We investigate with particle-in-cell simulation the transport of fast electrons of MeV under a kT-level magnetic field produced by a circular coil target, where the fast electrons are generated by a picosecond laser pulse with typical intensity of 5×1019W/cm2 adopted in fast ignition. The fast elect…

Inertial confinement of fusion plasmas can be realized using the dynamic Z pinch, an electromagnetically driven cylindrical implosion system that is also used to generate intense x rays. However, the Z pinch is subject to magnetic Rayleigh-Taylor (MRT) instability, which must be suppressed for pract…

We compare model solutions of a forced Kadomtsev-Petviashvili (fKP) equation with experimental observations of dust acoustic precursor solitons excited by a supersonically moving charged cylindrical object in a dusty plasma medium. The fKP equation is derived from a three-fluid-Poisson model of the …

We consider the problem of optimizing a set of passive superconducting coils (PSCs) with currents induced by a background magnetic field rather than power supplies. In the nuclear fusion literature, such coils have been proposed to partially produce the 3D magnetic fields for stellarators and provid…

Recent experimental demonstrations of ignition and target gain in inertial confinement fusion (ICF) have stimulated interest in exploring the fundamental physics of violent deuterium-tritium (DT) burn in high-gain ICF targets. A significant DT-burn fraction is a necessary condition for high energy g…

Ion fast ignition by laser-driven ion beams is an interesting approach within the inertial confinement fusion scheme to achieve nuclear fusion. In the ion fast ignition, once the precompression of the target is finished, a sphere of fully ionized deuterium-tritium (DT) is obtained. In this work, we …

Using a wave-number-advection algorithm, we describe a method to add global profile curvature terms to the local gyrokinetic equations. This approach enables a high-precision global simulation capability without sacrificing the efficiency and spectral accuracy of local simulations. Preliminary numer…

For many purposes, classical plasma dynamics models can work surprisingly well, even for strong electromagnetic fields, approaching the Schwinger critical fields, and high frequencies, approaching the Compton frequency. However, the applicability of classical models tends to depend rather sensitivel…

We conducted a numerical study of the effects of the modulation amplitude and period of a temporally modulated laser pulse on instabilities at an ablation front. The physical features of the oscillatory acceleration and ablation velocity in unperturbed ablative flows display periodic oscillations. A…

Mixed-mode oscillation (MMO) is a type of complex dynamic behavior commonly seen in multitimescale dynamical systems. As a typical nonlinear medium, MMOs have been experimentally observed in a variety of plasma systems. However, the underlying microscopic physical mechanisms that are responsible for…

Density-functional-theory-based molecular dynamics simulations (DFT-MD) are a very successful tool to calculate the electrical conductivity of materials in the region of warm and dense matter. However, it requires a correction to implement the contribution of electron-electron collisions in the low-…

Radiative shocks are shock waves where radiation plays a crucial role in shaping their dynamics and structure. This study investigates the influence of advanced radiation modeling, using the M1-multigroup moment method, on the properties of radiative shocks. We identify three key effects: the shock …

We have performed experiments on dusty plasmas under the weightlessness conditions of parabolic flights where the dust particles form an extended homogeneous dust cloud. The three-dimensional (3D) dynamic state of the dust cloud is characterized. Therefore, the particle trajectories have been record…

In this paper, the first in a series, we present a new theoretical model for the global structure and dissipation of relativistically magnetized collisionless shock waves. Quite remarkably, we find that in contrast to unmagnetized shocks, the leading energy dissipation channel does not involve colle…

Self-similarity is a property of an object or process wherein a part is similar to the whole. Mathematically, it can often be expressed as a power-law scaling of the quantity of interest. Extended self-similarity is a concept widely used in the field of turbulence and refers to the power-law scaling…

We extract electron transport properties from atomistic simulations of a two-component plasma by mapping the long-wavelength behavior to a two-fluid model. The mapping procedure is performed via Markov Chain Monte Carlo sampling over multiple spectra simultaneously. The free-electron dynamic structu…

Ultrashort pulsed lasers can produce thin columns of plasma in the air via femtosecond filamentation, and these plasmas have been found to generate broadband terahertz and radio frequency (RF) radiation. A recent theory argues that the currents driven at the boundary of the plasma excite a surface p…
