In this thesis, the properties of the Bose-Einstein condensation (BEC) in low dimensions are reviewed. Three dimensional weakly interacting Bose systems are examined by the variational method. The effects of both the attractive and the repulsive interatomic forces are studied. Thomas-Fermi approximation is applied to find the ground state energy and the chemical potential. The occurrence of the BEC in low dimensional systems, is studied for ideal gases confined by both harmonic and power-law potentials. The properties of BEC in highly anisotropic trap are investigated and the conditions for reduced dimensionality are derived.

Elastic-plastic stresses in linearly hardening rotating solid disks of variable thickness Orcan, Y; Eraslan, Ahmet Nedim (2002-07-01) The distribution of stress, displacement and plastic strain in a rotating elastic-plastic solid disk of variable thickness in a power function form is investigated. The analysis is based on Tresca's yield condition, its associated flow rule and linear strain hardening material behavior. An analytical solution is obtained and numerical results are presented for different values of the geometric parameters. The validity of the solution is demonstrated by comparing the results with those for a uniform thicknes...
Exact and FDM solutions of 1D MHD flow between parallel electrically conducting and slipping plates Arslan, Sinem; Tezer, Münevver (Springer Science and Business Media LLC, 2019-08-01) In this study, the steady, laminar, and fully developed magnetohydrodynamic (MHD) flow is considered in a long channel along with the z-axis under an external magnetic field which is perpendicular to the channel axis. The fluid velocity u and the induced magnetic field b depend on the plane coordinates x and y on the cross-section of the channel. When the lateral channel walls are extended to infinity, the problem turns out to be MHD flow between two parallel plates (Hartmann flow). Now, the variations of u...
Radiation of dipoles in multilayered cylinder with ferrite layer Aydin, O; Hizal, A (1996-07-26) Radiation characteristics of infinitesimal dipole in multilayered circular cylindrical structure including gyromagnetic media are investigated. Transversal field equations in spectral domain are obtained for gyromagnetic medium in cylindrical coordinates. These expressions are formed into a set of linear differential equations. The solution at each layer is expressed in terms of state transition matrices. Fields are matched at the interfaces. Far fields are evaluated asymptotically. The effects of changing ...
EXACT NUMERICAL-SOLUTIONS FOR RADIATIVE HEAT-TRANSFER IN CYLINDRICAL FURNACES Selçuk, Nevin (1988-05-01) Exact expressions for the distributions of the components of radiative flux density and the radiative energy source term in terms of wall and medium temperature distributions have been formulated for an emitting absorbing medium of constant properties bounded by black walls of a cylindrical enclosure. The accuracy of numerical solutions has been tested on an idealized enclosure for which exact analytical solution of the expressions is possible and shown to have six‐figure accuracy. The exact expressions hav...
Einstein aether gravity Akbaba, Esin; Karasu, Atalay; Department of Physics (2009) In this thesis, we review some basic properties of the Einstein-aether gravity. We derive the field equations from an action and study a subclass of this theory corresponding to the Einstein-Maxwell like theory. We also show that the Gödel type metrics are also exact solutions of this theory. Furthermore, we determine the observational constraints on the dimensionless preferred parameters of this theory using the parametrized post- Newtonian formalism. We stress that none of calculations and discussions are...
