  • Particle Collision near 1+1- Dimensional Horava-Lifshitz Black Hole and Naked Singularity 
    Mustafa, Halilsoy; Ali, Övgün (Hindawi, 2017-01-16)
    The unbounded center-of-mass (CM) energy of oppositely moving colliding particles near horizon emerges also in 1+1 -dimensional Horava-Lifshitz gravity. This theory has imprints of renormalizable quantum gravity characteristics ...

    Halil, Mustafa (Halilsoy, Mustafa) (International Journal of Theoretical Physics, Springer, 1981)
    We solve the geodesics equation for a charged particle in Bell-Szekeres spacetime. In the same geometry we give the test particle solution of Dirac's equation.
  • A particular thin-shell wormhole 
    Sakallı, İzzet; Övgün, Ali (Springer, 2017-02-09)
    Using a black hole with scalar hair, we construct a scalar thin-shell wormhole (TSW) in 2+1 dimensions by applying the Visser cut and paste technique. The surface stress, which is concentrated at the wormhole throat, is ...

    Mustafa, Omar (INST PHYSICS ACAD SCI CZECH REPUBLIC , Springer(Online publishing), 2004)
    A relativistic extension of our pseudo-perturbative shifted l-expansion technique is presented to solve for the eigenvalues of Dirac and Klein-Gordon equations. Once more we show the numerical usefulness of its results via ...

    Barakat, Thabit; Maen, Odeh; Mustafa, Omar (IOP PUBLISHING LTD, 1998)
    A shifted-l expansion technique is introduced to calculate the energy eigenvalues for the Klein-Gordon (KG) equation with Lorentz vector and/or Lorentz scalar potentials. Although it applies to any spherically symmetric ...
  • The Physical Interpretation of a Painleve‟s Transcendent Space-Time 
    Mustafa, Halilsoy; M., El-Said (General Relativity and Gravitation, Springer, 1993)
    We construct a nondiagonalizable solution of the stationary axially symmetric vacuum Einstein equations involving Painleve transcendents III(V). From the asymptotic behaviour of this solution we identify the corresponding ...
  • Position-dependent-mass: Cylindrical coordinates, separability, exact solvability and PT-symmetry 
    Mustafa, Omar (IOP Publishing, 2010)
    The kinetic energy operator with position-dependent-mass in cylindrical coordinates is obtained. The separability of the corresponding Schrodinger equation is discussed within radial cylindrical mass settings. Azimuthal ...
  • Position-dependent mass Lagrangians: nonlocal transformations, Euler-Lagrange invariance and exact solvability 
    Mustafa, Omar (IOP Publishing, 2015)
    A general nonlocal point transformation for position-dependent mass (PDM) Lagrangians and their mapping into a 'constant unit-mass' Lagrangians in the generalized coordinates is introduced. The conditions on the invariance ...

    Metin, Gürses; Halil, Mustafa (Halilsoy, Mustafa) (Physics Letters, Elsevier, 1978)
    We present pp-wave solutions to the generalized Einstein—Maxwell field theory introduced by Horndeski and to Mansouri- Chang theory of gravitation.
  • Propagator theory of scanning tunneling microscopy 
    Bracher, Christian; Rıza, Mustafa; Kleber, Markus (American Physical Soc, 1997)
    We develop a quantum mechanical scattering theory for electrons which tunnel out of (or into) the tip of a scanning tunneling microscope. The method is based on propagators (or Green functions) for quasistationary scattering ...

    Sakallı, İzzet (International Journal of Modern Physics A, World Scientific Publishing, 2013)
    The quantum spectra of area and entropy of higher dimensional linear dilaton black holes in various theories via the quasinormal modes method are studied. It is shown that quasinormal modes of these black holes can reveal ...

    In this paper, we focus on the quantization of 4−dimensional rotating linear dilaton black hole (RLDBH) spacetime describing an action, which emerges in the Einstein-Maxwell-Dilaton-Axion (EMDA) theory. RLDBH spacetime has ...
  • Quantum particles trapped in a position-dependent mass barrier; a d-dimensional recipe 
    Mustafa, Omar; Mazharimousavi, Seyed Habib (Elsevier, 2006-10-23)
    We consider a free particle, V (r) = 0, with a position-dependent mass m(r) = 1/(1 + ς2r2)2 in the d-dimensional Schrödinger equation. The effective potential turns out to be a generalized Pöschl–Teller potential that ...
