Quasi-Lie schemes and Emden--Fowler equations
J. F. Cariñena, P. G. L. Leach, J. de Lucas
The recently developed theory of quasi-Lie schemes is studied and applied to investigate several equations of Emden type and a scheme to deal with them and some of their generalisa…
An emergent universe supported by a nonlinear sigma model
A. Beesham, S. V. Chervon, S. D. Maharaj
We suggest the use of a nonlinear sigma model as the source which supports an emergent universe. The two-component nonlinear sigma model is considered as the simplest model contain…
Stochastic Wave-Function Unravelling of the Generalized Lindblad Master Equation
Mervlyn Moodley, Francesco Petruccione
Recently a generalized master equation was derived that extends the Lindblad theory to highly non-Markovian quantum processes (H.-P. Breuer, Phys. Rev. A \textbf{75}, 022103 (2007)…
Some new static charged spheres
S. D. Maharaj, S. Thirukkanesh
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 el…
Influence of low-level Pr substitution on the superconducting properties of YBa2Cu3O7-delta single crystals
A. Kortyka, R. Puzniak, A. Wisniewski +4
We report on measurements on Y1-xPrxBa2Cu3O7-delta single crystals, with x varying from 0 to 2.4%. The upper and the lower critical fields, Hc2 and Hc1, the Ginzburg-Landau paramet…
Charged anisotropic matter with linear equation of state
S. Thirukkanesh, S. D. Maharaj
We consider the general situation of a compact relativistic body with anisotropic pressures in the presence of the electromagnetic field. The equation of state for the matter distr…
