Phase transitions in induced lattice gauge models.
(1995)The present research is based on the study of the phase structure of lattice models incorporating selfinteracting scalars and gauge background fields otherwise known as induced gauge models. Emphasis is placed on the effect ... -
Digital control of light.
(2019)The objective of this research was to describe innovative ways in which digital holography can be applied in controlling laser light. The ability to control and manipulate a laser beam has become an extremely desirable ... -
Non-reversal open quantum walks.
(2015)In this thesis, a new model of non-reversal quantum walk is proposed. In such a walk, the walker cannot go back to previously visited sites but it can stay static or move to a new site. The process is set up on a line using ... -
Photo-switching of dabcyl modified silicon microwire field effect transistors.
(2017)Abstract available in PDF file. -
Development of a post-processing technique for a Quantum Key Distribution system.
(2017)Quantum Information, Processing and Communication (QIPC) is a field concerned with technological implementations established on quantum mechanical phenomena. It is established on the concept that the action of ... -
Numerical simulations of fundamental light-matter interactions.
(2017)We present the results of the numerical investigations of light-matter interactions in one and two dimensions from the quantum mechanical perspective. We investigate the dynamics of two-level systems coupled to quantized ... -
Quantum Key Distribution for the undergraduate curriculum.
(2017)Quantum Key Distribution (QKD) is one of the technological applications of quantum mechanics. The technology allows two users to securely establish an unbreakable key. The key is used to encrypt and decrypt sensitive ... -
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 ... -
Mesosphere-lower thermosphere planetary and tidal waves structure over the southern hemisphere using SANAE and Halley SuperDARN HF radar.
(2015)Abstract available in PDF file. -
Two-level system coupled to a structured environment - a computational study.
(2015)It is well known that analytical solutions to large complex problems are not tractable. Computational or numerical simulations of these types of systems allow one to investigate regimes where analytical methods fail. In ... -
Synthesis, structural and magnetic properties of Nixco1-xFe2O4 and Co(RE)0:1Fe1:9o4 nano-ferrites.
(2017)Abstract available in PDF file. -
Investigation of the relationship between solar radiation and cloud cover using a total sky imager.
(2017)Solar radiometric studies have been done in South Africa, but no research studies have been performed to understand how the cloud fraction (CF) affects the amount of solar radiation received by radiometers. This work focused ... -
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 ...
