  • On the ro-vibrational energies for the lithium dimer; maximum-possible rotational levels 
    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 ...
  • On the spectroscopic structure of two interacting electrons in a quantum dot 
    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 ...
  • Ordering Ambiguity Revisited via Position Dependent Mass Pseudo-Momentum Operators 
    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 ...

    Övgün, Ali; Halilsoy, Mustafa (2016-01-04)
    This poster is presented in KSM2015, Frankfurt, Germany
  • Particle Collision near 1+1-D Horava-Lifshitz Black Holes 
    Halilsoy, Mustafa; Övgün, Ali (2016-01-07)
  • 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 ...
  • Particle Motion in BS Space-Time 
    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 ...
  • PDM-Charged Quantum Particles Moving in Magnetic Fields 
    Algadhi, Zeinab Saleh Musbah (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2020)
    The classical and quantum mechanical correspondence for constant mass settings is used, along with some nonlocal point transformation (NPT), to find the position-dependent mass (PDM) classical and quantum Hamiltonians. ...
  • Perihelion Precession in the Solar System 
    Kanzi, Sara (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2016-09)
    In this thesis, we study about perihelion precession in the solar system, one of the most interesting aspects of astrophysics that include both aspects of General Relativity and classical mechanics. The phenomenon, by which ...
  • Perturbed coulombic potentials in dirac and Klein-Gordon equations 
    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 ...
  • Perturbed Coulomb potentials in the Klein-Gordon equation via the shifted- l expansion technique 
    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 ...
  • Ph.D Defense- Studies on Thin-shells and Thin-shell Wormholes 
    Ali, Övgün (2016-07-18)
  • 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 ...
