Turkish Journal of Physics
Incubators serve as essential tools for maintaining optimal temperature, humidity, and atmospheric gas composition for cell cultures. Their applications span across various fields like cell biology, microbiology, and molecular biology. However, in many cell-based studies, observing cellular changes often necessitates moving cells out of the incubator for microscope examination. Unfortunately, exposing cells to an environment that does not support healthy growth can undermine the reliability of test outcomes. In this article, we present a groundbreaking solution: a cost-effective, portable incubator system seamlessly integrated with a smartphone for real-time characterization tests. This innovation offers comparable imaging capabilities and maintains an environment …

A Compendious Review Of Majorization-Based Resource Theories: Quantum Information And Quantum Thermodynamics, Gökhan Torun, Onur Pusuluk, Özgür Esat Müstecaplioğlu
Turkish Journal of Physics
The field of quantum resource theory (QRT) has emerged as an invaluable framework for the examination of small and strongly correlated quantum systems, surpassing the boundaries imposed by traditional statistical treatments. The fundamental objective of general QRTs is to characterize these systems by precisely quantifying the level of control attainable to an experimenter. In this review article, we refrain from providing an exhaustive summary of the extensive literature on QRT. Rather, our focus centers on a specific subliterature founded upon the theory of majorization. The primary aim is to augment our comprehension of genuine quantum phenomena manifested across diverse technological …

Development And Benchmark Of A 1d3v Electrostatic Pic/Mcc Numerical Code For Gas Discharge Simulations, İbrahi̇m Arda, İsmai̇l Rafatov
Turkish Journal of Physics
Gas discharge plasmas are low-temperature nonequilibrium plasmas that have a wide range of scientific and technological applications. The particle-in-cell/Monte Carlo collision (PIC/MCC) method is a reliable approach for numerical analyses and simulations of such plasmas. In this study, we first provide a detailed description of the basics of this method. We then verify the programme code that we developed in Fortran by benchmarking the code against a widely referred reference study simulating a radiofrequency capacitively coupled plasma (RFCCP) in helium for various discharge conditions. We show that the results of the present study are in good agreement with that of …

ℼ± -,ℼ0-Meson Electroweak Decays Within Relativistic Quark Model Based On Point Form Of Poincaré-Invariant Quantum Mechanics, Vadzim Haurysh, Viktor Andreev
Turkish Journal of Physics
In the course of work the integral representation of ℼ0-meson form-factor of ℼ0 → γγ process has been obtained within relativistic quark model based on point form of Poincaré-invariant quantum mechanics taking into account anomalous magnetic moments of κυ and κⅾ quarks. The parameters obtained using pseudoscalar density constant gℼ± , current masses of υ- and ⅾ-quarks as well as decay constant ℼ± → ℓ±νℓ were used for numerical modeling of Fℼ0γ(t) form-factor in time-like region. Similar calculations for ℼ0 → γγ decay characteristics with reference to quark …
Speeding The Generation Of Giant Entangled States Using Low-Frequency Modulations, Abdelaziz Benseghir, Azeddine Messikh, Ahmed Bouketir
Speeding The Generation Of Giant Entangled States Using Low-Frequency Modulations, Abdelaziz Benseghir, Azeddine Messikh, Ahmed Bouketir
Turkish Journal of Physics
In this paper, we generalize the shortcuts to adiabacity for the quantum Rabi model by simultaneously modulating its two components, namely, the two-level system and the cavity mode. This will eliminate the counterrotating terms which in turn helps to simulate the Rabi model by the Jaynes-Cummings model without requiring a largely detuned light-matter coupling. We focus on the low-frequency modulations since it is easy to realize them experimentally. The results show that these modulations can significantly shorten the evaluation time, generate much larger entanglement cat states, and robust against imperfection of time evaluation and dissipation.
Magnetic Response Of A Two-Dimensional Viscous Electron Fluid, Aydin Cem Keser, Oleg Sushkov
Magnetic Response Of A Two-Dimensional Viscous Electron Fluid, Aydin Cem Keser, Oleg Sushkov
Turkish Journal of Physics
It has been established that the Coulomb interactions can transform the electron gas into a viscous fluid. This fluid is realized in a number of platforms, including graphene and two-dimensional semiconductor heterostructures. The defining characteristic of the electron fluid is the formation of layers of charge carriers that are in local thermodynamic equilibrium, as in classical fluids. In the presence of nonuniformities, whirlpools and nontrivial flow profiles are formed, which have been directly imaged in recent experiments. In this paper, we theoretically study the response of the electron fluid to localized magnetic fields. We find that the electric current is …
Sensing Translocating Polymers Via Induced Magnetic Fields, Şahi̇n Büyükdağli
Sensing Translocating Polymers Via Induced Magnetic Fields, Şahi̇n Büyükdağli
Turkish Journal of Physics
The requirement to boost the resolution of nanopore-based biosequencing devices necessitates the integration of novel biosensing techniques with reduced sensitivity to background noise. In this article, we probe the signatures of translocating polymers in magnetic fields induced by ionic currents through membrane nanopores. Within the framework of a previously introduced charge transport theory, we evaluate the magnetic field signals generated by voltage- and pressure-driven DNA translocation events in monovalent salt solutions. Our formalism reveals that in voltage-driven transport, the translocating polymer suppresses the induced magnetic field via the steric blockage of the ion current through the midpore. In the case …

Exploring The High Energy Frontiers Of The Milky Way With Ground-Based Gamma-Ray Astronomy: Pevatrons And The Quest For The Origin Of Galactic Cosmic-Rays, Ekrem Oğuzhan Angüner
Turkish Journal of Physics
Cosmic rays (CRs) are charged particles that arrive at Earth isotropically from all directions and interact with the atmosphere. The presence of a spectral knee feature seen in the CR spectrum at 3 PeV energies is an evidence that astrophysical objects within our Galaxy, which are known as 'Galactic PeVatrons', are capable of accelerating particles to PeV energies. Scientists have been trying to identify the origin of Galactic CRs and have been looking for signatures of Galactic PeVatrons through neutral messengers. Recent advancements in ground-based γ-ray astronomy have led to the discovery of 12 Galactic sources emitting above 100 TeV …

Probing Exotic Neutral Current Interactions With Coherent Elastic Neutrino-Nucleus Scattering, Mehmet Demi̇rci̇
Turkish Journal of Physics
The Exotic Neutral Current introduces new interactions beyond standard model (BSM) which consist of all possible four-fermion nonderivative Lorentz structures: scalar (S), pseudoscalar (P), vector (V), axial-vector (A), and tensor (T). In this work, we investigate the prediction of this model via the Coherent Elastic Neutrino-Nucleus Scattering (CE$\nu$NS). The differential cross-section spectrum of CE$\nu$NS for three nuclei in regards to experiment advancement are calculated in the framework of this model independent proposal using recent obtained bound. We present the ratio of this exotic model with the SM for various threshold energies. Significant bound is shown lie in the lower threshold …

Gold Thin-Film Based Narrow-Band Perfect Absorbers For Near-Ir Frequencies, Serap Aksu
Gold Thin-Film Based Narrow-Band Perfect Absorbers For Near-Ir Frequencies, Serap Aksu
Turkish Journal of Physics
Perfect absorbers have received significant attention due to their tunable and extraordinary absorptive behaviour of light at selected wavelenghts. Such absorption can be achieved by the means of nanostructured materials with various types of flexibility. Despite these advantages nanofabrication is a challenging process. In this study, we manufacture and characterize a gold thin-film based ultra narrow-band perfects absorber that does not require nanostructures for full absorption of the incident light. Perfect absorption is based on Fabry-Perot interference created using a metal-insulator-metal triple layer. The fabrication involves precise deposition of a gold film (35 nm) and silicon nitride dielectric film (110-170 …
