  • Modified theories of gravity via alternative couplings and their cosmological analyses 
    Kavuk, Mehmet. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2015., 2015.)

  • Multiparameter generalization of deformed particle algebras 
    Arıkan, Ali Serdar. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2004., 2004.)
    In this study, we generalize deformed boson and fermion algebras by considering as many deformation parameters as possible. The restriction on the number of deformation parameters emerges from the relations leaving the ...

    Yenice, Kamil Mehmet. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1985., 1985.)
    In this work we consider the path integrals in quantum theory and some of their applications to homogeneous spaces from the semiclassical point of view. We begin with the basic principles underlying the Feynman path integral ...
  • Performance of transition radiation tracker at CERN-ATLAS experiment

  • Prime statistics in particle algebras 
    Erol, Cem. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    The importance of the fermion algebra extends to all branches of physics. It is characterized by the important property that at most one particle can be present in a quantum state with otherwise same quantum numbers. In ...
  • Primordial and late-time inflation in Brans-Dicke cosmology 
    Çalık, Mehmet. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    The basic motivation of this work is to attempt to explain the rapid primordial inflation and the observed slow late-time inflation by using the Brans-Dicke theory of gravity. We show that the ratio of primordial and ...
  • Quantum group structures associated with invariances of some physical algebras 
    Kayserilioğlu, Ufuk. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    In this study, the anticommuting spin algebra is introduced and it is shownto be invariant under the action of the quantum group SOq=-1(3). Furthermore, itsrepresentations and Hopf algebra structure are studied and found ...
  • Quantum phenomena and shape dynamics 
    Dündar, Furkan Semih. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2018., 2018.)
    In this thesis, we considered quantum phenomena (Unruh effect) in Shape Dy namics, version of Bohmian Mechanics that is compatible with Mach’s Principle, and a solution (gravitational collapse of a spherically symmetric ...
  • Radio frequency energy recovery for particle accelerators 
    Yıldız, Veli. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
    During the operation of particle accelerators considerable amount of power coming to RF cavities is converted to heat in load resistors placed after RF cavities. When the CERN’s Super Proton Synchrotron is analyzed as an ...
  • Search for axions with micromegas detectors in the cern cast experiment 
    Yıldız, Süleyman Cenk. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    The CAST experiment is searching for the axion, which is a light, weakly interacting pseudoscalar particle, that is proposed to solve the so called Strong Charge-Parity Problem. The axions CAST is looking for are produced ...
  • Solar axion production and detection mechanisms 
    Özuğurel, Umut Deniz. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    Production mechanisms of the axion particle in the Sun as well as the detection principle and the data analysis methods that the CAST experiment is based on are reviewed. It is shown that the solar axion production can be ...
  • Stereographic coordinates for unitary quantum groups 
    Arıkan, Ali Serdar. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1998., 1998.)
    In this thesis, unitary matrix representation of quantum group SUq(2) is studied in terms of stereographic coordinates z, z* and its central unitary phase u. It is observed that this parametrization of SUq(2) can be regarded ...
  • The braided algebra and its Jordan-Schwinger construction in terms of Q-deformed fermionic oscillators

    The standard bosonic and fermionic Jordan-Schwinger constructions for the Lie algebra of SU(2) are reviewed in this thesis. It is shown that the Jordan-Schwinger constructions of the quantum group with q as deformation ...
  • Theoretical foundations of axion particles 
    Ezer, Cemile. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    The Standard Model of particle physics has solved the problem of giving masses to quarks and leptons by introducing the Higgs particle which soon will be searched at the Large Hadron Collider at CERN. Another problem of ...
  • Uncertainty and certainty relations for the q-oscillator 
    Türkmen, Fatma Nur. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    The uncertainty and certainty relations for the momentum and position operators for the q-oscillator and Fibonacci oscillator are investigated in this thesis. The onedimensional q-oscillator, the two-dimensional q-oscillator ...
