  • Unified Bertotti-Robinson and Melvin Spacetimes 
    Halilsoy, Mustafa; Mazharimousavi, S. Habib (Physical Review D, American Physical Society (APS), 2013)
    We present a solution for the Einstein-Maxwell (EM) equations which unifies both the magnetic Bertotti-Robinson (BR) and Melvin (ML) solutions as a single metric in the axially symmetric coordinates t,ρ,z,φ. Depending on ...
  • Uninformed Hawking radiation 
    Sakallı, İzzet; Övgün, Ali (EPL, IOP Publishing (Institute of Physics), 2015-04-24)
    We show in detail that the Parikh-Wilczek tunneling method (PWTM), which was designed for resolving the information loss problem in Hawking radiation (HR) fails whenever the radiation occurs from an isothermal process. ...
  • Variational approach to the tunneling-time problem 
    Bracher, Christian; Rıza, Mustafa; Kleber, Markus (AMER PHYSICAL SOC, 1999)
    Tunneling problems are characterized by different quantum time scales of motion. In this paper, we identify a tunneling time scale, which is based on a simple variational principle. The method utilizes the stationary e ...
  • Wave propagation in a medium with position-dependent permittivity and permeability 
    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 ...
  • Wave Propagation in an Inhomogeneous Matter 
    Alhmod, Zainab Sauod Muhmmed (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2014-08)
    ABSTRACT: We study the waves spread in the media, non-linear and non-homogeneous is basic and widespread Problem in physics, which is the subject of our research. We derive the equation of Maxwell for the wave equation ...
  • η-weak-pseudo-Hermiticity generators and exact solvability 
    Mustafa, Omar; Mazharimousavi, Habib S. (Springer, 2006)
    Exact solvability of some non-Hermitian η-weak-pseudo-Hermitian Hamiltonians is explored as a byproduct of η-weak-pseudo-Hermiticity generators. A class of V (x) = V (x) + i W (x) potentials is considered, where the imaginary ...
  • η-Weak-Pseudo-Hermiticity Generators and Radially Symmetric Hamiltonians 
    Mustafa, Omar; Mazharimousavi, Seyed Habib (SPRINGER/PLENUM PUBLISHERS, 2008-07)
    A class η-weak-pseudo-Hermiticity generators for spherically symmetric non- Hermitian Hamiltonians are presented. An operators-based procedure is introduced so that the results for the 1D Schrödinger Hamiltonian may very ...
