Modeling of discharge processes in a new type of pulse-plasma ignition systems with a controlled spark gap

The results of computer and physical modeling of discharge processes in a new type of pulse-plasma ignition systems for gas turbine engines with a controlled switching spark gap are presented. A circuit design model of a pulse-plasma ignition system has been developed, which makes it possible to evaluate the patterns of discharge processes in a […]

Rational solutions to the KdV equation from Riemann theta functions

Rational solutions to the KdV are constructed from the finite gap solutions of the KdV equation given in terms of abelian functions. For this we use a previous result giving the connection between Riemann theta functions and Fredholm determinants and also wronskians. By choosing the parameters of these solutions according to a number intended to […]

Electrical and optical parameter-based numerical simulation of high-performance CdTe, CIGS, and CZTS solar cells

The market for thin-film solar cells is gradually increasing and is expected to grow to 27.11 billion dollars by 2030. The most extensively researched thin film technologies based on simulation right now include solar cells made of Cadmium Telluride (CdTe), Copper Indium Gallium Selenide (CIGS), and Copper Zinc Tin Sulfide (CZTS). This work aims to […]

Dielectric, electro-optical and spectroscopic properties of silver doped zinc oxide-ferroelectric liquid crystal composite system

In the present study, silver doped zinc oxide nanoparticles (NPs) have been added in the pristine ferroelectric liquid crystal (FLC). The dielectric, electro-optical and spectroscopic properties was investigated of the pristine FLC and FLC-NPs composite system. The dispersion of NPs into the pristine FLC material sturdily influences the various properties of composite system. Due to […]

Effect of long-rang interactions on the Kosterlitz-Thouless transition

The two-dimensional XY model of continuous spins on a square lattice is studied by Monte Carlo simulations in the nonextensive statistical approach of Tsallis, using the Metropolis algorithm with a transition probability of the nonextensive approach. Energy per spin, magnetization per spin, heat capacity, magnetic susceptibility, Binder cumulant of the magnetization and Binder cumulant of […]

On optical field driven quantum spin Hall phase in Bi_2Se_3 thin film with magnetic Impurities

The normal incidence of circularly polarized optical field (POF) of tunable intensity on the topological insulator Bi2Se3 film is shown to give rise to the quantum spin Hall (QSH) effect, in the presence of the magnetic impurities (MI), starting with a low-energy two-dimensional, time-dependent Hamiltonian in the framework of the Floquet theory. The quantized topological […]

Bohm sheath criterion for electronegative warm plasma carrying seconadary electron emission in an oblique magnetic field

The Bohm sheath criterion is formulated by using Sagdeev potential approach for electronegative warm plasma under oblique magnetic field and secondary electron emission from the wall. In this model the effect of collisions between positive ions and neutral, ionization, electronegativity, non-extensivity and temperature ratio (positive/negative ion to electron) are also considered to get the exact […]

Particle acceleration by three-dimensional asymmetric current sheet

Magnetic reconnection is known as an essential process to convert stored energy of magnetic field into the kinetic, thermal energy of plasma and the acceleration of charged particles in astrophysical and space plasmas. In this paper, we investigate some features of test particle acceleration during spine reconnection with an asymmetric current sheet. To do so, […]

Theoretical modelling of Terahertz acoustic wave generated by a femtosecond laser pulse in a dense plasma having density gradient

Near the critical layer, a p-polarized laser that impinges on a dense plasma having density gradient at an angle to the density gradient transforms into a plasma wave. Even after the laser pulse has stopped, the plasma wave survives. The electrons close to the crucial layer are heated by the plasma wave. Increased plasma pressure […]

Time dependency of the spin-orbit interaction and magnetic field in the long-range Ising model

In this study, we have investigated a two-spin Ising model with added Dzyaloshinskii-Moriya (DM) interaction in an external magnetic field. We have considered two different initial states of the system and surveyed the time evolution of entanglement of the system for different parameters such as exchange coefficient, DM coefficient, and magnetic field. The Ising interaction […]
