Critical Parameterisation of the Brill Wave Initial Value Problem
Andrew Masterson, David Hobill
A numerical framework to explore the Brill Wave Initial Value Problem is presented along with a review of some of the theoretical predictions concerning Brill waves. It is demonstr…
Golden-Ratio-Based Rectangular Tilings
Mark Bryant, David Hobill
A golden-ratio-based rectangular tiling of the first quadrant of the Euclidean plane is constructed by drawing vertical and horizontal grid lines which are located at all even powe…
Self-gravitating charged fluid spheres with anisotropic pressures
Ambrish M. Raghoonundun, David W. Hobill
The coupled system of the spherically symmetric Einstein--Maxwell differential equations is solved under two different source conditions: non-zero electric charge and pressure anis…
The Geometrical Structure of the Tolman VII solution
Ambrish M. Raghoonundun, David W. Hobill
The Tolman~VII solution, an exact analytic solution to the spherically symmetric, static Einstein equations with a perfect fluid source, has many characteristics that make it inter…
Possible Physical Realizations of the Tolman VII solution
Ambrish M. Raghoonundun, David W. Hobill
The Tolman VII solution (an exact static spherically symmetric perfect fluid solution) to the Einstein equations is reexamined, and a closed form equation of state (EOS) is deduced…
Is the Preferred Basis selected by the environment?
Tian Wang, David Hobill
We show that in a quantum measurement, the preferred basis is determined by the interaction between the apparatus and the quantum system, instead of by the environment. This intera…
