We have solved the Schrödinger equation for Varshni plus Woods-Saxon potential in N-dimensions within the framework of Nikiforov-Uvarov method by using Greene-Aldrich approximation scheme to the centrifugal barrier term. We obtained the numerical bound state energies for both physical parameters and some diatomic molecules for various values of screening parameter which characterizes the strength of […]
We investigate the asymptotic behavior of the solutions to the Klein-Gordon and Dirac equations using the local spatial averaging approach to Bohr’s correspondence principle in the large principal quantum number regime. The procedure is applied in two basic problems in $1+1$-dimensions, the relativistic quantum oscillator and the relativistic particle in a box. In the harmonic […]
In this study, a 2 kJ plasma focus device of Mather type was employed to grow Copper Oxide (CuO) thin film at room temperature on the glass substrate. The anode of the device was made of Copper alloys. A mixture of oxygen and argon (O2+ Ar) gases was used as the working gas for CuO […]
In the present study, the microwave resonant plasma source has been designed to provide the ionosphere like condition inside the Iranian Space Plasma Simulation Chamber (ISPSC). This chamber contains plasma with electron density of 1×105 −1×1010 cm−3 and temperature of 1-5 eV. In order to reach these plasma parameters inside the ISPSC, the plasma source […]
In this study, we determine the effective permittivity of a medium in which spherical inclusions are embedded in a host medium whose permittivity is given by ε_h. It is interesting to note that the inclusions are made up of graphite and their basal planes are oriented in two configurations, 1) parallel and, 2) perpendicular to […]
In this paper, a set of two-fluids equations based on the quantum magnetic hydrodynamic model (QMHD) for electron-positron plasma were considered and the role of spin in different spin-spin, and spin-field interactions were briefly discussed. Furthermore, effects of density and heterogeneity in the equations were considered. For each of the two electron and positron fluids, […]
The pondermotive force causes interesting nonlinear processes in the interaction of the intense laser beam with plasma. The pondermotive effect modifies the profile density, and in turn, affects the propagation of the laser beam through the plasma medium. Here, it is considered the inhomogeneous collisional plasma, and assumed that a high-intensity laser beam passes through […]
In the fractional nonrelativistic potential model, the decomposition of heavy quarkonium in a hot magnetized medium is investigated. The analytical solution of the fractional radial Schrödinger equation for the hot-magnetized interaction potential is displayed by using the conformable fractional Nikiforov-Uvarov method. Analytical expressions for the energy eigenvalues and the radial wave function are obtained for […]
AbstractThe doping of Pb2SeTaO6 with Ge ferroelectrics was produced by a high-temperature solution method. We measure dielectric constant, dielectric loss and conductivity in the temperature range −30°C to 200°C and frequency range 1 to 100 KHz. The value of dielectric constant of the Pb2SeTaO6 (PST) crystal remained the same after thermal annealing whereas they decreased […]
Impacts of the liquid environment on the characteristics of pulsed laser ablation (PLA) synthesized tungsten (W) nanostructures have been investigated. High purity W target was irradiated by the fundamental wavelength of a Q-switched Nd:YAG laser of 7 ns pulse width and 1 J/cm2 laser fluence in different liquid environments including distilled water, ethanol, acetone, and […]
