  • Dirk-Mathys, Spangenberg   Dudley, Angela   Neethling, Pieter H.   Rohwer, Erich G.   Forbes, Andrew (Optical Society of America, 2014-05)
    Spatial light modulators are ubiquitous tools for wavefront control and laser beam shaping but have traditionally been used with monochromatic sources due to the inherent wavelength dependence of the calibration process ...
  • Scholtz, F. G.   Bartlett, Bruce H.   Geyer, H. B. (American Physical Society (APS), 2003-08)
    We show that Wegner’s flow equations, as recently discussed in the Lipkin model, can be solved selfconsistently. This leads to a nonlinear differential equation which fully determines the order parameter as a function ...
  • Baricholo, Peter   Hlatywayo, Dumisani J.   Von Bergmann, Hubertus M.   Stehmann, Timo   Rohwer, Erick   Collier, Mike (ASSAF -- Academy of Science of South Africa, 2011-11)
    A dielectric barrier discharge excited neutral argon (Ar I) excimer lamp has been developed and characterised. The aim of this study was to develop an excimer lamp operating at atmospheric pressure that can replace mercury ...

    As a group of young scientists whose future careers depend increasingly on access to Internet resources, we are extremely concerned by the apparent lack of understanding of the stranglehold that current approaches to ...
  • Ombinda-Lemboumba, S.   Du Plessis, A.   Sparrow, R. W.   Molukanele, P.   Botha, L. R.   Rohwer, E. G.   Steenkamp, C. M.   Van Rensburg, L. (Academy of Science of South Africa (ASSAf), 2009-10)
    Measurements of ultrafast transient processes, of temporal durations in the picosecond and femtosecond regime, are made possible by femtosecond pump probe transient absorption spectroscopy. Such an ultrafast pump probe ...
  • Bohm, Lothar (Academy of Science of South Africa (ASSAf), 2010-03)
    Recent weeks have seen an embarrassing display of heavy-handed National Research Foundation (NRF) management in connection with the Square Kilometer Array (SKA) project – a new $2 billion radio astronomy facility to be ...
