  • Shearing radiative collapse with expansion and acceleration 
    Thirukkanesh, S.; Rajah, S. S.; Maharaj, S. D. (Journal of Mathematical Physics, 2012)
    We investigate the behaviour of a relativistic spherically symmetric radiative star with an accelerating, expanding and shearing interior matter distribution in the presence of anisotropic pressures. The junction condition ...
  • Some new static charged spheres 
    Maharaj, S. D.; Thirukkanesh, S. (Nonlinear Analysis- Real World Applications, 2009)
    We present new exact solutions for the Einstein-Maxwell system in static spherically symmetric interior spacetimes. For a particular form of the gravitational potentials and the electric field intensity, it is possible ...
  • Spherically symmetric static matter configurations with vanishing radial pressure 
    Thirukkanesh, S.; Govender, M; Lortan, D. B (International Journal of Modern Physics, 2015)
    We present a new family of spherically symmetric, static solutions of the Einstein field equations in isotropic, comoving coordinates. The radial pressure at each interior point of these models vanishes yet equilibrium is ...
  • Strange star model with Tolmann IV type potential 
    Thirukkanesh, S.; Ragel, F. C. (Astrophysics and Space Science, 2014)
    We report a general solution in one of the gravitational potentials to the Einstein system in static spherically symmetric spacetime, modeling anisotropic strange quark matter by imposing a linear barotropic equation of ...
  • Superconductivity and Quantum Criticality in Cr100-zOsz alloys 
    Fernando, P. R.; Sheppard, C. J.; Prinsloo, A. R. E. (Journal of Acta Physica Polonica A, 2016)
    The magnetic phase diagrams of Cr alloys with group-8 metals, such as Re and Ru, show interesting properties. These include quantum critical and superconducting behavior. In order to extend these investigations this ...
  • Transition from dense Kondo to the intermediate-valence regime in the Ce (Pt1-xNix)2Si2 alloys 
    Ragel, F. C.; P de V du Plessis (Journal of Physics: Condensed Matter, 2004)
    Electrical resistivity ρ(T) measurements on polycrystalline samples of the Ce (Pt1−xNix)2Si2 system exhibit dense Kondo behaviour for alloys with . The temperature at which a maximum appears in ρ(T) shifts from Tmax = 65 ...
