  • Fading Hawking Radiation 
    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 ...
  • First-Order Intertwining Operators with Position Dependent Mass and η-Weak-Pseudo-Hermiticity Generators 
    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 ...

    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 ...
  • Gravitational Lensing Effect on the Hawking Radiation of Dyonic Black Holes 
    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 ...

    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 ...

    Mirekhtiary, Seyedeh Fatemeh; Sakallı, İzzet (Communications in Theoretical Physics, Institute of Physics (IOP) Publishing, 2014)
    In this paper, we consider the relativistic Hamilton-Jacobi (HJ) equation and study the Hawking radiation (HR) of scalar particles from uncharged Grumiller black hole (GBH) which is affordable for testing in astrophysics. ...

    Paşaoğlu, Hale; Sakallı, İzzet (International Journal of Theoretical Physics, Springer, 2009)
    Using the Damour-Ruffini-Sannan, the Parikh-Wilczek and the thin film brick-wall models, we investigate the Hawking radiation of uncharged massive particles from 4-dimensional linear dilaton black holes, which are the ...

    Sakallı, İzzet; Övgün, Ali (Springer, 2016-08-20)
    The Hawking radiation is considered as a quantum tunneling process, which can be studied in the framework of the Hamilton–Jacobi method. In this study, we present the wave equation for a mass generating massive and charged ...
