Plasma supports collective modes and particle–wave interactions that lead to complex behaviour in, for example, inertial fusion energy applications. While plasma can sometimes be modelled as a charged fluid, kinetic description is often crucial studying nonlinear effects in the higher-dimensional momentum–position phase space describes full complexity of dynamics. We create differentiable solve...

The nonlinear three-wave interaction process at the heart of the parametric decay process is studied by launching counter-propagating Alfv en waves from antennas placed at either end of the Large Plasma Device [W. Gekelman et al., Rev. Sci. Instrum. 62, 2875 (1991)]. A resonance in the beat wave response produced by the two launched Alfv en waves is observed and is identified as a damped ion ac...

We predict the existence of gap solitons in a nonlinear, quadratic Fabry-Pérot negative index cavity. A peculiarity of a single negative index layer is that if magnetic and electric plasma frequencies are different it forms a photonic band structure similar to that of a multilayer stack composed of ordinary, positive index materials. This similarity also results in comparable field localization...

We investigate an efficient mechanism for generating magnetic fields in turbulent, collisionless plasmas. By using fully kinetic, particle-in-cell simulations of initially non-magnetized plasma, we inspect the genesis magnetization, a nonlinear regime. The complex motion is initiated via Taylor-Green vortex, and plasma locally develops strong electron temperature anisotropy, due to strain tenso...

Air plasma spray (APS) process is used to produce high density and flowability spherical powders. Phase transformation that occurred in this process isn’t well known. In this paper, the YSZ powders have been sprayed in water to investigate the morphology changes and phase transformations via air plasma spray (APS) method. Phase analysis of powders was examined by XRD and the crystallite size an...

Adjustment of phenytoin dosage in patients is very difficult due to its nonlinear metabolism and patient to patient variation in its kinetics. It has been recommended that the dosage of phenytoin should be adjusted according to its plasma concentration and requirements of the patients. Therefore, the present study was carried out to identify the various factors which may influence the plas...
