2+1 dimensional magnetically charged solutions in Einstein - Power - Maxwell theory

Mazharimousavi, S. Habib; Gürtuğ, Özay; Halilsoy, Mustafa; Ünver, Özlem (Physical Review D, Springer, 2011)

We obtain a class of magnetically charged solutions in 2+1 dimensional Einstein - Power - Maxwell theory. In the linear Maxwell limit, such horizonless solutions are known to exist. We show that in 3D geometry, black hole ...
Colliding wave solutions from five-dimensional black holes and black pp-branes

Halilsoy, Elif; Halilsoy, Mustafa; Ünver, Özlem (Journal of Mathematical Physics, American Institute of Physics (AIP), 2006)

e consider both the five-dimensional Myers-Perry and Reissner-Nordstrom black holes (BHs) and black pp -branes in (4+p)(4+p) -dimensions. By employing the isometry with the colliding plane waves (CPWs) we generate ...
Quantum singularities in (2+1) dimensional matter coupled black hole spacetimes

Ünver, Özlem; Gürtuğ, Özay (Physical Review D, American Physical Society (APS), 2010)

Quantum singularities considered in the 3D BTZ spacetime by Pitelli and Letelier (Phys. Rev. D77: 124030, 2008) is extended to charged BTZ and 3D Einstein-Maxwell-dilaton gravity spacetimes. The occurence of naked singularities ...
Quantum Singularities in (2+1) Dimensional Matter Coupled Black Hole Spacetimes

Ünver, Özlem (Eastern Mediterranean University (EMU), 2012)

ABSTRACT: Quantum singularities are considered in matter coupled 2+1 dimensional spacetimes in Einstein’s theory. The occurrence of naked singularities in the spacetimes both in linear and non-linear electrodynamics in ...
Reflection of electromagnetic waves from mixtures of plane gravitational and scalar waves

Gürtuğ, Özay; Halilsoy, Mustafa; Ünver, Özlem (American Physical Soc, 2006)

We consider colliding wave packets consisting of hybrid mixtures of electromagnetic, gravitational, and scalar waves. Irrespective of the scalar field, the electromagnetic wave still reflects from the gravitational wave. ...
