Bianchi-V Cosmological Models With Viscous Fluid And Constant Deceleration Parameter In General Relativity, Sharad Kandalkar, Pramod Khade, Mohini Gaikwad
Bianchi-V Cosmological Models With Viscous Fluid And Constant Deceleration Parameter In General Relativity, Sharad Kandalkar, Pramod Khade, Mohini Gaikwad
Turkish Journal of Physics
In this paper we discuss the variation law for Hubble's parameter, average scale factor in spatially homogenous anisotropic Bianchi Type V space-time that yields a constant value deceleration parameter. Using the law of variation for Hubble's parameter, exact solutions of Einstein's field equations are obtained for Bianchi-V space time filled with viscous fluid in two different cases where the universe exhibits power law and exponential expansion. We investigate a number of solutions with constant and time varying cosmological constant together with variable and constant bulk viscosity. We find that the constant value of deceleration parameter is reasonable for the present …
Symmetry And The Order Of Events In Time. The Asymmetrical Order Of Events In Time In A Reversible Energy Converter, Ben-Zion Ginzburg, Randy Wayne
Symmetry And The Order Of Events In Time. The Asymmetrical Order Of Events In Time In A Reversible Energy Converter, Ben-Zion Ginzburg, Randy Wayne
Turkish Journal of Physics
The positive increase of entropy that occurs in irreversible processes has always served as a criterion for distinguishing the past from the future. The unerring ability of the Second Law of Thermodynamics to predict the order of events in time based on a change of entropy in macroscopic systems has led to the concept of the thermodynamical arrow of time. In this paper we analyze a cyclical reversible energy converter, in which thermal energy is converted into useful work without any net change of entropy. While it is usually assumed that time is an outsider in the equations of reversible …
Symmetry And The Order Of Events In Time. A Proposed Identity Of Negative Mass With Antimatter, Randy Wayne
Symmetry And The Order Of Events In Time. A Proposed Identity Of Negative Mass With Antimatter, Randy Wayne
Turkish Journal of Physics
In another paper in this series, we developed a symmetrical theory of mass which describes how systems of positive mass and negative mass will respond to an input of thermal energy. A system composed of positive mass or negative mass will respond to an input of thermal energy in opposite ways. For example, if a system composed of positive mass expands in response to radiation from a hot body, a system composed of negative mass will contract. Likewise, if the system composed of positive mass contracts when brought in communication with a cold body, a system composed of negative mass …

Thermodynamics Of Liquid Alkali Metals Using Pseudopotential Perturbation Scheme, Jagendra Kamalsinh Baria, Ashvinkumar Ramaniklal Jani
Turkish Journal of Physics
Recently proposed model potential of Baria and Jani is used with the exchange and correlation effect of Sarkar et al. to calculate internal energy (Enthalpy), Entropy and Helmholtz free energy of liquid Na, K, Rb and Cs at various temperatures with the variational approach. The parameter of the potential is determined with the standard zero pressure condition. The structure factor derived by Percus-Yevick solution for hard sphere fluids which is characterized by hard sphere diameter \sigma is used. A good agreement between theoretical investigations and experimental findings has confirmed the ability of the model potential to the liquid alkali metals.
Exactly Solvable Potentials From Decemvirate Power Potential, Nilamoni Saikia
Exactly Solvable Potentials From Decemvirate Power Potential, Nilamoni Saikia
Turkish Journal of Physics
A transformation method is presented which consist of a coordinate transformation and a functional transformation that allow generation of exact analytic bound state solutions of the Schrodinger Green's function equation. The method proposed here, which involves the generation of an exact analytic solution from solvable decemvirate power potential within the framework of Green's functions technique, makes it possible to generate a number of solved quantum systems for original quantum systems with multi-term potentials. The generated quantum systems are in general energy dependent with a single normalized eigenstate. A method has been devised to convert a subset of the generated quantum …

The Influence Of Confinements On The Photon Flux Spectra In Amorphous Silicon Quantum Dots, Moafak Cadim Abdulrida, Nidhal Moosa Abdul-Ameer, Shatha Mohammad Abdul-Hakeem
Turkish Journal of Physics
We have theoretically calculated the photon flux of radiative recombination in amorphous silicon quantum dots (a-SiQDs) at room temperature. These quantum dots have been ranged in their diameter 1 to 4 nm. The convolution of probability density function of deepest energy states of conduction P_C(E) and valence P_V(E) bands within the capture volume was adopted. The behavior of this function can be classified into four regions according to the quantum dot size. The effect of spatial and quantum confinements on the peak value of photon flux must be taken into account. We found that a blue shift is classified by …

Te Surface Waves In Dielectric Slab Sandwiched Between Lhm Slabs, Ass'ad I. Ass'ad, Hassan S. Ashour
Turkish Journal of Physics
In this work, the dispersion relation for TE surface waves has been derived for a slab waveguide constructed from a dielectric material slab sandwiched between two thick layers of left-handed material (LHM). The dispersion relation and the power flow were numerically solved for a given set of parameters: the structural factor, dielectric slab thickness, and the operating frequency on the effective refractive index and power flow. We found that the wave effective refractive index decreases with thickness increase as well as increase in frequency. We found that the effective refractive index increases slightly with increase of structural factor. Also, the …
Dynamics And Noise Of Fiber-Grating Semiconductor Lasers Affected By The Line-Width Enhancement Factor, Salah Abdulrhmann
Dynamics And Noise Of Fiber-Grating Semiconductor Lasers Affected By The Line-Width Enhancement Factor, Salah Abdulrhmann
Turkish Journal of Physics
This paper numerically investigates the effect of the line-width enhancement factor on the dynamics and the intensity noise of InGaAs/InP lasers pumping in the wavelength of 980 nm at the strong optical feedback limit. The investigation is performed based on an improved time-delay rate equation model of a single-mode laser. The analyses are performed in terms of the temporal trajectory of the laser intensity, bifurcation diagram, relative intensity noise and injection current. The simulation results indicate that the laser, under strong optical feedback, mainly operates in CW, pulsation or chaos operation depending on the line-width enhancement factor and injection current …

Turkish Journal of Physics
Nanocrystalline amorphous ribbons of composition Fe_{70.5}Cr_3Cu_1Nb_3Si_{13.5}B_9 prepared by rapid solidification technique have been studied in the present work. Amorphicity of the ribbons has been confirmed by X-ray diffraction. Crystallization temperatures were identified by X-ray diffraction and crystallization products were analyzed by XRD. When annealed below the crystallization temperature, i.e. when the sample is in amorphous state, temperature dependence of permeability curves were characterized by sharp increase of permeability and subsequent fall to lower value near ferro-paramagnetic transition temperature, which is typical Hopkinson effect for soft ferromagnetic single phase material. Under devitrification, when the sample is in a two phase state, …
A Fresh Look At Thermal Field Emission From Tungsten Tip, Ahmed Abdurrahman Ahmed Al-Tabbakh
A Fresh Look At Thermal Field Emission From Tungsten Tip, Ahmed Abdurrahman Ahmed Al-Tabbakh
Turkish Journal of Physics
Electron emission from clean tungsten tips has been investigated at different temperatures and applied electric field. Emission mechanism is analyzed on the basis of the Fowler-Nordheim (FN) model and a parameter extraction model based on elimination of field enhancement factor. The suggested extraction model of the physical and geometrical parameters is found fairly adequate to resolving the apparently confusing behavior of these parameters and shedding light on the emission mechanism. The observed linear FN plots at low temperatures confirm the predominating effect of the applied field on the electron emission. At elevated temperatures, emission is found to fall in the …

Estimation Of Radiological Risk Due To Concentration Of ^{238}U, ^{226}Ra, ^{232}Th And ^{40}K In Soils Of Different Geological Origins In Northern India, Rohit Mehra, Manmohan Singh
Turkish Journal of Physics
Radioactivity of nuclides ^{238}U, ^{226}Ra, ^{232}Th and ^{40}K was measured in soil by \gamma-ray spectrometry using a HPGe detector. A criterion was set in order to analyse soil samples from plain, semi-hilly and hilly areas in northern India. More than three \gamma-ray energy peaks were used for the determination of ^{226}Ra and ^{232}Th activity concentrations to obtain more accurate results. Some of these peaks have interfering energies, which was caused by the limited resolution of the detector, but they were resolved theoretically and used in the analysis because of their significance in reducing the random error to its minimum level. …

Branching Of The W(H_4) Polytopes And Their Dual Polytopes Under The Coxeter Groups W(A_4) And W(H_3) Represented By Quaternions, Mehmet Koca, Nazi̇fe Koca, Mudhahir Al-Ajmi
Turkish Journal of Physics
4-dimensional H_4 polytopes and their dual polytopes have been constructed as the orbits of the Coxeter-Weyl group W(H_4), where the group elements and the vertices of the polytopes are represented by quaternions. Projection of an arbitrary W(H_4) orbit into three dimensions is made preserving the icosahedral subgroup W(H_3) and the tetrahedral subgroup W(A_3). The latter follows a branching under the Coxeter group W(A_4). The dual polytopes of the semi-regular and quasi-regular H_4 polytopes have been constructed.

Turkish Journal of Physics
CLIC is a linear e^+e^- collider project which employs a drive beam to accelerate the main beam. Various portions of the drive beam provide RF power for corresponding units of the main linac through energy extracting RF structures. CLIC can operate over a wide range of center-of-mass energies, from 150 GeV to 3 TeV. In addition to e^+e^- collider, \gamma\gamma and \gamma e colliders based on CLIC can be realized. In order to generate high energy photons, a Free electron laser (FEL) produced from the CLIC drive beam linac can be used. In this paper we show that the CLIC …

Admixture Of Higher Multi-\Hbar\Omega Configurations In The Calculation Of Electron Scattering Form Factors Of Some 1p-Shell Nuclei, Ammar A. Al-Sa'ad
Turkish Journal of Physics
A semi-microscopic approach that modifies the 1p-shell model wave functions through the admixture of higher p-shells configurations from multi-\hbar\omega model space is submitted in this work. The longitudinal form factors of C2 transitions in ^7Li and ^{15}N, and the transverse form factors of M1 transition in ^{12}C are calculated in the framework of this approach with the emphasis on the reproduction of the second lobe data. It is found that a slight contribution of the higher multi-p-shells with the 1p-shell in the modified initial and/or final states wave functions is sufficient for giving the best description to the form factors …

Heat Capacity Of Trapped Bosons In A Combined Harmonic-Lattice Potential, Azza M. Elbadry
Turkish Journal of Physics
In this paper, the heat capacity per particle C(T)/Nk_B of the trapped bosons in a combined harmonic-lattice potential is calculated within the semicalssical approximation. The main effects which can alter the ideal gas are included simultaneously in the present approach. The calculated results show that the heat capacity has a significant dependence on the lattice depth and temperature. Classical results are recovered at sufficiently high temperature, and that it reproduces the Dulong-Petit law type. Moreover, the behavior of the heat capacity in a deep lattice can be used as an indicator for the quantum phase transition superfluid-Mott insulator. It decreases …

Hydrogen Implantation Effects On The Electrical And Optical Properties Of Inse Thin Films, Atef Fayez Qasrawi, Khaled Faisal Ilaiwi, Antonio Polimeni
Turkish Journal of Physics
The effects of hydrogen ion implantation on the structural, electrical and optical properties of amorphous InSe thin films have been investigated. X-ray diffraction analysis revealed no change in the structure of the films. An implantation of 7.3 x 10^{18} ions/cm^2 decreased the electrical conductivity by three orders of magnitude at 300 K. Similarly, the conductivity activation energy, which was calculated in the temperature range of 300-420 K, decreased from 210 to 78 meV by H-ion implantation. The optical measurements showed that the direct allowed transitions energy band gap of amorphous InSe films has decreased from 1.50 to 0.97 eV by …

In this paper, a homogeneous principle is proposed to seek the space-time scaling invariant traveling wave solutions expressed by power functions for some fractional differential equations. Applying this principle to generalized fractional Benjamin-Ono equations and generalized fractional ZakharovKuznetsov equations, the traveling wave solutions expressed by power functions have been obtained under some parameter conditions.
Near-Resonant Diurnal Reactions: A Physical Model Applicable To Origin Of Life Processes, Eddwin Budding, Cüneyt Aki, Osman Demi̇rcan, Bülent Gündüz, Güngör Gündüz, Mehmet Emi̇n Özel
Near-Resonant Diurnal Reactions: A Physical Model Applicable To Origin Of Life Processes, Eddwin Budding, Cüneyt Aki, Osman Demi̇rcan, Bülent Gündüz, Güngör Gündüz, Mehmet Emi̇n Özel
Turkish Journal of Physics
We adopt that the large residual chemical potential energy (CPE) among reagents of the biosphere constitutes the key physical problem posed by life. We associate the formation of this CPE with the near-resonant behaviour of a two-stage `A-B' molecular process that behaves as a self-sustaining parametric oscillator. Under suitable conditions, such an oscillator generates CPE when forced by a periodic (daily) insolation. The net growth factor required to explain the current mean excess of biospheric CPE is \sim 5 x 10^{-12} d^{-1}. This aligns with the mean exponential coefficient of secular oxygen generation in the terrestrial atmosphere. It is also …

The static elastic constants (C_{11}, C_{12} and C_{44}), pressure derivative of elastic constants, pressure derivative of bulk modulus, propagation velocities of longitudinal and transverse waves in [100], [110] and [111] directions and Young modulus are investigated through computations using the higher-order perturbation theory based on pseudopotential formalism, in which we have applied our own proposed model potential for GaP, GaAs and GaSb semiconductor compounds. In the present calculations, two local-field correction functions are employed to consider exchange and correlation effects. The numerical values of the aforesaid properties are found to be sensitive to the selection of the local-field correction function …
Determination Of Barrier Height Temperature Coefficient By Norde's Method In Ideal Co/N-Gaas Schottky Contacts, Abdulmeci̇t Turut
Determination Of Barrier Height Temperature Coefficient By Norde's Method In Ideal Co/N-Gaas Schottky Contacts, Abdulmeci̇t Turut
Turkish Journal of Physics
We have formed the ideal Co/n-GaAs Schottky barrier diodes (SBDs) by magnetron DC sputtering. The experimental current-voltage data of the Co/n-GaAs SBD are almost independent of the sample temperature and quite well obey the thermionic emission model from 100 K to 320 K. We have showed that the temperature coefficient of the barrier height can be determined using Norde's method instead of the temperature-dependent capacitance-voltage measurements or the flat-band barrier height values because the thermionic emission current dominates in the ideal SBDs. We have obtained a barrier height temperature coefficient value of \alpha = 0.41 meV/K for Co/n-GaAs SBDs used …

Effect Of Zinc Incorporation On The Density Of Defect States In A-Se_{85}Te_{15} Glassy Alloy, Shikha Shukla, Santosh Kumar
Turkish Journal of Physics
Present work incorporates the study of d.c. conductivity measurements at high electric fields in vacuum evaporated thin films of Se_{85-x}Te_{15}Zn_x (x = 0, 2, 4, 6 and 10) glassy alloys. Current-Voltage (I-V) characteristics have been measured at various fixed temperatures. In these samples, at low electric fields, ohmic behavior is observed. However, at high electric fields (E \sim 10^4 V/cm), non ohmic behavior is observed. An analysis of the experimental data confirms the presence of space charge limited conduction (SCLC) in the glassy materials studied in the present case. From the fitting of the data to the theory of SCLC, …

Structural And Magnetic Characterization Of Bi_{0.9}Ca_{0.1}Fe_{0.98}X_{0.02}O_3 (X = Mg, Al, Ti, V) Polycrystalline Multiferroic Compounds, Mansour Al-Haj
Turkish Journal of Physics
The multiferroic compounds Bi_{0.9}Ca_{0.1}Fe_{0.98}X_{0.02}O_3, X = Mg, Al, Ti, V, were prepared by the solid state reaction method and were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, vibrating sample magnetometry, and differential scanning calorimetry. The compounds were found to have the rhombohedral perovskite-like structure, accompanied by the existence of small amounts of the usual impurity phases Bi_2Fe_4O_{9} and Bi_{25}FeO_{40}. The appearance of weak ferromagnetism is due to partial destruction of the spiral spin structure due to lattice distortion and suppression of oxygen vacancies. The magnetic transition temperatures of the compounds are 342, 346, 349, and 345 °C, respectively.
