In this study, the atomic structure and the glass formation process of Co90 Zr10 metallic glass alloy were studied by molecular dynamic simulation based on the embedded atom method using four different cooling rates. The average atomic volume and the potential energy of the system were observed to be strongly dependent on the cooling rate during rapid solidification, and the glass transition temperature decreased with decreasing cooling rate. The radial distribution functions and the structure factors derived from molecular dynamics simulations at 300 K agreed well with the experimental and other molecular dynamics results. The coordination numbers calculated at 300 …
Effect Of Left-Handed Materials In Surface Plasmon Excitation And Propagationlength, Ari̇f Engi̇n Çeti̇n
Effect Of Left-Handed Materials In Surface Plasmon Excitation And Propagationlength, Ari̇f Engi̇n Çeti̇n
Turkish Journal of Physics
We investigated the dispersion relation of surface plasmons (SPs) excited in a medium comprised of a left-handed material (LHM) layer. We investigated different light polarizations in SP excitation along an LHM-metal interface. We studied SP excitation through a classical Kretschmann geometry, employing an LHM interlayer between a dielectric and a metal layer. Using this three-layer configuration, we investigated the effect of LHM medium on characterizing SP propagation length, which is directly related to the energy of the surface waves.

Design And Test Of An Apparatus For Transient Measurements Of The Thermalconductivity And Volumetric Heat Capacity Of Solids, Florian Gather, Ekrem Güneş, Peter J. Klar
Turkish Journal of Physics
Knowledge of the thermal conductivity (κ) of solids is crucial for all thermoelectric devices. A new approach in transient measurement to determine this value as well as electric conductivity (σ) and the Seebeck coefficient (S) is presented here. This approach can be combined with current steady-state methods. A cylindrical sample is mounted between two heat-flux sensors that can be heated or cooled at their outer ends. The input signals defining the heat fluxes at the sensors can be any arbitrary function of time, although some waveforms yield more valid results. The method is evaluated by employing a one-dimensional numerical model …

Modified Newton's Gravitational Law From Deformed Poisson Bracket, Ch'ng Han Siong
Turkish Journal of Physics
In this paper, we obtain the modified Newton's gravitational law from deformed Poisson bracket motivated by the generalized uncertainty principle. The modified Newton's gravitational law that we obtain contains a term that plays an important role only in the regime of first order in $\bar{\beta}$. In the ordinary situation or condition, the modified Newton's gravitational law reduces to the conventional Newton's gravitational law.
Lorentz-Violating Effects In Single W Boson Production At The Lhc, Serdar Spor, İnanç Şahi̇n
Lorentz-Violating Effects In Single W Boson Production At The Lhc, Serdar Spor, İnanç Şahi̇n
Turkish Journal of Physics
We investigate the Lorentz-violating effects of Standard Model Extension (SME) in single W boson production process pp → pγp → p W- q' X at the Large Hadron Collider (LHC). We employ the Weizsacker-Williams approximation for photons emitted from one of the incoming proton beams and consider γq → W- q' as a subprocess in the proton-proton collision. The behavior of the differential cross-section for various orientations of the constant background fields is obtained by taking into account longitudinal and transverse polarization states of the final W bosons.

Effect Of Al Doping On The Magnetic And Elastic Properties Of Fe65 Ni35 Invar Alloys, Asli Çakir
Turkish Journal of Physics
Invar alloys have great importance due to their low thermal expansion coefficient. The effect of Al doping on Fe65 Ni35 Invar alloy was investigated by temperature-dependent magnetization and elastic modulus measurements. First, 0.44 at% and 2.24 at% of Al were substituted for Ni. Then X-ray diffraction measurements, Rietveld refinements, and scanning electron microscopy studies were performed to understand the effect of Al-doping on the face-centered cubic structure. The elastic modulus of Fe65 Ni35 and the Al-doped samples were measured in the temperature range 300 ≤ T ≤ 870 K using impulse excitation. The temperature dependence of magnetization and elastic modulus …

Theoretical Description Of The Two-Color Photoelectron Spectra Process Of Hydrogen: Comparison Between Tdse Calculation And Kroll And Watson Approach, Souhaila Chaddou, Soumia Chqondi, Abdelmalek Taoutioui, Abdelkader Makhoute
Turkish Journal of Physics
We present a theoretical study of the main characteristics of two-color photoionization of hydrogen atoms by short strong laser pulses. Our numerical approach is performed by numerically solving the time-dependent Schrödinger equation for a hydrogen atom interacting with Ti:sapphire laser radiation combined with its 15th harmonic. The energy spectra obtained by the direct numerical solution of the Schrödinger equation are compared with those given by the Kroll and Watson perturbative approach. This comparison allows us to check the reliability of the latter approximation.

Total Sunspot Number Calculation Based On Flare Production Potential Of Sunspot Groups: Reconstruction Of Ssn And Its Relation To Some Geomagnetic Indices, Ahmet Burak Karslioğlu, Burçi̇n Dönmez, Ali̇ Kilçik
Turkish Journal of Physics
In this study, we modified the previously introduced X-ray flare production potential (FPP) of each modified Zurich sunspot group based on its X-ray flare peak flux. Then, using these FPPs, the daily total sunspot number (Zurich number) calculation equation was modified; thus, new sunspot number data (CRz) were produced. We also compared ISSN and CRz with some geomagnetic indices (Dst, the maximum CME speed, and Ap indices). We found that the CRz data describe the geomagnetic indices quite well compared to ISSN. By using the regression equation between CRz and the sunspot area, the CRz dataset was recalculated back to …

The Effect Of Phenylboronic Acid-Based Self-Assembled Monolayers On Theperformance Of Organic Field-Effect Transistors (Ofets), Tuğbahan Yilmaz Aliç
Turkish Journal of Physics
The dielectric/semiconductor interface is one of the most important components strongly affecting the performance of organic field-effect transistors (OFETs). To improve OFET parameters, we applied a series of phenylboronic acid derivatives as self-assembly molecules between dielectric and organic semiconductor layers. Device performance parameters, especially threshold voltage, current on/off ratio, and subthreshold slope, were improved. To elucidate the mechanism, dielectric/semiconductor interfaces were analyzed using atomic force microscope and contact angle techniques.

Nonlinear Frequency Conversion Of Light Inside A Microcavity, Emre Yüce
Turkish Journal of Physics
Changing the color of light in a small mode volume is essential for applications that require on-chip operation. Microcavities are profound structures given their property to confine light in a small mode volume. Here, I numerically investigate the frequency conversion of light in a microcavity and show that the frequency converted light intensity is distinguished from an open medium such as an optical fiber or a nonlinear crystal. I observe that the frequency converted light intensity increases with increased rate of change of the refractive index of the microcavity. Notably, this study shows that the intensity of the frequency converted …

Application Of The Fractional Oscillator Model To Describe Damped Vibrations, Sergo Rekhviashvili, Arsen Pskhu, Praveen Agarwal, Shilpi Jain
Turkish Journal of Physics
We consider a model of damped vibrations based on fractional differentiation. The model given is completely consistent with the classical model of vibration with viscous damping. We find the relation between the order of fractional differentiation in the equation of motion and Q-factor of an oscillator. The proposed approach seems more appropriate for the physical nature of the described system. The experiment with a vibrating piezoelectric plate, performed as part of the study, showed good agreement with the model and confirmed that the fractional oscillator model can be used to describe strongly damped vibrations.

We present experimental and theoretical investigations of pHEMT heterostructures with AlGaAs/InGaAs/GaAs quantum wells (QWs) and/or a delta-doped layer, which can be used as active regions in transistors operating in the 4-18 GHz frequency range. Using the electrochemical capacitance-voltage setup ECV Pro we, for the first time, experimentally observed a concentration peak from the near-surface delta layer of the pHEMT structure together with a peak of QW enrichment. The capacitance of the electrolyte-semiconductor contact was measured by Agilent LCR-meter, which was connected to the electrochemical cell of ECV Pro through a specially designed relay module. Using numerical simulation of the electronic …
Effect Of Annealing Temperature On Structural, Electrical, And Uv Sensingcharacteristics Of N-Zno/P-Si Heterojunction Photodiodes, Şenol Kaya
Turkish Journal of Physics
The aim of this study is to investigate the influences of annealing temperature on initial device characteristics and their correlations with ultraviolet (UV) radiation sensitivity of n-type zinc oxide/p-silicon (n-ZnO/p-Si) heterojunction photodiodes. Evolutions on the crystalline structure, surface morphology, ideality factor, barrier potential, interface state density, and donor concentration were systematically analyzed during the initial device characterizations before testing the UV sensitivities of the photonic devices. The results demonstrate that the sensitivity of each n-ZnO/p-Si photodiode annealed at various temperatures was linearly correlated with different UV illumination intensities. The devices annealed at 750 ºC and 550 ºC exhibit more sensitive …

Localizable Entanglement Of Isotropic Antiferromagnetic Spin-1/2 Chain, İzzet Paruğ Duru, Şahi̇n Aktaş
Turkish Journal of Physics
The bounds of entanglement on antiferromagnetic (AF) isotropic Heisenberg spin-1/2 chain including dipole- dipole interaction (D) were investigated. The Quantum Monte Carlo method based on loop algorithm was employed to calculate the two-spin and single-spin expectation values mediating the lower and upper bounds. It was revealed that D and Bz (the applied magnetic field) were pivotal parameters in controlling either entanglement creation/extinction or entanglement enhancement/weakening. Rival regions indicated a revival phenomenon depending on the temperature for various strengths of D which also showed a nonmonotonic behavior under certain Bz identifying critical points. Even if thermal agitations break the stability of …

Investigations are ongoing to develop cheaper THz time-domain spectroscopy (THz-TDS) systems. In this context, many studies have been published in which multimode laser diodes (MLDs) are used as light sources in THz- TDS systems. There is another method for cost-reduction. Photomixing employs two single-mode LDs and does not require a pulse laser, and then realizes a reduced-cost system. A comprehensive report has been presented by examining the work done up to now. In these studies, it has been shown that the characteristics of MLDs, the effects of antenna structures on THz signal production, the difficulty of collimation of the MLD …

Turkish Journal of Physics
The total bremsstrahlung (BS) generated in compounds of BaCl2.2H2 O, CuCl2: 2H2O, Pb(CH3 COO)2.3H2O, PbCl2, Pb(NO3)2, and CuSO4.5H2 O by 90Sr was investigated using a Si(Li) detector to determine the dependence of the BS spectra on the modified atomic number (Zmod) of compounds in the photon energy range of 1-100 keV. A continuous decrease in the Zmod dependence of the bremsstrahlung spectra in the energy range of 1-30 keV was observed, followed by a slow increase thereafter, i.e. in the range of 30-100 keV.

An Investigation Of Structural Properties And Surface Morphologies Ofelectrochemically Fabricated Nanocrystalline Ni-Co-Cu/Ito Deposits Withdifferent Compositions, Umut Saraç, Mevlana Celaletti̇n Baykul
Turkish Journal of Physics
In this study, nanocrystalline ternary Ni-Co-Cu/ITO deposits with different compositions were produced by using the electrochemical deposition technique from a sulfate-based bath solution with different Co ion concentrations. It was revealed that an increment in the Co ion concentration gives rise to an enhancement in the Co content but leads to a decrement in the Ni and Cu contents of the deposit structure. The Co-Cu and Ni-Cu exhibited normal codeposition behavior, while the Co-Ni showed anomalous codeposition behavior irrespective of the bath concentration. The change in the degree of the anomalous codeposition was also investigated according to the Co ion …

Turkish Journal of Physics
It is known that the Takahashi-Tanimoto identity-based solution in open string field theory derives a kinetic operator which is a sum of twisted Virasoro generators. Applying the infinite circumstance description of conformal field theory, we derive continuous Virasoro algebra associated with the kinetic operator. Mode expansions of Virasoro generators and the modified BRST charge are given.
Autonomous Piston Engine Guided By The Transduction Of Radiation Pressure Inoptomechanical Brownian Motors, Yusuf Gül
Turkish Journal of Physics
We consider the autonomous piston engine in a coupled cavity scheme in an optomechanical setup. Treating the radiation field as working fluid, we investigate the transduction of virtual photons due to ground state excitations. Rabi-like energy splittings and Casimir effect are shown by avoided crossing in the eigenfunction spectrum. Second order coherence functions are employed to analyze the bunching of the cavity and mechanical mode in optomechanical implementation of Brownian motors. The imbalance in occupation numbers of the working modes is investigated for the power for work extraction. We explore the guidance of the radiation field in work extraction. We …

Turkish Journal of Physics
Higher-order cross sections for the production of a W boson in association with jets in the electron decay channel are presented in this study. Cross sections were calculated in a fully differential way using a computational framework based on proton-proton collisions at a center-of-mass energy of 13 TeV. The differential cross section predictions in the fiducial phase-space were compared at next-to-leading order (NLO) and next-to-NLO (NNLO) in perturbative quantum chromodynamics (pQCD). The differential results are reported for the variables including the jet multiplicity, the invariant mass of the W boson, transverse momentum, the jet rapidity, and the electron pseudorapidity that …

Thin-Shell Wormholes From Kiselev Black Holes, Peter Kuhfittig
Turkish Journal of Physics
This paper discusses the theoretical construction of thin-shell wormholes from Kiselev black holes. We assume a barotropic equation of state for the exotic matter on the shell. While most of these wormholes are unstable to linearized radial perturbations, a limit argument is used to show that under certain conditions, stable solutions can be found.
