  • ELECTROWEAK THEORY OF ASSOCIATED STRANGENESS PRODUCTION VIA NEUTRINO-NUCLEON INTERACTION 
    goa alaye, Samuel; bekele, Gashaw Major Advisor (PhD) (Haramaya university, 2018-12)
    In this thesis, we present a fully relativistic description of associated production via NC neutrino-nucleon weak interaction. In the Lab frame where the target nucleon is at rest; the kinematics and dynamics of the ...
  • RELATIVISTIC DESCRIPTION OF ELECTRON-MUON SCATTERING REACTION 
    tesfaye, Mengistu; bekele, Gashaw Major Advisor (PhD) (Haramaya university, 2018-02)
    In this thesis, detailed derivations of the spin-average invariant amplitude and hence the differential cross-section for unpolarized electron-muon elastic scattering are made by using lowest-order Feynman diagrams. It ...
  • PPLICATION OF PERTURBATION THEORY TO SCHRÖDINGER EQUATION OF HYDROGEN ATOM (CASE OF FINITE-SIZE NUCLEUS) 
    kolbi, Urgesa; mengesha, Elias Major Advisor (PhD) (Haramaya university, 2017-08)
    Corrections in energy levels of hydrogen atom are calculated using first-order perturbation theory of hydrogen atom with finite size proton. The finite size proton is used by introducing the charge density of the proton. ...
  • SPECIFIC HEAT ESTIMATION FOR FERROMAGNETS WITHIN THE FRAMEWORK OF THE ISING MODEL 
    bekele, Dawit; bekele, Gashaw Major Advisor (PhD) (Haramaya university, 2017-08)
    This project presents the specific heat estimation for ferromagnetic material using the Ising model within the framework of the mean field approximation. First, a calculation is performed to obtain expression for partition ...
  • QUANTUM MECHANICAL STUDY OF THE INTERACTION OF RADIATION WITH MATTER 
    ahmedmuz adem, Anwar; mengesha, Elias Major Advisor (PhD) (Haramaya university, 2017-05)
    In this project an attempt has been made, first to present the quantum mechanical formalism of the interaction of radiation with matter, the photoionisation of an atom and the photodisintegration of a deuteron. For this ...
  • BERRY'S PHASE IN QUANTUM MECHANICS AND ITS APPLICATIONS 
    menza, Mebratu; mengesha, Elias Major Advisor (PhD) (Haramaya university, 2016-01)
    The aim of this project is to explain Aharonov-Bohm effect and to study the spin-half particle using Berry phase. If we consider Quantum Hamiltonian with external magnetic field that varies in time, we can solve the time ...
  • QUANTIZATION OF RELATIVISTIC DIRAC FIELD AND THE SPIN STATISTICS THEOREM 
    tasew, Gashaw; mengesha, Elias Major Advisor (PhD) (Haramaya university, 2016-01)
    In this project, attempt was made to develop the basic ideas of second quantization for a relativistic Dirac field using Lagrangian formalism in the four-dimensional space. In particular, concentration was made on the ...
  • QUANTUM EFFECTS IN THE DYNAMICS OF TRAPPED BOSE CONDENSED GASES 
    sulamo, Firdawok; bekele, Gashaw Major Advisor (PhD) (Haramaya university, 2016-01)
    In this project, quantum theory of a weakly interacting, dilute Bose gas is presented using the formalism of second quantization. First, a calculation is performed to obtain an expression for the Hamiltonian operator ...
  • QUANTUM THEORY OF THE THERMODYNAMICS OF AN IDEAL BOSE GAS 
    bezabih, Emawayish; bekele, Gashaw Major Advisor (PhD) (Haramaya university, 2016-01)
    In this project work, quantum theory of the thermodynamic properties of an ideal Bose gas is presented using quantum statistics. First a calculation is performed to obtain expressions for partition function and for ...
