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 ... -
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 -
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 ... -
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 ... -
Development and performance evaluation of a prototype bio-optical sensor for in-water applications.
(2012)No abstract available. -
The development and testing of computer-aided teaching tools - addressing the conceptual and practical difficulties experienced by first year physics students.
(2002)There has been a great deal of research, both locally and abroad, conducted on the learning practices of students at school and at tertiary levels. In an attempt at improving the status of education, some educators have ... -
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 ... -
Development of near real time and cumulative GIC proxy indices.
(2021)Geomagnetic storms are phenomena which can give rise to geomagnetically induced currents (GICs), which have an adverse effect on technology in that they can cause anomalous low frequency currents that damage critical ... -
Devices for the construction of a cold atom experiment.
(2013)The experimental setup for laser cooling and trapping of 87Rb atoms with the aid of a Magneto-optical trap (MOT) is discussed. The experiment has a diverse setup, which includes: a vacuum system in which the cooling and ... -
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 ... -
Dissipative gravitating systems.
(2011)In this thesis we investigate the effect of shear on radiating stars undergoing gravitational collapse. The interior spacetime is described by the most general spherically symmetric line element in the absence of rotation. ... -
Dynamics and thermalization of a fermion in a fermionic bath embedded in a bosonic bath.
(2013)We consider a model consisting of a finite number of quantum dots each of which confines a spinless electron. We zoom in on a single quantum dot containing an electron of interest treating it as being strongly coupled ... -
The effect of antisymmetrization in diquark models of baryons.
(1997)In this thesis the effect of antisymmetrization in diquark models of baryons composed of light (u and d) quarks is investigated. The diquark in this study is considered alternately as a pointlike and as a composite ... -
The effect of the f-component of the pseudopotential on selected properties of 5d transition metal systems
(2008)Cohesive energies, bulk moduli, and equilibrium lattice constants have been calculated for the 5d transition atoms (Hf, Ta, W, Re, Os, Ir and Pt) in face–centred cubic crystal lattices. We have used the ab initio ...
