  • 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 
    Abdulrahman, Ibrahim Mustafa (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2016-09)
    This thesis reviews some features of the PDM Lagrangians. We reach the mapping of the PDM equation into a unit-mass Lagrangian in the generalized coordinates by the insertion of a nonlocal point transformation. The invariance ...

    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 ...

    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 ...
  • Quantization of Euclidean Black Holes via the Adiabatic Invariance Method 
    Uğural, Esen (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2016)
    In this thesis, we calculate the entropy of four different types of black holes and show that entropy and area of the considered black holes are equally likely quantized. The quantization of entropy/area of the black holes ...
