A Minimal Fermion-Scalar Preonic Model, Ümi̇t Kaya, Bi̇lgehan Bariş Öner, Saleh Sultanov Jan 2018

A Minimal Fermion-Scalar Preonic Model, Ümi̇t Kaya, Bi̇lgehan Bariş Öner, Saleh Sultanov

Turkish Journal of Physics

A minimal fermion-scalar preonic model containing two fermionic preons and one scalar preon is proposed. This scheme allows prevention of the occurrence of undesired SM-level particles, namely leptons and quarks with unusual electric charges. Similar to the previous FS models, color-octet leptons and color-sextet quarks, which are expected to have masses much lower than the compositeness scale, are predicted. Observation of these particles could provide first indications of preonic models. The FCC/SppC pp option will give an opportunity to probe $m_{q_{6}}$ up to 48/75 TeV and $m_{l_{8}}$ up to 15/27 TeV within 1 year of operation at nominal luminosity. FCC/SppC …

Structural And Permeability Characterization Of Zn-Li Ferrites, M H Mesbah Ahmed, A. K. M. Akther Hossain, Shamima Choudhury

Turkish Journal of Physics

Structural characterization and magnetic properties of Zn-substituted Li ferrites with composition \linebreak Zn$_{x}$Li$_{0.45-x/2}$Fe$_{2.55-x/2}$O$_{4}$ (where x = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5) were studied by varying sintering temperature T$_{S}$ (where T$_{S}$ = 1000, 1050, 1100, 1150, 1200, and 1250 $^{\circ}$C) of the six samples. The single-phase cubic spinel structure was found by XRD patterns and scanning electron microscopy revealed the microstructure of all the samples. Permeability (real, $\mu_{i}'$ and imaginary, $\mu _{i}'')$ was found to increase with Zn substitution and also with sintering temperature. The real part of initial permeability ($\mu_{i}')$ was found to depend on the density and …

Function Mining For The $$-N$_{Ch}$ Correlations In Pp And Pp(Bar) Collisions Based On Symbolic Regression, Elsayed Eldahshan

Turkish Journal of Physics

The investigation and analysis of the correlation between the mean transverse momentum () of charged particles and the charged particle multiplicity ($N_{ch}$) allow physicists to understand the contribution of multiple-parton interactions to the particle production mechanism. A symbolic regression (SR) method, based on gene expression programming (GEP), is proposed for mining a function that describes the -$N_{ch}$ correlation in proton-proton and proton-antiproton (pp and pp(bar)) collisions at collision energies from IRS to LHC. The discovered function simulates and models the correlation between and $N_{ch}$ in wide energy range $s^{1/2}$. In the framework of the proposed GEP model for $-N_{ch}$ correlation, …

Broadband Spectral Splitting Of White Light Via 2d Diffractive Optical Elements, Yalin Başay, Emre Yüce

Turkish Journal of Physics

An effective way of increasing the efficiency of solar cells is to spectrally split sunlight into several frequencies and absorb each frequency using appropriate photovoltaic materials. In this study, we establish a method to show spectral splitting of broadband solar light via iteratively optimized diffractive optical elements. We develop an algorithm in order to calculate 2D holographic patterns that focus two different frequencies to designated positions.

Relativistic Quantum Mechanical Spin-1 Wave Equation In 2 + 1 Dimensionalspacetime, Mustafa Dernek, Semra Gürtaş Doğan, Yusuf Sucu, Nuri̇ Ünal

Turkish Journal of Physics

In this study, we introduce a relativistic quantum mechanical wave equation of the spin-1 particle as an excited state of the zitterbewegung and show that it is consistent with the 2 + 1 dimensional Proca theory. At the same time, we see that in the rest frame, this equation has two eigenstates; particle and antiparticle states or negative and positive energy eigenstates, respectively, and satisfy SO(2,1) spin algebra. As practical applications, we derive the exact solutions of the equation in the presence of a constant magnetic field and a curved spacetime background. From these solutions, we find Noether charge by …


General Solution Of The Schrödinger Equation With Potential Field Quantization, Hasan Hüseyi̇n Erbi̇l Jan 2018

General Solution Of The Schrödinger Equation With Potential Field Quantization, Hasan Hüseyi̇n Erbi̇l

Turkish Journal of Physics

A simple procedure has been found for the general solution of the time-independent Schrödinger equation (SE) with the help of quantization of potential area in one dimension without making any approximation. Energy values are not dependent on wave functions. So, to find the energy values, it is enough to find the classic turning points of the potential function. Two different solutions were obtained, namely, symmetric and antisymmetric in bound states. These normalized wave functions are always periodic. It is enough to take the integral of the square root of the potential energy function to find the normalized wave functions. If …

The Effects Of X-Ray Background On The X-Ray Emission From The Galacticsupernova Remnants, Nergi̇s Cesur, Aytap Sezer, Murat Hüdaverdi̇

Turkish Journal of Physics

We present the results of an X-ray background emission study of the well-known Galactic supernova remnants (SNRs) Cas A, RCW 86, RX J1713.7-3946, and SN 1006 by using the archival Chandra and XMM-Newton X-ray Observatories data. With the advent of detector technologies and increased capability of the spectral resolutions, accurate background modelling for the extended sources, such as SNRs, is getting crucial at the modelling step since it might be effective on estimating the physical parameters of the plasma. For this purpose, we concentrate on the background emission spectral modelling by investigating its spectral parameters and components. Hence, the results …


On Differential Depletion Length Of Schottky Diodes With Copper-Nickel Alloy Metal Of Front Contact, Abdulkadi̇r Korkut Jan 2018

On Differential Depletion Length Of Schottky Diodes With Copper-Nickel Alloy Metal Of Front Contact, Abdulkadi̇r Korkut

Turkish Journal of Physics

This work was prepared in two sections; the first section describes how to alloy Schottky diodes and aims to understand how metal alloys affect the essential parameters of Schottky diodes at the metal-semiconductor interface. The second section covers the varying differential depletion length in (Cu% Ni%)/n-Si/Al binary-alloyed Schottky diodes. After collecting data, the characteristics of Schottky diodes are calculated by plotting them with an increasing percentage ratio of the first element. We see that alloyed Schottky diode characteristics significantly depend on the mass percentage ratio of the first element. Significant results are seen: first, Vbi (built-in potential) directly affects the …

The accuracy of the formulas is checked for two different magnetic field profiles in the Sun.


Gamow-Teller Strength In 56fe Nucleus At Finite Temperatures, Esra Yüksel Jan 2018

Gamow-Teller Strength In 56fe Nucleus At Finite Temperatures, Esra Yüksel

Turkish Journal of Physics

In this work, the effect of temperature on Gamow-Teller strength is investigated using fully self-consistent finite temperature proton-neutron random phase approximation in the 56Fe nucleus. The calculations are performed with Skyrme-type SkM* interaction at T = 0, 1, and 2 MeV. It is shown that temperature effects of the occupation probabilities of states and new excitation channels become possible due to the smearing of the Fermi surface. The Gamow-Teller excitation energies shift downward and new excited states are also obtained in the low-energy region due to the unblocked transitions at high temperatures.


Tailoring The Magnetic Anisotropy Of Cobalt-Gold Thin Films, Cengi̇z Okay, Peri̇han Aksu, Caner Deger, Fi̇kret Yildiz Jan 2018

Tailoring The Magnetic Anisotropy Of Cobalt-Gold Thin Films, Cengi̇z Okay, Peri̇han Aksu, Caner Deger, Fi̇kret Yildiz

Turkish Journal of Physics

Magnetic cobalt-gold thin films (Co$_{x}$Au$_{(1-x)})$ are grown on silicon (100) surfaces by using a sputter deposition technique. Magnetic anisotropy of the films is investigated by ferromagnetic resonance (FMR). Magnetic properties are explored by micromagnetic simulations based on the metropolis algorithm. Effective magnetic anisotropy is gradually increased with Co concentration. In-plane axial anisotropy exists for all samples and it is enhanced with a Co concentration of $\sim $40{\%}, corresponding optimal cluster size, and intercluster separation. Segregation and coalescence of Co clusters caused by different Co concentrations strongly affect magnetic properties of the thin films. Therefore, the study revealed that magnetic behavior …


Solar Flare And Geomagnetic Activity Relations, Volkan Sarp, Ali̇ Kilçik Jan 2018

Solar Flare And Geomagnetic Activity Relations, Volkan Sarp, Ali̇ Kilçik

Turkish Journal of Physics

Two x-ray solar flare parameters (number of flares and peak flux) are compared to geomagnetic and space weather activity indices. The first solar flare parameter, X-ray solar flare number (SFN), is the total number of solar flares observed in a given month. The second one is the monthly maximum of X-ray solar flare peak fluxes (SFP). In order to compare these two parameters, both of them are cross-correlated with some other indices of geomagnetic activity (aa, Dst, and AE indices) and space weather (maximum coronal mass ejection speed index and solar wind speed). Maximum correlation was found ($\sim $0.63) between …

Turkish Journal of Physics

The aim of the present study is to provide a better understanding of the effect and applicability of nuclear potentials on scattering reactions. For this, we investigate the quasielastic scattering data of the $^{11}$Li $+ ~ ^{28}$Si reaction at 319 MeV within the framework of the optical model. In order to obtain the real part of the optical potential, we use ten different potentials, which consist of Proximity 1977 (Prox 77), Proximity 1988 (Prox 88), Broglia and Winther 1991 (BW 91), Aage Winther (AW 95), Christensen and Winther 1976 (CW 76), Bass 1973 (Bass 73), Bass 1977 (Bass 77), Bass …

Analytical Solutions Of Conformable Time, Space, And Time-Space Fractional Kdv Equations, Hasi̇be Hale Karayer, Ahmet Doğan Demi̇rhan, Fevzi̇ Büyükkiliç

Turkish Journal of Physics

In this study, we consider the Korteweg-de Vries (KdV) equation for solitary waves in the domain of conformable fractional calculus. By means of this fractional theory, we obtain exact solutions for time, space, and time-space fractional KdV equations and demonstrate our results graphically according to the fractional order of the related equations. Furthermore, we report that the fractional order in the solution of the time fractional KdV equation is associated with viscosity of the medium by comparing three-dimensional picture presentations of solutions of time fractional KdV and Burgers-KdV equations.

Turkish Journal of Physics

In this research work, a solar cell capacitance simulator (SCAPS-1D) was used in the modeling and simulation of sandwiched perovskite solar cells (PSCSs) with a planar heterojunction structure in the arrangement of the sandwiched model (FTO/ZnO/CZTS/PSCS/CZTS/HTM). Two different configurations, 121 and 111, of the sandwiching absorber layer of the device were simulated and compared with the perovskite without sandwiching, using an absorber layer of step length thickness of 25 nm, and varied from 100 nm to 500 nm. The band gap diagram, I-V characteristics curve, and other parameters were constructed. The best configuration for better performance was then determined, from …


Cosmic Censorship And The Third Law Of Black Hole Dynamics, Koray Düztaş Jan 2018

Cosmic Censorship And The Third Law Of Black Hole Dynamics, Koray Düztaş

Turkish Journal of Physics

Israel's proof of the third law of black hole dynamics is based on the semirigidity assumption, which requires that the areas of the outermost trapped surfaces are preserved. We argue that the condition that the area of the event horizon should not decrease is necessary -but not sufficient- for the semirigidity assumption to hold. It is known that the presence of a naked singularity in the exterior region invalidates Hawking's proof of the area theorem. In this sense, the third law assumes the validity of the strong form of the cosmic censorship conjecture, contrary to general acceptance. Still, one cannot …


Chemical Vapor Transport Synthesis Of A Selenium-Based Two-Dimensional Material, Tali̇p Serkan Kasirga Jan 2018

Chemical Vapor Transport Synthesis Of A Selenium-Based Two-Dimensional Material, Tali̇p Serkan Kasirga

Turkish Journal of Physics

Selenium-based layered materials, and in particular transition-metal diselenides (TMDSs), have intriguing properties in the monolayer limit. Materials such as MoSe$_{2}$, WSe$_{2}$, and NbSe$_{2}$ display striking features such as spin-valley coupling at the valence-band edges and offer great potential for optoelectronics applications. Although a dozen of other TMDSs have been realized or proposed, whether two-dimensional chalcogens are possible or not is still an open challenge. In this work, we show the chemical vapor transport synthesis of a novel, atomically thin selenium-based material on oxidized silicon substrates. This new member of the two-dimensional materials family has a unique Raman spectrum similar to …

Theory And Application Of Hydrogen Formation In Proton-Alkali Atom Collision, Sabbah Abdelwahab Elkilany Jan 2018

Theory And Application Of Hydrogen Formation In Proton-Alkali Atom Collision, Sabbah Abdelwahab Elkilany

Turkish Journal of Physics

The possibility of producing more hydrogen during p-alkali atom collisions is discussed. The coupled static approximation is modified for the first time to make it applicable to the multichannel problem of the collisions of p-alkali atoms. The formation of H (1s) and excited H (in 2s- and 2p- states) in the scattering of p-Li atoms is treated to test the convergence of our method. The modified method is used to calculate the total cross-sections of seven partial waves in a range of energy between 50 and 1000 keV. Our p-Li results are compared with earlier ones.

Effects Of Annealing Temperature On Electrical Characteristics Of Sputtered Al/Al2o3/P-Si (Mos) Capacitors, Şenol Kaya, Erhan Budak, Ercan Yilmaz

Turkish Journal of Physics

The aim of this study is to investigate annealing effects on the electrical characteristics of aluminum oxide (Al2O3) MOS capacitors. Chemical changes after annealing have been characterized using the Fourier transform infrared spectroscopy prior to detailed electrical investigation. The influence of annealing temperature on electrical characteristics has been investigated by capacitance-voltage (C-V) and conductance-voltage (G/ω-V) curves. Effective oxide trap density (Nox), border trap densities (N2bt), and interface trap densities (Nit) were calculated during the electrical analysis. Remarkable changes in the measurements were observed depending on the annealing temperatures. The obtained results demonstrate that the optimum annealing temperature is 450 °C …


Dimension Of Quantum Mechanical Path, Chain Rule, And Extension Of Landau's Energy Straggling Method Using $F^\Alpha$-Calculus, Saleh Ashrafi, Ali Khalili Golmankhaneh Jan 2018

Dimension Of Quantum Mechanical Path, Chain Rule, And Extension Of Landau's Energy Straggling Method Using $F^\Alpha$-Calculus, Saleh Ashrafi, Ali Khalili Golmankhaneh

Turkish Journal of Physics

$F^\alpha$-calculus was recently presented for fractals. We show that the $F^\alpha$-derivative satisfies the chain rule and affirms that the dimension of a quantum mechanical path is two. $F^\alpha$-calculus allows us to extend quantum mechanics to fractal curves. To show the applicability of $F^\alpha$-calculus, we study the fractal model of a particle in a box. $F^\alpha$-calculus is suitable for describing the motion of particles with a fractal route through matter. In addition, we extend Landau's energy straggling method of charged particles to fractals.


Super Inflation Mechanism And Dark Energy From A Cosmological Entropy Perspective, Ali̇ İhsan Keski̇n Jan 2018

Super Inflation Mechanism And Dark Energy From A Cosmological Entropy Perspective, Ali̇ İhsan Keski̇n

Turkish Journal of Physics

Various approaches are developed that provide a unification of the early inflationary epoch of the universe and dark energy (cosmic accelerating expansion case). In one respect, we express this unification in a universal thermodynamic framework within the context of $F\left( T,T_{G} \right)$ gravity, where $T$ represents the torsion invariant and $T_{G}$ is the teleparallel equivalent of the Gauss--Bonnet term. For a Friedmann-Robertson-Walker universe model bounded by the dynamical apparent horizon, we explore the generalized second law of gravitational thermodynamics (GSLT). Finally, we discuss the super inflation mechanism, the deceleration case (radiation and dust regions), and the late time cosmic acceleration …

Turkish Journal of Physics

Ternary Co-Fe-Cu thin films with 78.5-92.4 at.% Co, 4.1-17.9 at.% Fe, and 3.1-3.6 at.% Cu were electroplated at ambient temperature from electrolytes with different relative Fe ion concentrations with respect to the Co ion concentration on the glass substrates coated with indium tin oxide (ITO). It was revealed that the Fe is more easily deposited than Co for all electrolyte conditions. The phase structure of the films changed from a mixture of hcp Co and fcc/hcp Co to a mixture of fcc/hcp Co and bcc Fe and the mean crystallite size diminished with increasing Fe content within the deposits. A …

An X-ray nonthermal spectral investigation of the galactic shell-type supernova remnant (SNR) Vela Jr. using archival data from Chandra for the northern and northwestern rims of the SNR is presented. Spectra were extracted from four emission regions in these rims (three in the northwestern rim and one in the northern). The X-ray spectra of the northwestern rim were well reproduced by a single power-law and the synchrotron model srcut, and for the north rim, the spectra were fitted by a single and a broken power-law, respectively. The spectra of both rims show no line emission. Each spectrum was fit by …


Monte Carlo Simulation Of Dynamic Phase Transition Properties Of Core-Shell Magnetic Nanoparticles With Similar Volumes, Erol Vatansever Jan 2018

Monte Carlo Simulation Of Dynamic Phase Transition Properties Of Core-Shell Magnetic Nanoparticles With Similar Volumes, Erol Vatansever

Turkish Journal of Physics

We implement Monte Carlo simulations to determine dynamic phase transition features of both cubical and spherical nanoparticles composed of spin-1/2 cores surrounded by a spin-1 shell layer. The particles are subjected to an oscillating magnetic field. We plan these particles such that they have similar volumes. It is observed that the nonequilibrium magnetic phase transition temperatures of the particles with similar volumes explicitly depend on their geometrical shapes as well as the system parameters. The cubic one has a higher transition temperature than the spherical one for the small interface coupling, whereas the transition temperature of the spherical particle becomes …

Turkish Journal of Physics

Single production potential of the excited muons at the SPPC-based ultimate muon-proton collider with center-of-mass energy of 116.6 TeV was analyzed. We calculated the production cross-sections and the decay widths of the excited muons with the process of µp → µ*X → γµX. We obtained the normalized transverse momentum and pseudorapidity distributions of the final-state particles to attain the kinematical cuts for the discovery of the excited muons. With these cuts, we determined the mass limits. It was shown that the discovery limits on the mass of the excited muons are 19.6 and 10.1 TeV for λ = mµ* and …

Information-Theoretic Measure Of The Hyperbolical Exponential-Type Potential, Atachegbe Clement Onate, Olukayode Adebimpe, Babatunde Olufemi Adebesin, Adewale Folaranmi Lukman

Turkish Journal of Physics

The approximate analytical solution of the 3-dimensional radial Schrödinger equation in the framework of the parametric Nikiforov-Uvarov method was obtained with a hyperbolical exponential-type potential. The energy eigenvalue equation and the corresponding wave function have been obtained explicitly. Using the integral method, we calculated Shannon entropy, information energy, Fisher information, and complexity measure. It was deduced that the complexity measure calculated using Shannon entropy with information energy and that calculated using Shannon entropy with Fisher information were similar.
