Resonances play a crucial role in media sustaining oscillatory phenomena, such as plasmas. We show with experimental results and numerical simulations that the wakefields driven by individual successive bunches in overdense plasma superpose linearly, and that their amplitude increases along the trai…

A unique coherent bremsstrahlung (CB) regime is proposed for the generation of an isolated half-cycle attosecond pulse (AP), even for the case of a multicycle driving laser pulse, which is realized by the laser pulse interacting with the double-foil target. When the rising edge of the laser pulse in…

This work investigates the unidirectional transport of charged particles across magnetic field lines driven by magnetosonic solitons in a collisionless plasma. Within the framework of a magnetohydrodynamic model, numerical solutions as well as analytical expressions for small-amplitude solitons are …

Experimental and numerical investigations into the generation of strong magnetic fields in plasma, using a picosecond petawatt laser interacting with specially designed “snail” targets, open paths to the creation of all-optical ultrabright sources of directed high-energy charged particle beams.

A very basic aspect in the interaction of ions with plasmas is the effect of screening of the ion charge. In the case of classical plasmas this effect is usually described by linear theories. However, for dense quantum plasmas, deviations from the linear models arise and new effects appear. These no…

This study investigates electron kinetics in a direct current magnetron sputtering discharge, advocating for the use of the cumulative distribution function (CDF) as a superior alternative to conventional probability distribution functions (PDFs), such as the electron energy distribution function.

Following a general heuristic approach, algebraic constraints are established between the parallel and perpendicular power-law exponents of nonaxisymmetric, highly aligned magnetohydrodynamic turbulence, both with and without a strong imbalance between the Elsässer variables. Such relations are univ…

An ultraintense, isolated circularly polarized (CP) attosecond x-ray pulse is often required for many application of pump-probe techniques. A quantum electrodynamics (QED) effect dominated coherent synchrotron emission (CSE) regime is proposed for the generation of an ultraintense isolated, nearly C…

The steadily moving charged object (obstacle) induced modulated electrostatic ion cyclotron (EIC) wave dynamics is modeled through a forced nonlinear Schrödinger equation in collisionless and homogeneous plasmas. The disturbance created by the moving obstacle acts as the source of free energy and is…

Isolated micro-targets are a promising avenue to high-performance laser-driven proton and ion accelerators due to their ability to confine the coupled laser energy to a small volume and small number of particles. Experimental results on proton emission from levitated plastic micro-spheres with an in…

We report in this work the current filamentation instability of laser-produced proton beams in a regime where the plasma collision frequency is much smaller than the plasma oscillation frequency but larger than the growth rate of the instability. In this regime, the plasma electron temperature incre…

Spherically averaged periodic pair potentials offer the enticing promise to provide accurate results at a drastically reduced computational cost compared to the traditional Ewald sum. In this work, we employ the pair potential by Yakub and Ronchi [J. Chem. Phys. 119, 11556 (2003)] in ab initio path …

A primary technical challenge for harnessing fusion energy is to control and extract energy from a nonthermal distribution of charged particles. The fact that phase space evolves by symplectomorphisms fundamentally limits how a distribution may be manipulated. While the constraint of phase-space vol…

Absolute growth of stimulated Raman side scattering (SRSS) in inertial confinement fusion appears to be absent in experiments. Based on simulations the authors find that absolute growth of SRSS occurs only in the limit of an infinite laser beam width. This finding may have implications for the design of experiments.

Langevin dynamical simulations are performed to investigate the depinning dynamics of a two-dimensional (2D) solid dusty plasma, which is modulated by one-dimensional (1D) nonlinear deformed periodic substrates, and also driven by the combination of the DC and AC forces. As the DC driving force incr…

An extension of Maxwell's original prescription for an ideal gas is adopted to derive a broad class of kappa-type velocity distributions, encompassing both fat and short-tailed forms. Within this general framework, a physically consistent fat-tailed kappa distribution is identified that accurately f…

The separation of matter and antimatter in a plasma can be driven by the growth of the Weibel instability. The authors show this effect in a plasma of protons and antiprotons with a relativistic stream of electrons and positrons, by means of particle-in-cell simulations supported by analytical considerations.

Laboratory plasma production almost always preferentially heats either the ions or electrons, leading to a two-temperature state. In this state, density functional theory molecular dynamic simulation is the state of the art for modeling bulk material properties. We construct a statistical mechanics …
