Additional degrees of freedom associated with position measurements in non-commutative quantum mechanics

Rohwer, C. M. (Christian M.) (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: Due to the minimal length scale induced by non-commuting co-ordinates, it is not clear a priori what is meant by a position measurement on a non-commutative space. It was shown recently in a paper by ...
Application of the relativistic random-phase and distorted wave impulse approximations to quasielastic proton-nucleus scattering

Van Niekerk, David Douglas (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: In this dissertation a fully relativistic model for polarized inclusive quasielastic proton-nucleus scattering is developed. Using a standard relativistic impulse approximation (RIA) treatment of quasielastic ...
The formalism of non-commutative quantum mechanics and its extension to many-particle systems

Hafver, Andreas (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: Non-commutative quantum mechanics is a generalisation of quantum mechanics which incorporates the notion of a fundamental shortest length scale by introducing non-commuting position coordinates. Various ...
Locating the inner edge of a neutron star crust

Van Rooy, Milton William (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: The overall goal of this project is to study neutron star properties and locate the transition density from the core to the crust using fifteen parameter sets of the effective Skyrme nucleon-nucleon interaction ...
Non-commutative quantum mechanics : properties of piecewise constant potentials in two dimensions

Thom, Jacobus D. (Jacobus Daniel) (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: The aim of this thesis is threefold. Firstly, I give an overview of non-commutative quan- tum mechanics and build up a description of non-commutative piecewise constant poten- tial wells in this context. ...
Non-linear effects in quantum electrodynamics

Kohler, Shane Jerome (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: See abstract in full text
Optical second harmonic generation and pump-probe reflectivity measurements from Si/SiO2 interfaces

Nyamuda, Gibson Peter (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: Silicon/silicon dioxide (Si/SiO2) interface is widely used in microelectronics as the gate between the drain and source of most metal oxide semiconductor field effect transistors (MOSFETs). The ...
Relativistic eikonal formalism applied to inclusive quasielastic proton-induced nuclear reactions

Titus, Nortin, P-D (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: In this dissertation we present, for the first time, a relativistic distorted wave impulse approximation formalism to describe quasielastic proton-nucleus scattering. We start from a full many-body ...
Ultrafast electron diffraction : source development, diffractometer design and pulse characterisation

Kassier, Gunther Horst (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: Ultrafast Electron Diffraction (UED) is a rapidly maturing field which allows investigation of the evolution of atomic arrangement in solids on timescales comparable to the vibrational period of their ...
