  • 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 ...
  • 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 ...
  • Adamu, Suleiman Bashir (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-06)
    ABSTRACT: In this thesis, we study the role of boundary conditions via -symmetric quantum mechanics. Where denotes parity operator and denotes time reversal operator. We present the boundary conditions so that the -symmetry ...
  • Mustafa, Omar; Mazharimousavi, Seyed Habib (Elsevier, 2006-10-23)
    We consider a free particle, V (r) = 0, with a position-dependent mass m(r) = 1/(1 + ς2r2)2 in the d-dimensional Schrödinger equation. The effective potential turns out to be a generalized Pöschl–Teller potential that ...
  • Gürtuğ, Özay; Mazharimousavi, S. Habib; Halilsoy, Mustafa (Advances in High Energy Physics, Hindawi Publishing Corporation, 2015)
    The formation of naked singularities in 2+1-dimensional power-law spacetimes in linear Einstein-Maxwell and Einstein-scalar theories sourced by azimuthally symmetric electric field and a self-interacting real scalar field, ...
  • Gürtuğ, Özay; Halilsoy, Mustafa; Mazharimousavi, S. Habib (Journal of High Energy Physics, Springer, 2014)
    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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Övgün, Ali (Izmir Institute of Technology - İzmir Yüksek Teknoloji Enstitüsü, 2010)
    Thıs is my undergraduate thesis. So far I have worked on tunneling and its classi-cal, semi-classical and quantum description, then I looked some unsolved problems . Ihave learned about Hartman e ect , ...
  • 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 ...
  • 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 ...
  • Saty, Majeed J. Saleem (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2015-01)
    ABSTRACT: By exploring the Position-dependent mass Von Roos Hamiltonian under cylindrical coordinates settings, we discuss the separation of variables of Schrödinger equation. Two radial masses of a coulomb-type and a ...
  • 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 ...
  • 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 ...
  • 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. ...
