  • Mustafa, Halilsoy (Journal of Mathematical Physics, American Institute of Physics (AIP), 1992)
    The quaternionic version of the Ernst formalism is used to propose an alternative generalization of the Zipoy-Voorhees metric that represents spinning spheroids. Rotating discs and their superposition that generalize the ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa; Amirabi, Zahra (Physical Review D, American Physical Society (APS), 2008)
    We introduce new black hole solutions to the Einstein-Yang-Mills-Born-Infeld (EYMBI), Einstein-Yang-Mills-Born-Infeld-Gauss-Bonnet (EYMBIGB) and Einstein-Yang-Mills-Born-Infeld-Gauss-Bonnet-Lovelock (EYMBIGBL) gravities ...
  • Gürtuğ, Özay; Halilsoy, Mustafa; Sakallı, İzzet (General Relativity and Gravitation, 2003)
    A technique is given to generate coupled scalar field solutions in colliding Einstein - Maxwell (EM) waves. By employing the Bell - Szekeres solution as seed and depending on the chosen scalar field it is possible to ...
  • Saatçı, A.M.; Halilsoy, Mustafa (The Chemical Engineering Journal, 1987)
    We present a more general solution of the standard deep bed filtration equations which explains the initial improvement of effluent quality as a suspension passes through a porous medium. Our solution gives a good ...
  • Mustafa, Omar; Mazharimousavi, Habib S. (Springer, 2006)
    A class of non-Hermitian d-dimensional Hamiltonians with position-dependent mass and their η-pseudo-Hermiticity generators is presented. Illustrative examples are given in 1D, 2D, and 3D for different position-dependent ...
  • Mazharimousavi, Seyed Habib (IOP Science, 2008-06)
    We analyze the zero energy solutions, of a two-dimensional system which undergoes a non-radial symmetric, complex potential V (r,φ). By virtue of the coherent states concept, the localized states are constructed, and the ...
  • 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 ...
  • Halilsoy, Elif; Halilsoy, Mustafa (Physical Review D, American Physical Society (APS), 2004)
    The local isometry between black holes and colliding plane waves is employed to derive new colliding wave solutions in the Einstein-Maxwell-dilaton-axion theory. The technique is applied to the asymptotically nonflat linear ...
  • Mazharimousavi, S. Habib; Halilsoy, Mustafa (Physics Letters B, Elsevier, 2011)
    The interaction between bulk and dynamic domain wall in the presence of a linear / non-linear electromagnetism make energy density, tension and pressure on the wall all variables, depending on the wall position. In [1] ...
  • Halilsoy, Mustafa (Journal of Mathematical Physics, American Isntitute of Physics (AIP), 1993)
    As a supplementary to the general class of solutions published in this journal [J. Math. Phys. 31, 2694 (1990)] we remark that for a specific choice of our seed function we obtain an interesting solution which reduces ...
  • Halilsoy, Mustafa (Europhysics Letters EPL, Institute of Physics (IOP) Publishing, 1986)
    The role of the Bavinonic condition in a previously obtained solution of the Ernst equation is clarified.
  • Özyapıcı, Ali; Rıza, Mustafa; Bilgehan, Bülent; Bashirov, Agamirza (Springer US, 2014)
    Theory and applications of multiplicative and Volterra calculi have been evolving rapidly over the recent years. As numerical minimization methods have a wide range of applications in science and engineering, the idea of ...
  • Halilsoy, Mustafa; Gürtuğ, Özay (Nuovo Cimento B, Springer, 1994)
    We present the NUT generalization of the Curzon metric with its multipole extension. The Schwarzschild quadrupole potential in the prolate spheroidal coordinates turns out to cancel the quadrupole moment of a ...
  • Halilsoy, Mustafa (General Relativity and Gravitation, Springer, 1983)
    We make an alternative approach to Bonnorification by making use of effective Lagrangians for the gravitational fields. Using this technique we obtain a new Einstein-Maxwell solution
  • Mustafa, Omar (Inst Physics Acad Sci Czech Republic, Springer (Online Publishing), 2002)
    The D -dimensional quasi - exact solutions for the singular even - power anharmonic potential V(q)=aq^2+bq^{-4}+cq^{-6} are reported. We show that whilst Dong and Ma's [5] quasi - exact ground - state solution (in D=2) is ...
  • Mustafa, Omar (IOP Publishing, 2015)
    The Deng-Fan potential is used to discuss the reliability of the improved Greene-Aldrich approximation and the factorization recipe of Badawi et al [17] for the central attractive/ repulsive core J( J + 1)/2 mu r(2). The ...
  • Mustafa, Omar (INST PHYSICS ACAD SCI CZECH REPUBLIC, Springer (Online Publishing), 2003)
    The shifted 1/N expansion technique used by El-Said [Phys. Rev. B 61 (2000) 13026], to study the relative Hamiltonian of two interacting electrons confined in a quantum dot, is investigated. El-Said's results from shifted ...
  • Mustafa, Omar; Mazharimousavi, Habib S. (Springer, 2007)
    Ordering ambiguity associated with the von Roos position dependent mass (PDM) Hamiltonian is considered. An affine locally scaled first order differential introduced, in Eq. (9), as a PDM-pseudo-momentum operator. Upon ...
