  • 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. ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayebeh (Physics Letters A, Elsevier, 2012)
    It is well-known that unlike its chargeless version the charged Banados-Teitelboim-Zanelli (BTZ) black hole solution in 2+1- dimensional spacetime is singular. We construct a charged, regular extension of the BTZ black ...
  • Sakallı, İzzet; Tokgöz, Gülnihal (Hindawi Publishing Corporation, 2015)
    Maggiore’s method (MM), which evaluates the transition frequency that appears in the adiabatic invariant from the highly damped quasinormal mode (QNM) frequencies, is used to investigate the entropy/area spectra of the ...
  • Gürtuğ, Özay; Halilsoy, Mustafa (International Journal of Modern Physics A, World Scientific Publishing, 2009)
    By gauging an Abelian electromagnetic (em) solution through a non-Abelian transformation and in accordance with a theorem proved long time ago, we construct a simple class of colliding Einstein-Yang-Mills (EYM) plane waves. ...
  • Halilsoy, Mustafa; Gürtuğ, Özay; Mazharimousavi, S. Habib (General Relativity and Gravitation, Springer, 2013)
    The mysterious attractive constant radial force acted in the past on Pioneer spacecrafts - the so-called Pioneer anomaly - is considered within the context of Rindler acceleration. As an idea this is tempting since it is ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa (Modern Physics Letters A, World Scientific Publishing, 2013)
    By choosing a fluid source in f(R) gravity, defined by f(R) = R-12aξ ln|R|, where a (Rindler acceleration) and ξ are both constants, the field equations correctly yield the Rindler acceleration term in the metric. We ...
  • Övgün, Ali (SpringerLink, 2016-11-08)
    We construct a rotating thin-shell wormhole using a Myers-Perry black hole in five dimensions, using the Darmois-Israel junction conditions. The stability of the wormhole is analyzed under perturbations. We find that exotic ...
  • Rıza, Mustafa; Aktöre, Hatice (Cambridge Univ Press, 2015)
    This paper illuminates the derivation, applicability, and efficiency of the multiplicative Runge Kutta method, derived in the framework of geometric multiplicative calculus. The removal of the restrictions of geometric ...
  • Halilsoy, Mustafa (Lettere Al Nuovo Cimento, Societa Italiana di Fisica, 1985)
    A more general class of scalar plane waves is presented in general relativity. It is shown that no matter how the scalar field is modified, space-time possesses an essential singularity.
  • Mazharimousavi, S. Habib; Kerachian, Morteza; Halilsoy, Mustafa (European Physical Journal C: Particles and Fields, Springer, 2014)
    As a manifestation of large distance effect Grumiller modified Schwarzschild metric with an extraneous term reminiscent of Rindler acceleration. Such a term has the potential to explain the observed flat rotation curves ...
  • Hssain, Ala Hamd (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-09)
    ABSTRACT: Exact solutions in quantum theory play crucial roles in the application areas of the theory. For instance knowing the exact eigenvalues and eigen-functions of the Hamiltonian of the Hydrogen atom helps the Chemists ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa (European Physical Journal C: Particles and Fields, Springer, 2015-07)
    A concentric charged thin-shell encircling a Reissner-Nordstr\"{o}m black hole screens the clectric / magnetic charge completely to match with an external Schwarzschild black hole. The negative mass thin-shell is shown to ...
  • Halilsoy, Mustafa; Gürtuğ, Özay (Physical Review D, American Physical Society (APS), 2007)
    A method is given which renders indirect detection of strong gravitational waves possible. This is based on the reflection (collision) of a linearly polarized electromagnetic shock wave from (with) a cross polarized impulsive ...
  • Jalali, Vajiheh (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-01)
    ABSTRACT: During past two decades amplitude variation with offset (AVO) is a known technique that has been used in direct hydrocarbon exploration and exploitation, which uses the amplitudes of pre-stack seismic data to ...
  • Emral, Kıymet (Eastern Mediterranean University (EMU), 2013)
    ABSTRACT: In this thesis, self-adjoint extensions of some of the operators used in quantum mechanics are studied. First, the necessary mathematical background namely, the vector spaces and Hilbert space are reviewed. ...
  • Eser, Aydıroğlu; Mustafa, Halilsoy (Physics Letters A, Elsevier, 1992)
    We consider an extended version of Takatsuji’s laser beam — in analogy with null geodesics in the space—time of interacting waves— which focuses itself in a non-linear medium. It is shown that weak“rotational” effects ...
