  • Sakallı, İzzet; Halilsoy, Mustafa; Paşaoğlu, Hale (Astrophysics and Space Science, Springer, 2012)
    In this study, we explore a particular type Hawking radiation which ends with zero temperature and entropy. The appropriate black holes for this purpose are the linear dilaton black holes. In addition to the black hole ...
  • Mustafa, Omar; Mazharimousavi, Seyed Habib (SPRINGER/PLENUM PUBLISHERS, 2008-02)
    A Hermitian and an anti-Hermitian first-order intertwining operators are introduced and a class of η-weak-pseudo-Hermitian position-dependent mass (PDM) Hamiltonians are constructed. A corresponding reference-target ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa (Physical Review D, American Physical Society (APS), 2014)
    We reconsider the generalized flare-out conditions in static wormhole throats given by Hochberg and Visser. We show that due to the presence of matter sources on the throat, these conditions are not applicable to the ...
  • Mustafa, Omar; Mazharimousavi, Habib S. (Natl Acad Sci Ukraine, 2010)
    The kinetic energy operator with position-dependent-mass in plane polar coordinates is obtained. The separability of the corresponding Schrodinger equation is discussed. A hypothetical toy model is reported and two exactly ...
  • Mazharimousavi, S. Habib; Gürtuğ, Özay; Halilsoy, Mustafa (International Journal of Modern Physics D, World Scientific Publishing, 2009)
    Generalization of a known theorem to generate static, spherically symmetric black-hole solutions in higher dimensional Lovelock gravity is presented. Particular limits, such as Gauss-Bonnet (GB) and/or Einstein-Hilbert ...
  • Benghrian, Asma Ali Abdulsalam (Eastern Mediterranean University EMU, 2017-07)
    We give a full investigation and assessment on the general spherically symmetric time-like thin shells in general relativity. In this main stream, we give the details of the Israel junction conditions which are used for ...
  • Hamo, Alan Hameed Hussein (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-08)
    In this thesis, we investigate the geodesics of the 4-dimensional (4D) linear dilaton black hole (LDBH), which is an exact solution to the Einstein-Maxwell-Dilaton (EMD) theory. These spacetimes have non-asymptotically ...
  • Sharon, Jo-Kim Dauda Tok (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2015-02)
    ABSTRACT: On a Cosmic Landscape, the metric structure vested with two orthogonal space-like Killing vectors; a class of solutions of the Einstein-Maxwell’s field equations, is spotlighted from the global structural viewpoints ...
  • Parsa, Marzieh (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-07)
    ABSTRACT: In this thesis we study one of the most interesting aspects of the Einstein’s theory of gravity which can be examined practically by astronomers. In this natural phenomena, when a beam of light passes nearby a ...
  • Sakllı, İzzet; Övgün, Ali; Mirekhtiary, S.F. (World Scientific Publishing, 2014-06-24)
    In this paper, we analyze the Hawking radiation (HR) of a non-asymptotically flat (NAF) dyonic black hole (dBH) in four-dimensional (4D) Einstein–Maxwell–Dilaton (EMD) gravity by using one of the semiclassical approaches ...
  • Sakalli, İzzet; Övgün, Ali (Astrophysics and Space Science, Springer, 2015-08-19)
    Recent research shows that Hawking radiation (HR) is also possible around the trapping horizon of a wormhole. In this article, we show that the HR of gravitino (spin-3/2 ) particles from the traversable Lorentzian wormholes ...

    In this thesis, we analytically study the scalar perturbation of non-asymptotically flat 2+1 dimensional charged dilaton black holes. In particular, we show that radial wave equation is solved in terms of the hypergeometric ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa (Foundations of Physics, Springer, 2012)
    Within the context of Born-Infeld (BI) nonlinear electrodynamics (NED) we revisit the non-relativistic, spinless H-atom. The pair potential computed from the Born-Infeld equations is approximated by the Morse type potential ...
  • Sakallı, İzzet; Övgün, Ali; Kimet, Jusufi (Springer, 2016-09-13)
    Recent studies (Steinhauer in Nat. Phys. 10:864, 2014, Phys. Rev. D 92:024043, 2015) provide compelling evidences that Hawking radiation could be experimentally proven by using an analogue black hole. In this paper, taking ...
