Linearized Stability of Bardeen de-Sitter Thin-Shell Wormholes
Hassan Alshal
A thin-shell wormhole is crafted by the cut-and-paste method of two Bardeen de-Sitter black holes using Darmois-Israel formalism. Energy conditions are considered for different val…
Massive Dual Gravity in N Spacetime Dimensions
H. Alshal, T. L. Curtright
We describe a field theory for "massive dual gravity" in N spacetime dimensions. We obtain a Lagrangian that gives the lowest order coupling of the field to the N-dimensional curl…
Massive Dual Spin 2 Revisited
T. L. Curtright, H. Alshal
We reconsider a massive dual spin 2 field theory in four spacetime dimensions. We obtain the Lagrangian that describes the lowest order coupling of the field to the four-dimensiona…
Green Functions, Sommerfeld Images, and Wormholes
Hassan Alshal
Electrostatic Green functions for grounded equipotential circular and elliptical rings, and grounded hyperspheres in n-dimension electrostatics, are constructed using Sommerfeld's…
Massless Charged Particles, Naked Singularity, and Generalized Uncertainty Principle in Reissner-Nordström-de Sitter-like spacetime
Elias C. Vagenas, Ahmed Farag Ali, Hassan Alshal
Motivated by the endeavors of Li Xiang and You-Gen Shen on naked singularities, we investigate the validity of the cosmic censorship conjecture in the context of generalized uncert…
Linear and Quadratic GUP, Liouville Theorem, Cosmological Constant, and Brick Wall Entropy
Elias C. Vagenas, Ahmed Farag Ali, Mohammed Hemeda +1
Motivated by the works on Equivalence Principle in the context of linear Generalized Uncertainty Principle and, independently, in the context of quadratic Generalized Uncertainty P…
Proton Decay and the Quantum Structure of Spacetime
Abeer Al-Modlej, Salwa Alsaleh, Hassan Alshal +1
Virtual black holes in noncommutative spacetime are investigated using coordinate coherent state formalism such that the event horizon of black hole is manipulated by smearing it w…
