• Ultrafast electron diffraction on the charge density wave compound 4Hb-TaSe2 

      Boshoff, Ilana (Stellenbosch : Stellenbosch University, 2012-03)
      ENGLISH ABSTRACT: Ultrafast electron diffraction is a powerful method to study atomic movement in crystals on sub-picosecond timescales. This thesis consists of three parts. In part one the ultrafast electron diffraction ...
    • Test of fast neutron detectors for spectroscopy with (3He,n) two proton stripping reactions 

      Elbasher, Mohamed Elbasher Ahmed (Stellenbosch : Stellenbosch University, 2012-03)
      ENGLISH ABSTRACT: Nine 100x100x600 mm3 plastic scintillators, formerly built for the neutron time of ight measurements at iThemba LABS, were refurbished. The position resolution of these detectors was determined using ...
    • Statistical thermodynamics of long-range quantum spin systems 

      Olivier, G. J. F. (Gerrit Jacobus Francois) (Stellenbosch : Stellenbosch University, 2012-03)
      ENGLISH ABSTRACT:In this thesis we discuss some of the anomalies present in systems with long-range interactions, for instance negative specifc heat and negative magnetic susceptibility, and show how they can be related ...
    • On evolutionary algorithms for effective quantum computing 

      Kruger, Markus Gustav (Stellenbosch : Stellenbosch University, 2012-03)
      ENGLISH ABSTRACT: The goal of this thesis is to present evolutionary algorithms, and demonstrate their applicability in quantum computing. As an introduction to evolutionary algorithms, it is applied to the simple but ...
    • A non-commutative walecka model as an effective theory for interacting nucleons of finite size 

      Groenewald, Hendrikus Wilhelm. (Stellenbosch : Stellenbosch University, 2012-03)
      ENGLISH ABSTRACT: The nite size of nucleons should play an important role in the description of high density nuclear matter as found in astro-physical objects. Yet we see that the Walecka model, which is generally used ...
    • Density functional calculation of simple molecules 

      Olaoye, Olufemi Opeyemi. (Stellenbosch : Stellenbosch University, 2012-03)
      AFRIKAANSE OPSOMMING: Berekeninge met Density Functional Theory (DFT) is ’n nuttige tegniek om die dinamika van molekules op potensiële energievlakke te verstaan. Beginnende met ’n prototipe molekuul formaldimien, wat ...
