  • 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 ...
  • A quasi-free position-dependent mass jump and self-scattering correspondence 
    Mustafa, Omar; Mazharimousavi, Habib S. (IOP Publishing, 2010-11)
    A quasi-free quantum particle endowed with a Heaviside position-dependent mass jump is observed to experience scattering effects manifested by its by-product introduction of the derivative of the Dirac delta point dipole ...
  • Rotating Thin-Shell Wormhole 
    Övgün, Ali (SpringerLink, 2016-11-08)
    We construct a rotating thin-shell wormhole using a Myers-Perry black hole in five dimensions, using the Darmois-Israel junction conditions. The stability of the wormhole is analyzed under perturbations. We find that exotic ...
  • The shifted-1/N-expansion method for two-dimensional hydrogenic donor states in an arbitrary magnetic field 
    Mustafa, Omar (Institute of Physics (IOP) Publishing, 1993)
    The shifted-1/N-expansion method has been used to study the energy levels for a 2D donor impurity in the presence of an arbitrary magnetic field. Exact analytical expressions for the energy levels at zero- and high-field ...
  • A simple adsorbate model in STM 
    Bracher, Christian; Rıza, Mustafa; Kleber, Markus (Springer-Verlag, 1998)
    We discuss a novel source-theoretical description of the STM based on the concepts of quantum-mechanical scattering theory. As an application of the formalism, we study how the presence of a crystalline adsorbate layer ...
  • A singular position-dependent mass particle in an infinite potential well 
    Mustafa, Omar; Mazharimousavi, Habib S. (Elsevier B.V, 2009)
    An unusual singular position-dependent-mass particle in an infinite potential well is considered. The corresponding Hamiltonian is mapped through a point-canonical-transformation and an explicit correspondence between the ...
