  • The Runge-Kutta method in geometric multiplicative calculus 
    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 ...
  • Scalar Clouds and Quasinormal Modes 
    Tokgöz, Gülnihal (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2019-01)
    In this thesis, Maggiore’s method (MM), which evaluates the transition frequency that appears in the adiabatic invariant from the highly damped quasinormal mode frequencies (QNMFs), is used to investigate the entropy and ...
  • Scalar Plane Waves in General Relativity 
    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.
  • A scan of f(R) models admitting Rindler type acceleration 
    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 ...
  • Schrödinger Equation with Noninteger Dimensions 
    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 ...
  • Screening of the Reissner–Nordström charge by a thin-shell of dust matter 
    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 ...
  • Search For Gravitational Waves Through the Electromagnetic Faraday Rotation 
    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 ...
  • Seismic AVO attributes and rock Physics in hydrocarbon exploration 
    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 ...
  • Self-adjoint Extensions of the Operators and Their Applications in Physics 
    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. ...
  • Self-Focusing of Laser Beams in Analogy of Gravitational Waves 
    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 ...
  • Separable Wave Equation in the Space of Colliding Waves 
    Mustafa, Halilsoy (Physics Letters A, Elsevier, 1990)
    We show that the massive wave equation is separable in two different space—times, both arising from the collision of the cross polarized plane gravitational waves. Exact solutions can be expressed in terms of infinite series.
  • Shadow Cast of the Schwarzschild-like Black Holes 
    Babayeva, Flora (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2021-12)
    The Event Horizon Telescope has recently seen the edge of a black hole. This fruitful outcome reveals a fine structure near the black hole horizon. The photon ring and shadow have been clearly observed which provides ...
  • Shifted 1/N expansion for the Klein-Gordon equation with vector and scalar potentials 
    Mustafa, Omar; Sever, Ramazan (American Physical Society (APS), 1990)
    The shifted 1/N expansion method has been extended to solve the Klein-Gordon equation with both scalar and vector potentials. The calculations are carried out to the third-order correction in the energy series. The analytical ...
