  • Övgün, Ali (Izmir Institute of Technology - İzmir Yüksek Teknoloji Enstitüsü, 2010)
    Thıs is my undergraduate thesis. So far I have worked on tunneling and its classi-cal, semi-classical and quantum description, then I looked some unsolved problems . Ihave learned about Hartman e ect , ...
  • Övgün, Ali (University of Southampton, 2011)
  • Eser, Muhittin Cenk (Eastern Mediterranean University (EMU), 2011)
    ABSTRACT: The tunneling time problem was a very popular problem at the end of the 20th century.In Quantum Mechanics only observables can be measured, i.e. these observables are real quantities. From mathematics it is well ...
  • Farahi, Atena (Eastern Mediterranean University (EMU), 2011)
    According to the Eric Verlinde’s arguments on the gravity, we study the entropic force of two spacetimes without and with dilaton field, which are the Schwarzschild black hole and the charged dilaton black hole respectively. ...
  • 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 ...
  • Ünver, Özlem (Eastern Mediterranean University (EMU), 2012)
    ABSTRACT: Quantum singularities are considered in matter coupled 2+1 dimensional spacetimes in Einstein’s theory. The occurrence of naked singularities in the spacetimes both in linear and non-linear electrodynamics in ...
  • Lajevardipour, Alireza (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2012-06)
  • Amirabi, Zahra (Eastern Mediterranean University (EMU), 2012-08)
    ABSTRACT: The concept of thin-shell wormholes has been considered in Einstein’s theory of gravity coupled with different matter sources likeMaxwell, Yang-Mills, Born-Infeld- Hoffman fields, generalized Chaplygin gas and ...
  • 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. ...
  • 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) ...
  • Alizadeh, Yashar (Eastern Mediterranean University (EMU), 2013)
    ABSTRACT: In the framework of the non-linear electrodynamics, we introduce a new Lagrangian with Maxwell limit which admits a regular electric field and electric potential at the origin. In static spherically symmetric ...
  • 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 ...
  • Saleh, Najm Abdola (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-06)
    ABSTRACT: In this thesis we study physics on the rotating Earth by studying the moving coordinate systems and rotating coordinate systems. First, we illustrate briefly some kind of translations like Galilean transformation ...
  • Roozbeh, Ashkan (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-07)
    ABSTRACT: The electromagnetic wave propagation in inhomogeneous media is studied. The wave equation in such a medium is obtained. By considering the permittivity as a positiondependent function (i.e, z-dependent) and the ...
  • Parsa, Marzieh (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-07)
    ABSTRACT: In this thesis we study one of the most interesting aspects of the Einstein’s theory of gravity which can be examined practically by astronomers. In this natural phenomena, when a beam of light passes nearby a ...
  • Kerachian, Morteza (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-07)
    ABSTRACT: We investigate the existence of Reissner-Nordström (RN) type black holes in f (R) gravity. Our emphasis is to derive, in the presence of electrostatic source, the necessary conditions which provide such static, ...
  • Al-Aakol, Ashwaq Eyad Kadhim (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-09)
    ABSTRACT: In this thesis we study a quantum particle with position dependent mass (PDM). We start from the general form of the kinetic energy operator in which the physical requirements are considered and then we show that ...
  • Shakibaei, Ali Akbar (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-01)
    ABSTRACT: Reflectance spectroscopy is a method to noninvasively quantitate the scattering and absorption properties of a turbid medium like tissue. The absorption and scattering properties can be used in diagnosis of ...
  • 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 ...
  • 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 ...
