Octonion Form Of Duality-Invariant Field Equations For Dyons, Mustafa Emre Kansu, Murat Tanişli, Süleyman Demi̇r Jan 2020

Octonion Form Of Duality-Invariant Field Equations For Dyons, Mustafa Emre Kansu, Murat Tanişli, Süleyman Demi̇r

Turkish Journal of Physics

The hypothetical particles dyons, which carry both electric and magnetic charges simultaneously, are widely discussed in application to electromagnetic theory and magnetohydrodynamics. Particularly, the duality-invariant field equations were suggested with suitable definitions of the dyon's electromagnetic characteristics. In this study, we propose an alternative formulation of the duality-invariant field equations for dyons based on octonion algebra. Octonions have been used to express the equations for potentials, field strengths, and sources in a more compact and consistent manner. Additionally, the octonionic form of the energy conservation law for dyons has been derived.


The Effect Of Temperature On Fusion Cross-Sections Of The 8b Proton Halo Nucleus, Murat Aygün Jan 2020

The Effect Of Temperature On Fusion Cross-Sections Of The 8b Proton Halo Nucleus, Murat Aygün

Turkish Journal of Physics

In the present study, I investigate the effect of temperature on fusion cross-sections of the 8B proton halo projectile. For this purpose, I evaluate two different fusion reactions, 8B + 28Si and 8B +58Ni, in the available literature. I apply two different nuclear potentials as a function of temperature. I calculate both fusion cross-sections and nuclear potentials for both reactions and I then compare the theoretical results with the experimental data. This comparison provides an opportunity for a test of different temperature-dependent potentials in explaining the fusion cross-sections with the 8B halo nucleus.

Magnetic Properties Of Mn Doped Crystalline And Amorphous Ge Thin Films Grown On Si (111), İlknur Gündüz Aykaç, Aykut Can Önel, Burcu Toydemi̇r Yaşasun, Leyla Çolakerol Arslan

Turkish Journal of Physics

We investigated the effects of crystalline order on the structural and magnetic properties of ultrathin Mndoped Ge thin films grown by thermal diffusion. The dopant motion which occurs during the annealing stage appears to differ considerably depending upon whether the Ge layer is in a crystalline or an amorphous state. The details of the temperature-dependent magnetization curves reveal that the a-MnGe and c-MnGe films show ferromagnetic property up to 300K and ~250K, respectively. Ferromagnetic Mn5 Ge3 thin film with weakly anisotropic in-plane magnetization is formed on amorphous Ge thin film, while weakly ferromagnetic Mn5 Gex Si3-x nanostructures are developed on …


Anisotropic Magnetoresistance And Planar Hall Effect In Magnetoresistivenife/Pt Thin Film, Erdem Demi̇rci̇ Jan 2020

Anisotropic Magnetoresistance And Planar Hall Effect In Magnetoresistivenife/Pt Thin Film, Erdem Demi̇rci̇

Turkish Journal of Physics

The magnetoresistive NiFe/Pt sensor was fabricated by using standard microlithography and sputter deposition techniques and then the magnetic and magnetotransport properties were investigated. The magnetic properties of the sample show that the easy axis of magnetization prefers a predefined direction along the Hall bar. Moreover, the sample has uniaxial magnetic anisotropy due to the growth-induced magnetic anisotropy. On the other hand, the Anisotropic magnetoresistance (AMR) and the Planar Hall effect (PHE) of the sample were investigated in detail between 0° and 360°. The angle-dependent AMR and PHE signals at the in-plane magnetic field of constant magnitude intersect at certain angles. …

Four-Quark Exotic Mesons, Shahin Agaev, Kazem Azizi, Hayri̇ye Sundu Pamuk

Turkish Journal of Physics

We review our investigations devoted to the analysis of the resonances Zc(3900), Zc(4430), Zc(4100), X(4140), X(4274), α1(1420), Y(4660), X(2100), X(2239), and Y(2175) discovered in various processes by Belle, BaBar, BESIII, D0, CDF, CMS, LHCb and COMPASS collaborations. These resonances are considered as serious candidates to four-quark (tetraquark) exotic mesons. We treat all of them as diquark-antidiquark states with relevant spin-parities, find their masses and couplings, as well as explore their dominant strong decay channels. Calculations are performed in the context of the QCD sum rule method. Thus, the spectroscopic parameters of the tetraquarks are evaluated using the two-point sum rules. …

On-Chip Quantum Optics And Integrated Optomechanics, David Hoch, Timo Sommer, Sebastian Mueller, Menno Poot

Turkish Journal of Physics

Recent developments in quantum computing and the growing interest in optomechanics and quantum optics need platforms that enable rapid prototyping and scalability. This can be fulfilled by on-chip integration, as we present here. The different nanofabrication steps are explained, and our automated measurement setup is discussed. We present an opto-electromechanical device, the H-resonator, which enables optomechanical experiments such as electrostatic springs and nonlinearities and thermomechanical squeezing. Moreover, it also functions as an optomechanical phase shifter, an essential element for our integrated quantum optics efforts. Besides this, the equivalent of a beam splitter in photonics-the directional coupler-is shown. Its coupling ratio …


Pseudoscalar Form Factors Of The $\Delta(1232)$ In Baryon Chiral Perturbation Theory, Yasemi̇n Ünal Jan 2020

Pseudoscalar Form Factors Of The $\Delta(1232)$ In Baryon Chiral Perturbation Theory, Yasemi̇n Ünal

Turkish Journal of Physics

The pseudoscalar current-delta transition form factors are calculated in the framework of relativistic baryon chiral perturbation theory including order $\mathcal{O}(q^4)$. The complex-mass scheme, which is suitable and well-defined for unstable particles, is taken into account as a renormalization scheme. We discuss the low energy behavior of the pseudoscalar $\tilde{g}(Q^2)$ and $\tilde{h}(Q^2)$ form factors and note that the momentum dependence of the form factors is dominated by the pion pole contributions.


Influence Of Annealing On Photoelectric Characteristics And Stability Of Elements Based On Si-Bi$_{2}$Te$_{3-X}$Se$_{X}$, Gurban Ahmadov Jan 2020

Influence Of Annealing On Photoelectric Characteristics And Stability Of Elements Based On Si-Bi$_{2}$Te$_{3-X}$Se$_{X}$, Gurban Ahmadov

Turkish Journal of Physics

In the manufacture of Bi$_{2}$Te$_{3-x}$Se$_{x}$-based elements using two sources of the deposited substance, they were initially annealed at a temperature of 150-200 \textdegree Ñ in a low vacuum. Heat treatment led to a slight increase in short circuit current and an increase in open circuit voltage. When the elements were heated in high vacuum, as well as in atmospheres of argon, nitrogen, hydrogen, helium and other gases, irreversible changes in the characteristics were not detected. Heat treatment of elements at a temperature of 100--150 \textdegree C in oxygen always improves their performance. It is assumed that annealing stimulates the growth …


On Current-Voltage And Capacitance-Voltage Characteristics Of Metal-Semiconductor Contacts, Abdulmeci̇t Turut Jan 2020

On Current-Voltage And Capacitance-Voltage Characteristics Of Metal-Semiconductor Contacts, Abdulmeci̇t Turut

Turkish Journal of Physics

It is expected the fact that the current following across metal-semiconductor (MS) rectifying contact named as Schottky barrier diode(SBDs)and effect of sample temperature on their electrical properties obey thermionic emission (TE) current model. But, it has been seen that the abnormal behaviors in the measured electrical characteristics cannot be exactly under stood by the classical TE transport theory. Intheliterature, the observed abnormal behaviors have been successfully explained by a Gaussian distribution function and by the pinch-off model being interaction of the neighbor patches suggested by Tung and coworkers, the named discrete regions model as "patches" with low barrier placed in …


Network Dynamics Reconstruction From Data, Deni̇z Eroğlu Jan 2020

Network Dynamics Reconstruction From Data, Deni̇z Eroğlu

Turkish Journal of Physics

We consider the problem of recovering the model of a complex network of interacting dynamical units from time series of observations. We focus on typical networks which exhibit heterogeneous degrees, i.e. where the number of connections varies widely across the network, and the coupling strength for a single interaction is small. In these networks, the behavior of each unit varies according to their connectivity. Under these mild assumptions, our method provides an effective network reconstruction of the network dynamics. The method is robust to a certain size of noise and only requires relatively short time series on the state variable …


Stable Anisotropic Single-Layer Of Rete$_2$: A First Principles Prediction, Mehmet Yağmurcukardeş Jan 2020

Stable Anisotropic Single-Layer Of Rete$_2$: A First Principles Prediction, Mehmet Yağmurcukardeş

Turkish Journal of Physics

In order to investigate the structural, vibrational, electronic, and mechanical features of single-layer ReTe$_2$ first-principles calculations are performed. Dynamical stability analyses reveal that single-layer ReTe$_2$ crystallize in a distorted phase while its 1H and 1T phases are dynamically unstable. Raman spectrum calculations show that single-layer distorted phase of ReTe$_2$ exhibits 18 Raman peaks similar to those of ReS$_2$ and ReSe$_2$. Electronically, single-layer ReTe$_2$ is shown to be an indirect gap semiconductor with a suitable band gap for optoelectronic applications. In addition, it is found that the formation of Re-units in the crystal induces anisotropic mechanical parameters. The in-plane stiffness and …


Tunneling Radiation And Quantum Entropy Of A Massive Gravity Black Hole, Gu Qiang Li, Yi Wen Zhuang Jan 2020

Tunneling Radiation And Quantum Entropy Of A Massive Gravity Black Hole, Gu Qiang Li, Yi Wen Zhuang

Turkish Journal of Physics

By using the Parikh-Wilczek (PW) quantum tunneling method, the Hawking radiation of black holes in massive gravity is investigated, the emission rate of particles and the black hole entropy are calculated. It is shown that the emission spectrum is not purely thermal, depends on the increment of the black hole entropy, consists with an accurate unitary theory and supports the standpoint of information conservation. Unlike other modified gravities, the entropy of the massive gravity black hole unexpectedly conforms to the area law just as that of Einstein gravity black hole.


Transfer Matrix In Scattering Theory: A Survey Of Basic Properties And Recent Developments, Ali̇ Mostafazadeh Jan 2020

Transfer Matrix In Scattering Theory: A Survey Of Basic Properties And Recent Developments, Ali̇ Mostafazadeh

Turkish Journal of Physics

We give a pedagogical introduction to time-independent scattering theory in one dimension focusing on the basic properties and recent applications of transfer matrices. In particular, we begin surveying some basic notions of potential scattering such as transfer matrix and its analyticity, multidelta-function and locally periodic potentials, Jost solutions, spectral singularities and their time-reversal, and unidirectional reflectionlessness and invisibility. We then offer a simple derivation of the Lippmann-Schwinger equation and the Born series, and discuss the Born approximation. Next, we outline a recently developed dynamical formulation of time-independent scattering theory in one dimension. This formulation relates the transfer matrix and therefore …


Optimization Of Collection Optics For Maximum Fidelity In Entangled Photon Sources, Kadi̇r Durak Jan 2020

Optimization Of Collection Optics For Maximum Fidelity In Entangled Photon Sources, Kadi̇r Durak

Turkish Journal of Physics

In this report,decoherence sources for entangled photons created by spontaneous parametricdown-conversion phenomenon are studied. The phase and spatial distinguishability of photon pairs from orthogonal crystals reduce the maximum achievable entanglement fidelity. Carefully chosen compensation crystals are used to erase the phase and spatial traces of down-conversion origins. Emission angle of photon pairs also leads to optical path difference and results in phase distinguishability. A realistic scenario is numerically modelled, where the photon pairs with nonzero emission angle gather a phase difference. These pairs can still be collected and manipulated for practical use but the collection optics adds upon the phase …

Quantum Gravity Correction To The Thermodynamic Quantities Of The Charged Drgt Black Hole, Gani̇m Geçi̇m

Turkish Journal of Physics

In this study, in the framework of the Hamilton approach, the quantum gravity effect on Hawking temperature, on the specific heat capacity, and on the stability conditions of the charged de Rham, Gabadadze, and Tolley (dRGT) black hole are investigated by using the tunneling processes of both charged massive scalar and Dirac particles. It is shown that quantum corrected Hawking temperature depends not only on the black hole properties but also on the properties of the tunnelling particles. It is also observed that quantum corrected Hawking temperature is lower than that of the standard Hawking temperature. Also, the specific heat …

Investigating Above-Bandgap And Below-Bandgap Optical Transition In Gabias Epilayers By Photoreflectance Spectroscopy, Ömer Dönmez, Ayşe Erol

Turkish Journal of Physics

We present optical identification of deep level defects in as-grown and annealed GaBixAs$_{1-x}$ (x $=$ 0, 0.013 and 0.015) alloys grown at different temperatures (220 \textdegree C and 320 \textdegree C) by using photo-modulated reflectance (PR) spectroscopy and photoluminescence (PL). The PR measurements are employed at above- and below-bandgap excitations, and the PR line-shape is analyzed by the third derivative functional form (TDFF). The PR at below-bandgap excitation reveals transitions at 0.757 \textpm 0.001 eV and 0.710 \textpm 0.002 eV at 30K and 300K, respectively. Franz-Keldysh oscillations are observed in all samples under above-bandgap excitation at PR measurements, and the …

Scintillation Timing Characteristics Of Common Plastics For Radiation Detection Excited With 120 Gev Protons, James Wetzel, Emrah Tiraş, Burak Bi̇lki̇, Ni̇lay Bostan, Ohannes Kamer Köseyan

Turkish Journal of Physics

The timing characteristics of scintillators must be understood in order to determine which applications they are appropriate for. Polyethylene naphthalate (PEN) and polyethylene teraphthalate (PET) are common plastics with uncommon scintillation properties. Here, we report the timing characteristics of PEN and PET, determined by exciting them with 120GeVprotons. The test beam was provided by Fermi National Accelerator Laboratory, andthescintillators were tested at the Fermilab Test Beam Facility. PEN and PET are found to have dominant decay constants of 34.91 ns and 6.78 ns, respectively.


Weak Deflection Angle Of Black-Bounce Traversable Wormholes Using Gauss-Bonnet Theorem In The Dark Matter Medium, Ali Övgün Jan 2020

Weak Deflection Angle Of Black-Bounce Traversable Wormholes Using Gauss-Bonnet Theorem In The Dark Matter Medium, Ali Övgün

Turkish Journal of Physics

Inthispaper, wefirstusetheopticalmetricsofblack-bouncetraversablewormholestocalculatetheGaussian curvature. Then we use the Gauss-Bonnet theorem to obtain the weak deflection angle of light from the black-bounce traversable wormholes. We investigate the effect of dark matter medium on weak deflection angle using the Gauss-Bonnet theorem. We show how weak deflection angle of wormhole is affected by the bounce parameter a. Using the Gauss-Bonnet theorem for calculating weak deflection angle shows us that light bending can be thought as a global and topological effect.

Turkish Journal of Physics

In the present work, ZnO films were obtained on mesoporous silicon substrates by the method of HF magnetron sputtering of a metallic zinc target in reaction oxygen and argon gas medium. The properties of the ZnO films obtained on mesoporous substrates were studied depending on the ratio of the partial pressures of the working gases (argon/oxygen). X-ray analysis showed that in the process of deposition, the ZnO films of a hexagonal structure were formed. The effect of the porous layer on the structural and luminescent properties of the thin ZnO films was studied. The results showed that the porous silicon …

Frequency And Voltage Dependence Of Electrical Conductivity, Complex Electricmodulus, And Dielectric Properties Of Al/Alq3 /P-Si Structure, İkram Orak, Abdulkeri̇m Karabulut

Turkish Journal of Physics

In order to enhance the capacitance of the Al/p-Si metal-semiconductor structure, the Alq3 thin film was coated between these two layers using the spin coating technique as the interlayer. The electrical conductivity, real and imaginary parts of electric modulus, dielectric loss and dielectric constant parameters were examined at the room temperature by the help of admittance measurements in the 100 kHz to 1 MHz frequency range. The effect of frequency on the dielectric constant and dielectric loss values is negligible at the negative voltage values, up to about 0.8 V, and these values rapidly ascended after 0.8 V. The function …


Size-Dependent Electron Chemical Potential In Nanostructures Derived Fromstatistical Configuration, Desyana Olenka Margaretta, Nadya Amalia, Fisca Dian Utami, Riri Murniati, Sparisoma Viridi, Mikrajuddin Abdullah Jan 2020

Size-Dependent Electron Chemical Potential In Nanostructures Derived Fromstatistical Configuration, Desyana Olenka Margaretta, Nadya Amalia, Fisca Dian Utami, Riri Murniati, Sparisoma Viridi, Mikrajuddin Abdullah

Turkish Journal of Physics

We rederived the fermion distribution function by considering the effect of assembly size. We did not use Stirling approximation to avoid the deviation generated by this approximation for a small number of constituents and small assembly size. Furthermore, we identified that in small systems, the chemical potential should also depend on the assembly size. We also rederived a general expression for the size-dependent chemical potential from a statistical configuration and showed that it is consistent with the results from previously reported theoretical or simulation methods. Finally, we applied the model to derive a size-dependent thermoelectric power factor of nanostructured materials. …

Local Vibrational Modes Of Natural Isotopes Of Substitutional Oxygen In Cdte, Enver Tarhan, Anant K. Ramdas Jan 2020

Local Vibrational Modes Of Natural Isotopes Of Substitutional Oxygen In Cdte, Enver Tarhan, Anant K. Ramdas

Turkish Journal of Physics

We investigated the localized vibrational modes (LVM) of natural oxygen containing $^{16}$O, $^{17}$O, and $^{18}$O isotopes at a substitutional tellurium site in cadmium telluride using infrared absorption spectroscopy at cryogenic temperatures. The main absorption peak observed at 350 cm$^{-1\, }$was formerly attributed to a fundamental LVM mode ($\nu _{0})$ of oxygen at a tellurium site. The relatively weak absorption peaks observed at 331 cm$^{-1\, }$and 340 cm$^{-1\, }$are assigned as the same $\nu_{0}$ mode of the $^{17}$O and $^{18}$O isotopes, respectively, based on their relative intensities and spectral positions. The spectral positions were confirmed with theoretical calculations using a linear …

Field-Free Quantum-Spin-1/2 Xxz Model In Three-Dimensions: Phases, Phase Transitions, And Phase Diagrams By Renormalization Group Theory, Ozan Sabahatti̇n Sariyer

Turkish Journal of Physics

The field-free quantum-spin-1/2 XXZ model is studied in three-dimensions using renormalization group theory. We obtain global phase diagrams and critical properties. We identify zero-temperature quantum phase transitions at isotropic points, as well as long-range order below critical temperatures at all anisotropies. We show that the excitation spectrum is gapless in XY-like, and gapped in Ising-like anisotropy regimes. Besides, internal energy density, specific heat, nearest-neighbor entanglement measures and spin-spin correlations are obtained globally at all temperatures. Our numerical results cover the global range of anisotropy parameter, for both ferromagnetic and antiferromagnetic cases.

Analysis Of Chaotic And Regular Behavior Of Matinyan-Yang-Mills-Higgshamiltonian System, Engi̇n Kandiran, Avadi̇s Si̇mon Hacinliyan

Turkish Journal of Physics

In this study we analyze the Matinyan-Yang-Mills-Higgs (MYMH) system, based on semiclassical solutions to a Yang-Mills model, using Poincaré surfaces of section and the method of averaging. To investigate the possible chaotic behavior for the system, we simulate the trajectories of the system and calculate the Lyapunov exponents. We observe that the system displays weakly chaotic behavior. We search for the existence of approximately conserved quantities for the system using the method of averaging. In this way, we show the existence of four fixed points where period orbits exist.

The reactive wetting process of a flat solid alumina (α-Al2 O3) ceramic surface by metallic aluminum (Al) nanodroplets with different shapes (spherical, cylindrical, and layer) is studied using parallel molecular dynamics (MD) simulations based on a variable charge MD method, with focuses on heat transfer, mass transfer, and the structure of the reactive region at the Al/α-Al2 O3 interface. We find that the diffusion of oxygen (O) atoms from the substrate into the droplet leads to the formation of a continuous layer of reaction product at the interface. The diffusion length of oxygen atoms into the spherical Al droplet is …

Prediction Of Standard Enthalpies Of Formation Of Boron Nitride Nanocones, Fahimeh Shojaie Jan 2020

Prediction Of Standard Enthalpies Of Formation Of Boron Nitride Nanocones, Fahimeh Shojaie

Turkish Journal of Physics

Prediction of the standard enthalpy of formation (ΔfH0298) of boron nitride nanocone (BNNCs) structures with disclination angles 60°, 120°, and 180°is recommended to be performed by the isodesmic reaction approach. NH3, BH3, and N2H4 were selected as key reference compounds. In order to calculate ΔfH0298 of nanocones, we must first calculate the enthalpies of nanocone rings at their apexes. For this purpose, ΔfH0298 values of 40 different structures, such as boron, nitrogen, and hydrogen compounds, have been calculated by combining Gaussian-4 (G4) theory calculations with the isodesmic and other balanced reactions approach. At each stage of the calculations, the previously …

Study Of Kno Scaling In The Emulsion Based Neutrino Experiments, Çağin Kamişcioğlu

Turkish Journal of Physics

KNO scaling was put forward by Koba-Nielsen-Olesen in 1972 and then tested by various experiments up to now. In this paper, the data on charged hadron multiplicity moments with KNO scaling of CHORUS and OPERA, both of them emulsion-based neutrino experiments, are compared. The results are given in detail which is very useful for tuning in MC event generators.
