Charged Axially Symmetric Exponential Metric: Exact Solutions to the Einstein-Maxwell Equations
S. Habib Mazharimousavi
We construct and analyze charged and magnetized extensions of the axially symmetric exponential metric, that is known as the Curzon-Chazy spacetime (CCS) within the Weyl class. Wor…
Physical properties of charged black holes from the nonlinear electrodynamics model based on electric potential regularization
S. Habib Mazharimousavi
We investigate static, spherically symmetric black hole solutions arising from Einstein gravity minimally coupled to a nonlinear electrodynamics (NED) model constructed from a regu…
Stability of neutral and charged Dyson shells around Reissner-Nordstrom compact objects
S. Habib Mazharimousavi
In this Letter, we show that, in contrast to Dyson shells surrounding uncharged compact objects, which are generally unstable, a neutral Dyson shell enclosing a charged compact obj…
Topological Quantum Gravity through Harmonic S Maps
M. Halilsoy, S. Habib Mazharimousavi
By virtue of harmonic maps on two-dimensional spheres (S), a topological quantization in spacetime is proposed. The discrete character of all physical quantities follows natu…
Axially Symmetric Exponential Metric
S. Habib Mazharimousavi
We revisit the Yilmaz Exponential Metric (YEM), which was recently shown to describe a traversable wormhole, and construct an axially symmetric generalization strictly within the f…
Charged quantum Oppenheimer-Snyder model
S. Habib Mazharimousavi
In the framework of loop quantum cosmology, particularly within the quantum Oppenheimer-Snyder model, the semiclassical Ashtekar-Pawlowski-Singh (APS) metric is associated with a s…
