We present an analytical 1D axisymmetric model describing the evolution of the dynamic Z pinch. This model is capable of predicting the trajectories of the imploding sheath's magnetic piston and preceding shock front, along with the velocity, pressure, density, and magnetic field profiles, for any t…

This study uses three-dimensional particle-in-cell simulations to investigate the nonlinear evolution of electromagnetic waves propagating perpendicular to an external magnetic field in a magnetized plasma, with an emphasis on wave breaking and electron energization. In the weakly nonlinear regime (…

Energy injection and dissipation in nonequilibrium systems typically lock microscopic motion and collective flow into a coupled evolution. Our observations in electron-beam-driven dusty plasma reveal a distinct “kinetic decoupling” regime where this synchrony breaks down. While microscopic and colle…

This Letter uncovers five distinct charge transport modes and their transitions in dual-energy electron beam diodes. We via first-principle particle-in-cell (PIC) simulations establish that the specific mode (e.g., space-charge oscillations) and the current transmitted characteristics are essentiall…

The Jeans instability is a fundamental mechanism driving the gravitational collapse and subsequent structure formation in diverse self-gravitating astrophysical environments. We present comprehensive numerical fluid simulations of the Jeans instability in a three component dusty plasma system. The h…

Low-density foams are of significant interest in inertial confinement fusion (ICF), with potential applications as fuel carriers, ablation layers, or as a hohlraum filling material. Despite their potential, the shock response of these materials remains poorly characterized, limiting the accuracy of …

High-accuracy modeling of laser-plasma interactions at high intensity requires precise knowledge of the laser field, including its asymmetries. However, the experimental characterization of such lasers is often limited to fluence measurements in transverse planes, which creates the need for a reliab…

We introduce a simple symmetric Hamiltonian map that models the magnetic field lines of a double-null diverted tokamak and compare its behavior with the corresponding symmetric single-null map. The phase-space structure of both models is characterized using the finite-time Lyapunov exponent and the …

Based on the data recorded during the Parker Solar Probe mission, it can be suggested that there is no balance between kinetic and magnetic energy in the vicinity of the Sun. The spectra collected at different radial distances show an energy transfer from one component to another, followed by a chan…

A wide variety of spectroscopic methods are used for the diagnostics of laser-produced plasma. One particularly powerful diagnostic is high-resolution emission line spectroscopy, in conjunction with atomic calculations and radiation hydrodynamic simulations. In this work, we present line-resolved sp…

In indirect-drive inertial confinement fusion (ICF), a hohlraum serves the purpose of converting laser energy into thermal x-ray energy. This process involves the interaction of low-density ablated plasmas, which can give rise to weakly collisional shocks characterized by the Knudsen number Kn on th…

Physical models aimed to reproduce basic features of the solar sunspot cycle are typically based on the solar dynamo mechanism. Usually qualitative arguments are used to define parameters of the model, among which a challenging component is the nonlinear form of quenching of the α effect governing r…
