  • An attractive φ4 theory in light-front coordinates 
    Yalnız, Gökhan (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    We study an attractive φ4 interaction using Tamm-Dancoff truncation with light-front coordinates in 3 + 1 dimensions. The truncated theory requires a coupling constant renormalization, we compute its β function non-perturbatively, ...
  • Aspects of finite size effects on Bose-Einstein condensation 
    Seymen, Sema. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2015., 2015.)
    In this thesis, the number of particles calculations of Pathria for a 3 dimensional box is shortly reviewed. After that, the works of Toms and Kirsten which use the Mellin Barnes integral representation and heat kernel ...
  • Black holes in an expanding universe 
    Şenikoğlu, Yorgo. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2016., 2016.)
    By performing transformations on the isotropic forms of di erent metrics, new cosmological black hole solutions were obtained by generalizing the static solution, the Schwarzchild solution, the McVittie and the Kerr ...
  • Born-oppenheimer approximation for some singular systems 
    Akbaş, Hacı. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2016., 2016.)
    In this thesis we try to solve the energy spectrum of heavy particles in three body singular system by using the Born-Oppenheimer approximation. Heavy particles are carrying attractive Dirac-Delta function potential so, ...
  • Dirac-delta potentials on a lattice 
    Tok, Tarık. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2018., 2018.)
    In this thesis, the Dirac delta potential on a one dimensional infinite lattice structure [2] and its band gaps [3] are reviewed. Then, Green’s function and regu larization & renormalization process for the bound states in ...
