  • Quantization of Higher Dimensional Linear Dilaton Black Hole Area/Entropy From Quasinormal Modes 
    Sakallı, İzzet (International Journal of Modern Physics A, World Scientific Publishing, 2013)
    The quantum spectra of area and entropy of higher dimensional linear dilaton black holes in various theories via the quasinormal modes method are studied. It is shown that quasinormal modes of these black holes can reveal ...
  • Quantization of rotating linear dilaton black holes 
    Sakallı, İzzet (European Physical Journal C, Springer, 2015)
    In this paper, we focus on the quantization of 4−dimensional rotating linear dilaton black hole (RLDBH) spacetime describing an action, which emerges in the Einstein-Maxwell-Dilaton-Axion (EMDA) theory. RLDBH spacetime has ...

    The formation of a naked singularity in f(R) global monopole spacetime is considered in view of quantum mechanics. Quantum test fields obeying the Klein−Gordon, Dirac and Maxwell equations are used to probe the classical ...
  • 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 ...

    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 ...
  • Quantum tunneling of massive spin-1 particles from non-stationary metrics 
    Sakallı, İzzet; Övgün, Ali (General Relativity and Gravitation, Springer, 2015-11-15)
    We focus on the HR of massive vector (spin-1) particles tunneling from Schwarzschild BH expressed in the Kruskal–Szekeres and dynamic Lemaitre coordinates. Using the Proca equation together with the Hamilton–Jacobi and ...

    Mustafa, Omar; Mazharimousavi, Habib S. (IOP Publishing, 2010-11)
    A quasi-free quantum particle endowed with a Heaviside position-dependent mass jump is observed to experience scattering effects manifested by its by-product introduction of the derivative of the Dirac delta point dipole ...

    Sakallı, İzzet (Modern Physics Letters A, World Scientific Publishing, 2013)
    In this study, we employ the scalar perturbations of the charged dilaton black hole (CDBH) found by Chan, Horne and Mann (CHM), and described with an action which emerges in the low-energy limit of the string theory. A ...
  • 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 ...

    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 ...
