We investigate the influence of nonlinear gravity corrections, arising from the Eddington-inspired Born-Infeld (EiBI) theory on wave dynamics, stability, and energy transport processes in polytropic, viscous, and turbulent solar plasmas. Analytical and numerical analyses of the Jeans-normalized quad…

In the presence of an external magnetic field with strength exceeding a certain critical threshold, a right circularly polarized (RCP) laser pulse propagates through an otherwise opaque target. This significantly alters the conventional laser-plasma interaction dynamics, giving rise to a set of nove…

Ultraintense laser interactions with near-critical density (NCD) targets have emerged as a promising approach to enhance proton energy and flux. In this study, we used three-dimensional particle-in-cell simulations to investigate proton acceleration by a linearly polarized 100 TW, 40-fs laser beam i…

We investigate the transport behavior of tungsten impurities with finite inertia in drift-wave turbulence using the Hasegawa-Wakatani model. Unlike previous tracer-based models, our simulations reveal a transition to nondiffusive dynamics for a range of charge states. This mechanism offers a turbule…

A model for the collisional stopping of ions on free electrons in warm dense matter is developed and explored. It is based on plasma kinetic theory, but with modifications to address the warm dense matter regime. Specifically, it uses the Boltzmann-Uehling-Uhlenbeck kinetic equation to incorporate e…

The formation processes of highly ionized plasma channels (filaments), with an electron concentration of Ne∼1018–1019cm−3, in a pulsed nanosecond discharge in air at a pressure of 100–760 Torr are investigated. The studies are carried out for millimeter-sized gaps with a point cathode and flat anode…

Nickel-like ions have a metastable level (3d94s D33) that decays exclusively by a magnetic octupole (M3) transition. We earlier have measured the lifetime of this level in isotopically pure Ni-like Xe ions and have shown how hyperfine interaction modifies the lifetime. We now demonstrate how this lo…

We study the transition from classical radiation reaction, described by the Landau-Lifshitz model, to the quantum mechanical regime. The plasma is subject to a circularly polarized field where the self-consistent plasma current is the source of the electromagnetic field through Ampere's law. The rad…

We discuss synchrotron absorption of a short electromagnetic pulse that propagates in a cold magnetized pair plasma. We show that the pulse can be absorbed when ωB/a0<ω<a0ωB, where a0>1 is the strength parameter of the pulse, and ω and ωB, respectively, are the frequency of the wave and the…

The reflection and transmission coefficients of an electromagnetic wave interacting with an inhomogeneous plasma layer produced by multiphoton ionization of an inert gas in a magnetic field are determined. The possibility of terahertz radiation amplification is revealed. If the frequency of the prob…

We present the results of the molecular dynamics simulation of ultracold Xe plasma in constant homogeneous crossed electric and magnetic fields. A Simulation shows that there are two electron loss mechanisms. The first one is that the initial electron cloud splits into two lobes. The second one is t…

Thermalization times of light ions in fusion plasmas are calculated using quantum and semiclassical dielectric models for the interaction of external particles with plasma electrons and ions. An accurate analytical approximation is obtained, which combines a classical Bohr-type description for the i…

Scale invariance is a hallmark of many natural systems, including solar flares, where energy release spans a vast range of scales. Recent computational advances, at the level of both algorithmics and hardware, have enabled high-resolution magnetohydrodynamical (MHD) simulations to span multiple scal…

The generation of 200 MeV class protons by irradiating a 25 J laser pulse onto a water target using three-dimensional particle-in-cell simulation is shown. Two types of targets—foil and disk—are evaluated and compared. Disks, which are mass-limited targets, produce ions with higher energy than those…

Fully kinetic simulations are used in this work to study strong shock waves in fully ionized plasmas for charge state Z ranging from 1 to 18. The ion stress tensor amplitude agrees well with classical predictions within the compression layer; however, its spatial structure is noticeably shaped by no…
