  • Övgün, Ali (Springer, 2017-02-16)
    Despite impressive phenomenological success, cosmological models are incomplete without an understanding of what happened at the big bang singularity. Maxwell electrodynamics, considered as a source of the classical Einstein ...
  • Paşaoğlu, Hale (Eastern Mediterranean University (EMU), 2012)
    ABSTRACT: Using the Damour-Ruffini-Sannan and the Parikh-Wilczek methods, we analyze the Hawking radiation of uncharged massive particles for linear dilaton black holes with N ≥ 4 dimensions. Contrary to the many studies ...
  • Halilsoy, Mustafa (Nuovo Cimento B, Societa Italiana di Fisica, 1987)
    We study the interacting electromagnetic shock waves with nonconstant profiles in general relativity. It is shown that by modifying the metric functions of the Bell-Szekeres solution, such solutions can be obtained.
  • Metin, Gürses; Halilsoy, Mustafa (Lettere Al Nuovo Cimento, Italian Physical Society, 1982)
    We present a solution of the Einstein-Maxwell field equations describing the collision of superposed electromagnetic shock plane waves
  • Halilsoy, Mustafa (General Relativity and Gravitation, Springer, 1993)
    The two well-known solutions of general relativity, the Schwarzschild and the Bertotti-Robinson solutions, are shown to be described by a common metric. In a particular coordinate system we show the connection between ...
  • Sulaiman, Rafea Ismael (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-01)
    ABSTRACT: In this study we give a brief introduction to the basic differential equation for zero spin relativistic particle which is called Klein-Gordon equation. Klein-Gordon equation, then, is presented in 1+1-dimensions ...

  • Mazharimousavi, S. Habib; Halilsoy, Mustafa (Physics Letters B, Elsevier, 2009)
    We consider the standard Yang-Mills (YM) invariant raised to the power q, i.e., (F(a)μνF(a)μν)q as the source of our geometry and investigate the possible black hole solutions. How does this parameter q modify the black ...
  • Mustafa, Omar; Odeh, Maen (INST PHYSICS ACAD SCI CZECH REPUBLIC, Springer (Online Publishing), 2002)
    Magnetic fingerprints on the spectra of an interacting electron with a negatively charged ion in a parabolic quantum dot (QD), and of two interacting electrons in such a dot, are investigated via a pseudoperturbative ...
  • Övgün, Ali; Jusufi, Kimet (Springer, 2016-05-30)
    In this paper, we investigate the tunneling process of charged massive bosons W± (spin-1 particles) from noncommutative charged black holes such as charged RN black holes and charged BTZ black holes. By applying the WKB ...
  • Halilsoy, Mustafa (Physics Letters A, Elsevier, 1981)
    We present another method of generating new solutions from old ones in general relativity. In particular we apply the method to some well-known classes of gravitational fields.
  • Halilsoy, Mustafa; Al-Badawi, A (Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 1995)
    We present the metric of a Schwarzschild (S) black hole coupled to an external, stationary electromagnetic Bertotti–Robinson (BR) solution. This metric generalizes a previous metric that served to unify the S and BR ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa; Amirabi, Zahra (European Physical Journal C: Particles and Fields, Springer, 2014)
    We construct thin shell wormholes in the magnetic Melvin universe. It is shown that in order to make a TSW in the Melvin spacetime the radius of the throat can not be larger than 2B0 in which B0 is the magnetic field ...
  • Halilsoy, Mustafa; Gürtuğ, Özay; Mazharimousavi, S. Habib (Astroparticle Physics, Elsevier, 2015)
    The model proposed originally by Mannheim and Kazanas for fitting the shapes of galactic rotation curves has recently been considered by Grumiller to describe gravity of a central object at large distances. Herein we employ ...
  • Halilsoy, Mustafa; Al-Badawi, A. (Nuovo Cimento B, Springer, 1998)
  • Rıza, Mustafa; Özyapıcı, Ali; Mısırlı, Emine (Brown University, 2009)
    Based on multiplicative calculus, the finite difference schemes for the numerical solution of multiplicative differential equations and Volterra differential equations are presented. Sample problems were solved using these ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa; Amirabi, Zahra (General Relativity and Gravitation, Springer, 2009)
    We find large classes of non-asymptotically flat Einstein-Yang-Mills-Dilaton (EYMD) and Einstein-Yang-Mills-Born-Infeld-Dilaton (EYMBID) black holes in N-dimensional spherically symmetric spacetime expressed in terms of ...
  • Mustafa, Omar (IOP Publishing, 2015)
    We suggest a new deformed Schioberg-type potential for diatomic molecules. We show that it is equivalent to Tietz-Hua oscillator potential. We discuss how to relate our deformed Schi\"oberg potential to Morse, to Deng-Fan ...

    We introduce a class of solutions in 2+1−dimensional Einstein-Power-Maxwell theory for circularly symmetric electric field. The electromagnetic field is considered with an angular component given by $% F_{\mu \nu ...
  • Tahamtan, Tayebeh (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-06)
    ABSTRACT: Some new exact solutions in a model of f (R) gravity are obtained. Three kinds of matter fields have been used to obtain exact analytic solutions. In the first solution, the Yang-Mills fields are incorporated ...
