• 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 ...
    • Ultrafast photochromism in metal-organic complexes 

      Von Stein, Xavier (Stellenbosch : Stellenbosch University, 2016-12)
      ENGLISH ABSTRACT : Dithizone (H2Dz), an analytical reagent typically used in colourimetric analysis, reacts with various transition metals to form metal dithizonate complexes. These complexes display strong absorption ...
    • Ultrashort optical pulse characterization 

      Bosman, Gurthwin Wendell (Stellenbosch : University of Stellenbosch, 2008-03)
      Various autocorrelation techniques are employed to characterize ultrashort laser pulses in both the temporal and spectral domain. These techniques are; interference autocorrelation (IAC), modified spectrum autointerfer ...
    • Vacuum polarisation energies of two interacting scalar fields with a mass gap in (1 + 1) dimensions 

      Capraro, Martin Horst (Stellenbosch : Stellenbosch University, 2014-12)
      ENGLISH ABSTRACT: The tools of perturbative Quantum Field Theory are by now a standard part of the theoretical physicist's arsenal. In this thesis we investigate the spectral method, an approach that uses tools from the ...
