  • Similarity Solutions for Self-Dual SU(2) Fields 
    Halilsoy, Mustafa (Physical Review D, American Physical Society (APS), 1986)
    we present new solutions to Yang's self-dual SU(2) equations. These solutions have the property that they are self-similar, together with some of their elliptical and transcendental extensions.
  • A simple adsorbate model in STM 
    Bracher, Christian; Rıza, Mustafa; Kleber, Markus (Springer-Verlag, 1998)
    We discuss a novel source-theoretical description of the STM based on the concepts of quantum-mechanical scattering theory. As an application of the formalism, we study how the presence of a crystalline adsorbate layer ...
  • Simple Model for Vector Bosons 
    Halil, Mustafa (Halilsoy, Mustafa) (1978)
    Using the analogy between the SL(2,C) gauge theory of gravitation and the Yang-Mills theory, we propose a model for massive vector bosons. The model is based on the Geroch-Held-Penrose treatment of gravitation in which ...
  • Simple System to Measure the Earth's Magnetic Field 
    Akoğlu, Reşat; Halilsoy, Mustafa; Mazharimousavi, S. Habib (Physics Teacher, American Association of Physics Teachers, 2010)
    Our aim in this proposal is to use Faraday's law of induction as a simple lecture demonstration to measure the Earths magnetic field (B). This will also enable the students to learn about how electric power is generated ...
  • 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 ...
  • Solution for Static, Spherically Symmetric Lovelock Gravity Coupled with Yang-Mills Hierarchy 
    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 ...
  • Solution of the Dirac equation in the rotating Bertotti-Robinson spacetime 
    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 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 ...

    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Amirabi, Zahra (Physical Review D, American Physical Society (APS), 2010)
    Recently in (Phys. Rev. D 76, 087502 (2007) and Phys. Rev. D 77, 089903(E) (2008)) a thin-shell wormhole has been introduced in 5-dimensional Einstein-Maxwell-Gauss-Bonnet (EMGB) gravity which was supported by normal matter. ...
  • Stable Magnetic Universes Revisited 
    Tahamtan, Tayebeh; Halilsoy, Mustafa (Astrophysics and Space Science, Springer, 2013)
    A regular class of static, cylindrically symmetric pure magnetic field metrics is rederived in a different metric ansatz in all dimensions. Radial, time dependent perturbations show that for dimensions d>3 such spacetimes ...

    Halilsoy, Mustafa (Classical and Quantum Gravity, Institution of Physics (IOP) Publishing, 1997)
    Sandwich waves in the Einstein–Maxwell theory are expressed globally by introducing step functions at the boundaries. We show that a test particle crossing such a wave zone extracts energy from the sandwich wave.
