations of classical and quantum systems in the canonical ensemble. First, the approach of Nos e-Hoover and its generalization, known as the Nos e- Hoover ... -
Construction and analysis of the receiver for a solar thermal cooker system.
(2013)One of the key components in a solar thermal cooker system is the receiver since the performance of the receiver greatly affects the entire system. Absorption of the maximum amount of reflected radiation is crucial for ... -
The context of problem tasks in school physical science.
(1999)The purpose of this study was to extend our current knowledge about what happens in physical science classrooms. The focus was the context of problem tasks. This involved the study of the situations, events and factors ... -
Corrosive sulphur in transformers.
(2013)Failures in power transformers, in the majority of cases, have been linked to the formation of copper sulphide (Cu₂S) and corrosive sulphur. Cu₂S is conductive and affects the dielectric properties of the insulation system ... -
The crossfield current-driven ion acoustic instability in a two-ion plasma.
(1987)The behaviour of the crossfield current-driven ion acoustic instability in a plasma containing two ion species is theoretically examined. In our model the electrons are assumed to be hot and the ions cold, i.e. Tₑ »Tᵢ (~ ... -
Determination of quantum entanglement concurrence using multilayer perceptron neural networks.
(2017)Artificial Neural Networks, inspired by biological neural networks, have seen widespread implementations across all research areas in the past few years. This partly due to recent developments in the field and mostly due ... -
