First principles quantum mechanical studies of iridium : a focus on bulk and surface properties.
Recent high-pressure experiments on iridium show a transition to a 14 atomic layer superlattice structure. Since iridium has a high bulk modulus, it is used in many high-pressure applications, for instance as a gasket for ...
Measurement and computational modelling of intermolecular interactions in fluids.
The molecular theory of the second light-scattering virial coefficient Bp describing the effects of interacting pairs of molecules on the depolarization ratio p of Rayleigh-scattered light is reviewed, both for interacting ...
Theoretical and experimental investigations of the Kerr Effect and Cotton-Mouton Effect.
Mr T. J. Sono, an MSc student during the period January 2001 to January 2003, developed an apparatus to measure the pressure and temperature dependence of the electric-field induced birefringence (or electro-optic Kerr ...
An experimental study of diamond and the nitrogen vacancy centre as a source of single photons.
For applications in Quantum Information and Quantum Key Distribution an on-demand source of single photons is desirable because absolute security is of utmost importance. Photons are quantum systems; hence encoding information ...
Measurement of soil in sugar cane using non-destructive techniques.
The soil being delivered with sugar cane consignments. from the cane fields to the factories, has been a recent cause for concern in the South African sugar industry. The soil impurities increase the wear of processing ...

Measurement and validation of waterlines and surface currents using surf-zone video imaging.
The continuous monitoring of beaches and structures near, or in the surf-zone, has become a vital task from an environmental and economic standpoint. Specifically, the Durban beaches are continually nourished with sand ...
Security and entanglement in differential-phase-shift quantum key distribution.
Quantum key distribution (QKD) aims at the creation of a secret key in the two locations of partners, traditionally Alice and Bob, wishing to communicate in private. A generic QKD protocol utilises a quantum channel and ...
The development and testing of computer-aided teaching tools - addressing the conceptual and practical difficulties experienced by first year physics students.
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 ...
Multi-wavelength study of radio sources in the universe.
This thesis presents a detailed multi-wavelength study of radio sources. A major part of the thesis focuses on radio sources in the FIRST survey while the latter part of the thesis studies low redshift radio galaxies in ...
