  • Newtonian Cosmology 
    Zebari, Hamza Saber Saeed (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2020)
    In this work, we have used the Friedmann equation of general relativity with quantum correction terms to the Newtonian potential to obtain the modified Friedmann equation with quantum correction. The behavior of the solution ...
  • Non-Hermitian d-dimensional Hamiltonians with position-dependent mass and their η-pseudo-Hermiticity generators 
    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 ...
  • Non-Hermitian Hamiltonian versus E = 0 localized states 
    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 ...
  • Nonlinear Electromagnetics in Flat and Curved Spacetime 
    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 ...
  • Nonsingular colliding wave solutions in Einstein-Maxwell-dilaton-axion theory E. Halilsoy and M. Ha 
    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 ...
  • Note on: "Domain wall universe in the Einstein--Born--Infeld theory" Phys. Lett. B 679 (2009) 160 
    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] ...
  • Note on ‘‘Large family of colliding waves in the Einstein–Maxwell theory’’ 
    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 ...
  • On a Class Transcendent Solution in EM Theory 
    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.
  • On multiplicative and Volterra minimization methods 
    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 ...
  • On Some Properties of the NUT-Curzon Space-Time 
    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 ...
  • On the Generation of a Class of Einstein-Maxwell Solutions 
    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
  • On the quasi-exact solvability of a singular potential in D-dimensions: Confined and unconfined 
    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 ...
  • 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 ...
