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 ...
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 ...
