  • 3+1 formulation in Newton-Cartan gravity 
    Aras, Ulaş. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    In this thesis, we will give a review of torsion-free Newton- Cartan theory. We will start by doing a large c expansion of general relativity and we will restrict ourselves to a few leading orders. After obtaining Newton-Cartan ...
  • Adiabatic solutions in general relativity and boundary symmetries 
    Kutluk, Emine Şeyma. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    We investigate adiabatic solutions to general relativity for a spacetime with spatial slices with boundary, by Manton approximation. This approximation tells us for a theory with a Lagrangian in the natural form, a motion ...
  • Aspects of nonrelativistic strong gravity 
    Hamamcı, Efe. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    We carry out the leading order (LO) large c expansion to GR in the presence of odd powers with the tools provided by Newton-Cartan (NC) gravity. As a result, a set of di eomorphism invariant LO equations are found. The odd ...
  • Aspects of supersymmetric mechanics 
    Çapku, Zürbiye. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    Supersymmetry is a space time symmetry which relates bosons to fermions or vice verca. It requires that for each particle there has to be an anti- particle with the same mass. Along this thesis some supersymmetric Lagrangian ...
  • Instanton methods and the dyon atom 
    Pazarbaşı, Cihan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2015., 2015.)
    In quantum mechanics, perturbation theories have crucial importance for almost any practical calculation. However, perturbative expansions are generally asymptotic series due to the singularities on the complex couping ...
  • On the large c expansion of general relativity 
    Ergen, Mert. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    This paper will start with the classical description of gravity. It will next explain the mathematical tools that will be used to carry classical gravity to a geometrical frame. After demonstrating the covariant formulation ...
  • Perturbative and non-perturbative physics from singularities 
    Pazarbaşı, Cihan. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022), 2022)
    A function that representing a physical quantity has singularities which con tain perturbative or non-perturbative information about the physical system under investigation. Moreover, the theory of resurgence tells us that ...
  • Scaling solutions of N = 2 supergravity and holography 
    Mirfendereski, Delaram. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    The 4D N = 2 SUGRA is the low energy limit of Type II string theory compactified on a Calabi-Yau three-fold. The theory contains BPS black holes with multi centered configurations consisting of bound states of dyonic ...
  • Symmetries global, local and asymptotic, applications of noether and covariant phase space methods 
    Şimşek, Ceyda. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2017., 2017.)
    Primarily, global, local and asymptotic symmetries will be described and their correspondence in the conservation laws will be shown in this thesis. The latter will be managed by Noether’ s theorems and Covariant Phase ...
  • The inverse scattering method of general relativity 
    Eygi, Esat Erdem. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    In this thesis, the Inverse Scattering Method of Belinski and Zakharov is studied in the context of general relativity. The physical interpretation of solitons is estab lished, as well as the connection between solitons ...
