  • Radial power-law position-dependent mass: Cylindrical coordinates, separability and spectral signatures 
    Mustafa, Omar (IOP Publishing, 2011)
    We discuss the separability of the position-dependent-mass (PDM) Hamiltonian in cylindrical coordinates in the framework of a radial power-law PDM. We consider two particular radial mass settings: a harmonic oscillator ...
  • A Realizable Quantum Three-Pass Protocol Authentication Based on Hill-Cipher Algorithm 
    Abdullah, Alharith A.; Khalaf, Rifaat; Rıza, Mustafa (Hindawi Publishing Corporation, 2015)
    A realizable quantum three-pass protocol authentication based on Hill-cipher algorithm is presented by encoded and decoded plaintext using classical Hill-cipher algorithm. It is shown that the encoded message transferred ...
  • Real spectra for non-Hermitian Dirac equation in 1+1 dimensions with a most general coupling 
    Mustafa, Omar (Elsevier, 2009)
    The most general combination of couplings of fermions with external potentials in 1+1 dimensions, must include vector, scalar and pseudoscalar potentials. We consider such a mixing of potentials in a PT-symmetric ...
  • 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. ...
  • Regular charged black hole construction in 2+1 -dimensions 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayebeh (Physics Letters A, Elsevier, 2012)
    It is well-known that unlike its chargeless version the charged Banados-Teitelboim-Zanelli (BTZ) black hole solution in 2+1- dimensional spacetime is singular. We construct a charged, regular extension of the BTZ black ...
  • Resonance Spectra of Caged Stringy Black Hole and Its Spectroscopy 
    Sakallı, İzzet; Tokgöz, Gülnihal (Hindawi Publishing Corporation, 2015)
    Maggiore’s method (MM), which evaluates the transition frequency that appears in the adiabatic invariant from the highly damped quasinormal mode (QNM) frequencies, is used to investigate the entropy/area spectra of the ...
  • 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 ...
  • Rindler Type Acceleration in f(R) Gravity 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (Modern Physics Letters A, World Scientific Publishing, 2013)
    By choosing a fluid source in f(R) gravity, defined by f(R) = R-12aξ ln|R|, where a (Rindler acceleration) and ξ are both constants, the field equations correctly yield the Rindler acceleration term in the metric. We ...
  • Rotating Thin-Shell Wormhole 
    Övgün, Ali (SpringerLink, 2016-11-08)
    We construct a rotating thin-shell wormhole using a Myers-Perry black hole in five dimensions, using the Darmois-Israel junction conditions. The stability of the wormhole is analyzed under perturbations. We find that exotic ...
  • The Runge-Kutta method in geometric multiplicative calculus 
    Rıza, Mustafa; Aktöre, Hatice (Cambridge Univ Press, 2015)
    This paper illuminates the derivation, applicability, and efficiency of the multiplicative Runge Kutta method, derived in the framework of geometric multiplicative calculus. The removal of the restrictions of geometric ...
  • Scalar Plane Waves in General Relativity 
    Halilsoy, Mustafa (Lettere Al Nuovo Cimento, Societa Italiana di Fisica, 1985)
    A more general class of scalar plane waves is presented in general relativity. It is shown that no matter how the scalar field is modified, space-time possesses an essential singularity.
  • A scan of f(R) models admitting Rindler type acceleration 
    Mazharimousavi, S. Habib; Kerachian, Morteza; Halilsoy, Mustafa (European Physical Journal C: Particles and Fields, Springer, 2014)
    As a manifestation of large distance effect Grumiller modified Schwarzschild metric with an extraneous term reminiscent of Rindler acceleration. Such a term has the potential to explain the observed flat rotation curves ...
  • Screening of the Reissner–Nordström charge by a thin-shell of dust matter 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (European Physical Journal C: Particles and Fields, Springer, 2015-07)
    A concentric charged thin-shell encircling a Reissner-Nordstr\"{o}m black hole screens the clectric / magnetic charge completely to match with an external Schwarzschild black hole. The negative mass thin-shell is shown to ...
  • 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 ...
