Periodic orbits around a spherically symmetric naked singularity
Gulmina Zaman Babar, Adil Zaman Babar, Yen-Kheng Lim
The motion of time-like test particles in the Fisher/Janis-Newman-Winicour (F/JNW) spacetime is studied with the Hamiltonian formulation of the geodesic equations. The spacetime is…
Phase transitions in geometrothermodynamics
H. Quevedo, A. Sanchez, S. Taj +1
Using the formalism of geometrothermodynamics, we investigate the geometric properties of the equilibrium manifold for diverse thermodynamic systems. Starting from Legendre invaria…
Asymptotic Behaviour of the Proper Length and Volume of the Schwarzschild Singularity
Asghar Qadir, Azad A. Siddiqui
Though popular presentations give the Schwarzschild singularity as a point it is known that it is spacelike and not timelike. Thus it has a "length" and is not a "point". In fact,…
Similarities Between Classical Timelike Geodesics in a Naked Reissner-Nordstrom Singularity Background and the Behaviour of Electrons in Quantum Theory
Asghar Qadir, Azad A. Siddiqui
It is generally assumed that naked singularities must be physically excluded, as they could otherwise introduce unpredictable influences in their future null cones. Considering geo…
