  • Compton Scattering 
    Övgün, Ali (University of Southampton, 2011)
  • Constant curvature f(R) gravity minimally coupled with Yang-Mills field 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayebeh (European Physical Journal C, Springer, 2011)
    We consider the particular class of f(R) gravities minimally coupled with Yang - Mills (YM) field in which the Ricci scalar =R_{0}= constant in all dimensions d\geq4. Even in this restricted class the spacetime has unlimited ...
  • Cosmic Strings Coupled With a Massless Scalar Field 
    Gürtuğ, Özay; Sakallı, İzzet (International Journal of Theoretical Physics, Springer, 2003)
    A scalar field generalization of Xanthopoulos's cylindrically symmetric solutions of the vacuum Einstein equation is obtained. The obtained solution preserves the properties of the Xanthopoulos solution, which are regular ...
  • Cosmology with Variable Physical Constants 
    Joseph, Gabriel Wirdzelii (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2020)
    The speed of light is taken to be a constant in a vacuum. This forms the basic tool for the principle of General Covariance, which asserts that, all laws of Physics should take the same form in all frames of reference. ...
  • Counterrotational effects on stability of 2+1-dimensional thin-shell wormholes 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (The European Physical Journal C, Springer, 2014)
    The role of angular momentum in a 2+1-dimensional rotating thin-shell wormhole (TSW) is considered. Particular emphasis is made on stability when the shells (rings) are counterrotating. We find that counter-rotating halves ...
  • Cross-Polarized Cylindrical Gravitational Waves of Einstein and Rosen 
    Halilsoy, Mustafa (Nuovo Cimento B, Springer, 1988)
    Using Einstein-Rosen's linearly polarized waves as the seed solution, we derive an interesting solution for the Einstein's equations that describes the evolution of such waves with the second polarization.
  • The Dark Matter 
    Övgün, Ali (2016-01-07)
  • Dark Matter; Modification of f (R) or Wimps Miracle 
    Övgün, Ali (Eastern Mediterranean University (EMU), 2013)
    ABSTRACT: The identity of dark matter is one of the key outstanding problems in both particle and astrophysics. In this thesis, I review some candidates of dark matter, especially WIMPs (weakly interacting massive particles) ...
  • Dark Matter; Modification of F(R) or Wimps Miracle 
    Övgün, Ali (2016-01-08)
  • Dark side of the cosmos 
    Övgün, Ali (2016-01-07)
  • d-dimensional generalization of the point canonical transformation for a quantum particle with position-dependent mass 
    Mustafa, Omar; Mazharimousavi, Seyed Habib (IOP Science, 2006-08-02)
    The d-dimensional generalization of the point canonical transformation for a quantum particle endowed with a position-dependent mass in the Schr¨odinger equation is described. Illustrative examples including the harmonic ...
  • d-dimensional non-asymptotically flat thin-shell wormholes in Einstein-Yang-Mills-Dilaton gravity 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Amirabi, Zahra (Physics Letters A, Elsevier, 2011)
    Thin-shell wormholes in Einstein-Yang-Mills-dilaton (EYMD) gravity are considered. We show that a non-asymptotically flat (NAF) black hole solution of the d-dimensional EYMD theory provides stable thin-shell wormholes which ...
  • d-dimensional Position Dependent Mass, Quasi-Free Quantum Particle 
    Taha, Khozer Abdalrahim (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2015-01)
    ABSTRACT: This thesis deals with the applications of PDM in one and d-dimensions. In the one-dimensional case the classical as well as the quantum mechanical approach are discussed, and the position dependent mass formalism ...
  • Deformed Schioberg-Type Potential and Rotational-Vibrational Spectra for Some Diatomic Molecules 
    Hama, Fakhir Omer (Eastern Mediterranean University EMU, 2017-01)
    This thesis aims to discuss the deformed Schiӧberg-type potential for some diatomic molecules. The s conditions are used to show a common diatomic molecular potential model. It also aims to employ the radial spherically ...
  • Dilatonic Entropic Force 
    Sakallı, İzzet (International Journal of Theoretical Physics, Springer, 2011)
    We show in detail that the entropic force of the static spherically symmetric spacetimes with unusual asymptotics can be calculated through the Verlinde's arguments. We introduce three different holographic screen candidates, ...
  • Dilatonic interpolation between Reissner-Nordstrom and Bertotti-Robinson spacetimes with physical consequences 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Sakallı, İzzet; Gürtuğ, Özay (Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 2010)
    We give a general class of static, spherically symmetric, non-asymptotically flat and asymptotically non-(anti) de Sitter black hole solutions in Einstein-Maxwell-Dilaton (EMD) theory of gravity in 4-dimensions. In this ...
  • Dirac and Klein–Gordon particles in complex Coulombic fields: a similarity transformation 
    Mustafa, Omar (IOP Publishing, 2003)
    The observation that the existence of the amazing reality and discreteness of the spectrum need not necessarily be attributed to the Hermiticity of the Hamiltonian is re-emphasized in the context of the non-Hermitian Dirac ...
  • Distinct Family of Colliding Waves in General Relativity 
    Halilsoy, Mustafa (Physical Review D, American Physical Society (APS), 1988)
    We present a new family of exact solutions for the Einstein equations that describes colliding gravitational shock waves with cross polarization. In the limit of single polarization it reduces to a family that, up to a ...
  • Domain-Walls in Einstein-Gauss-Bonnet Bulk 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (Physical Review D, American Physical Society (APS), 2010)
    We investigate the dynamics of a d-dimensional domain wall (DW) in a d+1-dimensional Einstein-Gauss-Bonnet (EGB) bulk. Exact effective potential induced by the Gauss-Bonnet (GB) term on the wall is derived. In the absence ...
  • Double-bounce domain-wall in Einstein-Yang-Mills-Scalar black holes 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayabeh (European Physical Journal C, Springer, 2013)
    We find Einstein-Yang-Mills (EYM) black hole solutions endowed with massless scalar hair in the presence of a potential V(ϕ) as function of the scalar field ϕ. Choosing V(ϕ)=constant (or zero) sets the scalar field to ...
