Entanglement from Quantization-Deformation

In this paper, the unitary solutions of the Quantum Yang–Baxter Equation derived via the quantization-deformation of a Poisson Lie group associated to an r-matrix (solution of a classical Yang-Baxter equation) are introduced. The solutions of the algebraic and braided Quantum Yang-Baxter equations that are explored contain a deformation parameter, and will be used to perform quantum entanglement when acting on bipartite quantum states.

Various Properties of Heavy Quarkonia from Flavor-Independent Coulomb Plus Quadratic Potential

We examine heavy quarkonia ( and ƀ) characteristic properties in the general framework of non-relativistic potential model consisting of a Coulomb plus quadratic potential. The potential parameters are determined by simultaneous fit of the  states of both   and ƀ some known experimental values and with the help of Virial theorem, so that the potential is flavor-independent. The obtained results are compared with the corresponding results from Cornell potential and with the available experimental data. The overall agreement with the experimental data is quite good, particularly for the mass spectra.

Growth and Optical Characteristics of Jordanian Silica Sand Thin Films

High-purity Jordanian silica sand (J-SiO2) thin films have been grown by RF-reactive magnetron sputtering on crystalline Si (100) and quartz substrates at temperature T < 52o C. From the X-ray diffraction observations, it was found that all films have an amorphous nature. The chemical states of oxygen and silicon in the SiO2 thin films were also investigated by energy-dispersive X-ray (EDX) spectroscopy. The EDX analysis revealed that the films have a nearly stoichiometric composition (Si/O, 73.42%/25.83%). The surface morphology of the as-deposited films was studied using field emission scanning electron microscopy.  ...

Bulk Etch Rate of CR-39 Track Detector Exposed to Gamma Dose Using D-Le Method

The use of solid state track detectors (SSNTDs) has already become well-known, having been extensively used in nuclear physics, space physics, biophysics, geology, nuclear engineering, monitoring radon concentrations of radon gas by recording its emitted alpha particles, as well as in many other fields. It is known that some plastic types of solid state nuclear detectors such as polycarbonate CR-39 and PM-355, cellulose nitrate CN-85 and LR-355 or cellulose acetate CA-80 are highly sensitive to ionizing radiations and charged particles. ...

Determination of Radon, Uranium and Other Radioactive Isotopes’ Concentration in Different Types of Natural Water in Nenava Governorate

Radon (222Rn) is a naturally occurring radioactive gas with a half-life of 3.82 days, released from the normal decay of the elements uranium, thorium and radium in rocks and soil. It is an invisible, colourless, odourless and chemically inert gas and has no taste. Radon is fairly soluble in water and organic solvents and seeps up through the ground and diffuses into the air. It dissolves into ground water and surface water and can be released into the air when water is used. Radon is also present outdoors and indoors, but it is normally found at very low levels in outdoor air and in water from rivers and lakes. ...
