    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 ...
  • 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 ...
  • The Physics of Non-spherical Compact Objects 
    Mangut, Mert (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2023-09)
    In this thesis, one of the well-known spacetimes named as Zipoy-Voorhees (ZV) or-metric is extended to its charged version via Ernst formalism and is called the charged ZV solution. This spacetime is then further ...
  • Physics on the rotating Earth 
    Saleh, Najm Abdola (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2013-06)
    ABSTRACT: In this thesis we study physics on the rotating Earth by studying the moving coordinate systems and rotating coordinate systems. First, we illustrate briefly some kind of translations like Galilean transformation ...
  • 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 ...

    ABSTRACT: In this thesis we study a quantum particle with position dependent mass (PDM). We start from the general form of the kinetic energy operator in which the physical requirements are considered and then we show that ...
  • 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 ...
