  • Quantum singularities in a model of f(R) Gravity 
    Tahamtan, Tayabeh; Gürtuğ, Özay (European Physical Journal C: Particles and Fields, Springer, 2012)
    The formation of a naked singularity in a model of f(R) gravity having as source a linear electromagnetic field is considered in view of quantum mechanics. Quantum test fields obeying the Klein-Gordon, Dirac and Maxwell ...
  • Reflection of electromagnetic waves from mixtures of plane gravitational and scalar waves 
    Gürtuğ, Özay; Halilsoy, Mustafa; Ünver, Özlem (Physical Review D,, 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. ...
  • 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. ...
  • Restricted Class of Colliding Einstein-Yang-Mills Plane Waves 
    Gürtuğ, Özay; Halilsoy, Mustafa (International Journal of Modern Physics A, World Scientific Publishing, 2009)
    By gauging an Abelian electromagnetic (em) solution through a non-Abelian transformation and in accordance with a theorem proved long time ago, we construct a simple class of colliding Einstein-Yang-Mills (EYM) plane waves. ...
  • Rindler modified Schwarzschild geodesics 
    Halilsoy, Mustafa; Gürtuğ, Özay; Mazharimousavi, S. Habib (General Relativity and Gravitation, Springer, 2013)
    The mysterious attractive constant radial force acted in the past on Pioneer spacecrafts - the so-called Pioneer anomaly - is considered within the context of Rindler acceleration. As an idea this is tempting since it is ...
  • Search For Gravitational Waves Through the Electromagnetic Faraday Rotation 
    Halilsoy, Mustafa; Gürtuğ, Özay (Physical Review D, American Physical Society (APS), 2007)
    A method is given which renders indirect detection of strong gravitational waves possible. This is based on the reflection (collision) of a linearly polarized electromagnetic shock wave from (with) a cross polarized impulsive ...

  • Theorem to generate Einstein-Non Linear Maxwell Fields 
    Mazharimousavi, S. Habib; Gürtuğ, Özay; Halilsoy, Mustafa (Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 2010)
    We present a theorem in d-dimensional static, spherically symmetric spacetime in generic Lovelock gravity coupled with a non-linear electrodynamic source to generate solutions. The theorem states that irrespective of the ...
