Unitary symmetries in wormhole geometry and its thermodynamics
Ahmed Farag Ali, Emmanuel Moulay, Kimet Jusufi +1
From a geometric point of view, we show that the unitary symmetries and stem fundamentally from Schwarzschild and Reissner-Nordström wormhole geometry through spacet…
Einstein's equations and the pseudo-entropy of pseudo-Riemannian information manifolds
Hassan Alshal
Motivated by the corrected form of the entropy-area law, and with the help of von Neumann entropy of quantum matter, we construct an emergent spacetime by the virtue of the geometr…
Newtonian Gravity on an N-Sphere
T Curtright, H Alshal
We consider some elementary features of Newtonian gravity, or electrostatics, as defined on an N-sphere. In particular, we present and discuss "the shell theorem" for this system.
Gravitational Observations and LQGUP
Mohammed Hemeda, Hassan Alshal, Ahmed Farag Ali +1
Motivated by recent works, we employ the bounds on the dimensionless quantum-gravity parameter obtained from six gravitational tests in order to obtain bounds on the dimensionless…
Dual Fields of Massive/Massless Gravitons in IR/UV Completions
Ashkbiz Danehkar, Hassan Alshal, Thomas L. Curtright
In the holographic picture, the Brout-Englert-Higgs (BEH) mechanism in d-dimensional Yang-Mills theories is conjectured to provide a Higgs-like mechanism for gravity in d+1 dimensi…
On Enceladian Fields
T. S. Van Kortryk, T. L. Curtright, H. Alshal
We fantasize about an alternative history for theories of electromagnetism and gravitation.
Massless Charged Particles Tunneling Radiation from a RN-dS Horizon and the Linear and Quadratic GUP
Elias C. Vagenas, Ahmed Farag Ali, Mohammed Hemeda +1
In this paper, we investigate the massless Reissner-Nordstrom de Sitter metric in the context of minimal length scenarios. We prove not only the confinement of the energy density o…
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…
GUP and the no-cloning theorem
Elias C. Vagenas, Ahmed Farag Ali, Hassan Alshal
Motivated by a recent work by Yongwan Gim, Hwajin Um, and Wontae Kim, we investigate the validity of the no-cloning theorem in the context of generalized uncertainty principle. In…
Image Charges Re-Imagined
H Alshal, T Curtright, S Subedi
We discuss the grounded, equipotential ellipse in two-dimensional electrostatics to illustrate different ways of extending the domain of the potential and placing image charges suc…
Grounded Hyperspheres as Squashed Wormholes
H Alshal, T Curtright
We compute exterior Green functions for equipotential, grounded hyperspheres in N-dimensional electrostatics by squashing Riemannian wormholes, where an image charge is placed in t…
The Conducting Ring Viewed as a Wormhole
T Curtright, H Alshal, P Baral +5
We compute the exterior Green function for a grounded equi-potential circular ring in two-dimensional electrostatics by treating the system geometrically as a "squashed wormhole" w…
A Galileon Primer
Thomas L. Curtright, David B. Fairlie, Hassan Alshal
Elementary features of galileon models are discussed at an introductory level. Following a simple example, a general formalism leading to a hierarchy of field equations and Lagrang…
