Temperature-Dependent Quantum Beats Between Neutral And Charged Excitons In Monolayer Mose2, İbrahi̇m Sarpkaya

Turkish Journal of Physics

We studied the interaction between the neutral and charged excitons of monolayer MoSe2 at various temperatures via quantum beat spectroscopy in the time domain. We introduced temperature as an efficient control knob to regulate the relative photoluminescence intensities of the neutral and charged excitons to obtain maximum quantum beat resolution. Also, our quantum beat measurements under different temperatures indicate that the decoherence time of the coupled exciton-trion state slightly decreases from 530 fs at 3.5 K to 420 fs at 63 K with increased temperature due to the low-energy acoustic phonon-induced dephasing.

Alternative Scenarios For The Lhc Based Electron-Proton Collider, Ahmet Nuri̇ Akay, Burak Dağli, Bora Ketenoğlu, Ari̇f Öztürk, Saleh Sultansoy

Turkish Journal of Physics

Construction of the ERLC (twin LC) collider tangential to LHC will allow investigating ep collisions at essentially higher center-of-mass energies than ERL-50 and LHC based ep collider. Luminosity estimations show that values well exceeding 1034 cm−2s−1 can be achieved for ERLC and HL-LHC based ep colliders. Certainly, proposed ep colliders have great potential for clarifying QCD basics and new physics search in addition to providing precise PDFs for adequate interpretation of the LHC experimental data. Another alternative to the ERL-50 is to construct an e-ring with the same energy and length. In this case, luminosity of order 1034cm−2s−1 can be …

Detecting Edges Of Geologic Sources From Gravity Or Magnetic Anomalies Through A Novel Algorithm Based On Hyperbolic Tangent Function, Hanbing Ai, Yunus Levent Eki̇nci̇, Ahmad Alvandi, Hazel Deni̇z Toktay, Çağlayan Balkaya, Arka Roy

Turkish Journal of Earth Sciences

Directional derivative-based edge detectors are commonly used to outline the abrupt lateral variations in densities or magnetizations of geologic sources from potential-field datasets. Some subtle traces of faults, lithological contacts, and lineaments can be made more visible on anomaly maps using these algorithms. However, these algorithms generally suffer from common limitations such as blurry edges with low-resolution or faulty boundaries. To minimize these challenges, we proposed a new efficient edge detector that benefits from the hyperbolic tangent function. The performance of this detector was tested on the responses of a synthetic gravity model and Bishop's complex magnetic model. A Gaussian …

Sequence Stratigraphy And Hydrocarbon Potential Of The Paleozoic Successions On The Arabian Platform And Southeast Türkiye, Muhi̇tti̇n Şenalp, Sema Teti̇ker

Turkish Journal of Earth Sciences

In 1989, the first prolific hydrocarbon reservoirs were discovered by Saudi Aramco in the highly porous and permeable friable continental sandstones (Unayzah reservoirs) and shallow marine carbonates (Khuff reservoirs) of the Paleozoic successions in south of Riyadh, Central Arabia. These successions were strongly affected by tectonic movements (Caledonian and Hercynian orogenesis) and Early and Late Paleozoic Gondwana glaciations. Therefore, some sections were fully eroded or significantly reduced in their thickness. The sequence stratigraphic interpretation of the Paleozoic successions helped to understand the depositional environments and regional distribution of the source, reservoir and cap rock facies in an improved palynologic studies. …

Top To Bottom Interactive Velocity Analysis Using Travel-Time Ellipses And First Break Times From Walkaway Vertical Seismic Profiling Data: A Synthetic Study, Cemal Erdemi̇r

Turkish Journal of Earth Sciences

An interactive velocity analysis method is introduced in this paper and its efficacy is tested on various walkaway vertical seismic profile (WVSP) modeled data sets. In WVSP surveys, interval velocity profiles are determined fairly accurately along the VSP borehole using first break travel time picks from the zero-offset VSP (ZVSP) data. However the accuracy of these vertical velocities fade away quickly as the source distance (offset) from the VSP borehole increases due to possible horizontal changes in the geology or dips of the horizons. If the layer boundaries are not known, a simple approach type of ray tracing using horizontally …
