  • A singular position-dependent mass particle in an infinite potential well 
    Mustafa, Omar; Mazharimousavi, Habib S. (Elsevier B.V, 2009)
    An unusual singular position-dependent-mass particle in an infinite potential well is considered. The corresponding Hamiltonian is mapped through a point-canonical-transformation and an explicit correspondence between the ...

    Cellatoğlu, Nemika (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2016)
    Solar energy and biomass are two attractive renewable energy resources which gained special interest in recent years. However, problems like storage are preventing efficient and cheap utilization of solar energy and biomass. ...

    Mazharimousavi, S. Habib; Halilsoy, Mustafa (Physics Letters B, Elsevier, 2010)
    The hierarchies of both Lovelock gravity and power-Yang-Mills field are combined through gravity in a single theory. In static, spherically symmetric ansatz exact particular integrals are obtained in all higher dimensions. ...
  • Solution of Dirac equation in the near horizon geometry of an extreme Kerr black hole 
    Sakalli, Izzet; Halilsoy, Mustafa (Physical Review -Series d-, American Physical Society (APS), 2004)
    Dirac equation is solved in the near horizon limit geometry of an extreme Kerr black hole. We decouple equations first as usual, into an axial and angular part. The axial equation turns out to be independent of the mass ...

    Al-Badawi, Ahmad; Sakallı, İzzet (Journal of Mathematical Physics, American Institute of Physics (AIP), 2008)
    The Dirac equation is solved in the rotating Bertotti-Robinson spacetime. The set of equations representing the Dirac equation in the Newman-Penrose formalism is decoupled into an axial and angular part. The axial equation, ...
  • Solutions for f(R) gravity coupled with electromagnetic field 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayebeh (European Physical Journal C, Springer, 2012)
    In the presence of external, linear / nonlinear electromagnetic fields we integrate f(R) \sim R+2{\alpha}\surd(R+const.) gravity equations. In contrast to their Einsteinian cousins the obtained black holes are non-asymptotically ...
  • Specific dynamics for the Domain-Walls in Einstein-Maxwell-Dilaton theory 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 2012)
    We consider Einstein-Maxwell-Dilaton (EMD) Lagrangian supplemented by double Liouville potentials to enrich our system and investigate the resulting dynamics. The general solution provides us alternative structures induced ...
  • Spectroscopy of Black Holes 
    Tokgöz, Gülnihal (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2015-02)
    ABSTRACT: In this thesis, the 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 ...
  • Spectroscopy of Rindler Modified Schwarzschild Black Hole 
    Sakallı, İzzet; Mirekhtiary, Seyedeh Fatemeh (Astrophysics and Space Science, Springer, 2014)
    We study quasinormal modes (QNMs) of uncharged Grumiller black hole (GBH). This massive BH has a Rindler acceleration a, and hence it is also called Rindler modified Schwarzschild BH. After reducing the radial equation of ...
  • Spherical-separability of Non-Hermitian Hamiltonians and Pseudo-PT -symmetry 
    Mustafa, Omar; Mazharimousavi, Seyed Habib (Springer, 2009-01)
    Non-Hermitian but PϕTϕ-symmetrized spherically-separable Dirac and Schrödinger Hamiltonians are considered. It is observed that the descendant Hamiltonians Hr , Hθ , and Hϕ play essential roles and offer some “user-feriendly” ...
  • 'Square Root' of the Maxwell Lagrangian versus confinement in general relativity 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (Physics Letters B, Elsevier, 2012)
    We employ the 'square root' of the Maxwell Lagrangian (i.e. \surd(F_{{\mu}{\nu}}F^{{\mu}{\nu}})), coupled with gravity to search for the possible linear potentials which are believed to play role in confinement. It is found ...
  • Stability of generic cylindrical thin shell wormholes 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Amirabi, Zahra (Physical Review D, American Physical Society (APS), 2014)
    We revisit the stability analysis of cylindrical thin shell wormholes which have been studied in literature so far. Our approach is more systematic and in parallel to the method which is used in spherically symmetric thin ...
  • Stability of Spherically Symmetric Timelike Thin-shells in General Relativity 
    Amen, Sarbaz Nabi Hamad (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2017)
    In this thesis we study spherically symmetric timelike thin-shells in 3+1-dimensional bulk spacetime. We first introduce the cut and paste formalism which is used to make thin-shells in general relativity and then we ...
