Conventional Heavy Quarkonium systems, Charmonium and Bottomonium, are believed to be composed of a heavy quark and anti-quark pair. These systems are investigated by di erent methods resulting from di erent approaches to Quantum Chromodynamics (QCD), such as Lattice QCD, E ective Theories and Sum Rules. In this thesis we study the spectrum of Charmonium and Bottomonium using a non-relativistic Quark Model. Assuming one gluon exchange for the short distances and a linear confining potential for long distances we derive Breit-Fermi interaction Hamiltonian and calculate the spectra arising from this Hamiltonian. Also we calculate the partial widths of E1 and M1 radiative decays.

Investigation of microwave metamaterial based on H-shaped resonator in a waveguide configuration and its sensor and absorber applications
Sabah, Cumali; Taygur, Mehmet Mert; ZORAL, EMİNE YEŞİM (2015-04-13)
A microwave metamaterial (MTM) based on H-shaped resonator in a waveguide configuration is introduced and investigated both numerically and experimentally for X-band frequencies. The proposed model is designed and fabricated on both sides of the substrate and exhibits strong magnetic resonance at around 10.5GHz. Additionally, it has very simple design which improves and simplifies the fabrication process. Besides, only one single slab is used in the simulation and experiment which provides a reduction in th...
Study of the Influence of Transition Metal Atoms on Electronic and Magnetic Properties of Graphyne Nanotubes Using Density Functional Theory
Alaei, Sholeh; Jalili, Seifollah; Erkoç, Şakir (Informa UK Limited, 2015-01-01)
Density functional theory calculations were used to study the adsorption of three transition metal atoms (Fe, Co, and Ni) on the external surface of two zigzag and two armchair graphyne nanotubes. The most stable position for the adsorption of all three metal atoms on all nanotubes is on the acetylenic ring. The metal atom remains in the plane of the acetylenic ring and makes six bonds with neighboring carbon atoms. Fe and Co complexes are magnetic and show different properties such as metal, semimetal, hal...
Analysis of Conformal Frequency Selective Surface Radome
Dalkilic, Akin; Alatan, Lale; Top, Can Baris (2014-04-11)
In this paper, the transmission characteristics of a conformal frequency selective surface (FSS) radome which is designed to operate in Ku-band is compared to its planar counterpart. The radome is designed to have narrow band-pass characteristics with a performance that is independent of the polarization and the angle of incidence of the incoming wave. The optimum dimension of the radome is optimized through the simulations of the infinite planar structure. Then, the performance of the conformal structure i...
Investigations of spinodal dynamics in asymmetric nuclear matter within a stochastic relativistic model
Yılmaz, Osman; ACAR, FERİDE PINAR; Saatci, S.; GÖKALP, AHMET (Springer Science and Business Media LLC, 2013-03-01)
Early development of spinodal instabilities and density correlation functions in asymmetric nuclear matter are investigated in the stochastic extension of the Walecka-type relativistic mean field including coupling with rho meson. Calculations are performed under typical conditions encountered in heavy-ion collisions and in the crusts of neutron stars. In general, growth of instabilities occur relatively slower for increasing charge asymmetry of matter. At higher densities around rho = 0.4 rho(0) fluctuatio...
Production of single heavy charged leptons at a linear collider
De Pree, Erin; Sher, Marc; Turan, İsmail (American Physical Society (APS), 2008-05-01)
A sequential fourth generation of quarks and leptons is allowed by precision electroweak constraints if the mass splitting between the heavy quarks is between 50 and 80 GeV. Although heavy quarks can be easily detected at the LHC, it is very difficult to detect a sequential heavy charged lepton, L, due to large backgrounds. Should the L mass be above 250 GeV, it cannot be pair-produced at a 500 GeV ILC. We calculate the cross section for the one-loop process e(+)e(-)-> L tau. Although the cross section is s...
