We numerically model the ultrarelativistic dynamics of a dense plasma microtarget, in a focus of several intersecting femtosecond laser pulses of multipetawatt power each. The aim is to examine prospective experimental approaches to the search for the Inverse Faraday Effect induced by radiation fric…

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…

Mixtures of bare atomic nuclei on a nearly uniform degenerate electron background are a realistic model of matter in the interior of white dwarfs. Despite tremendous progress in understanding their phase diagrams achieved mainly via first-principle simulations, structural, thermodynamic, and kinetic…

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…

The dynamical interplay between turbulent particle transport (Γ) and Reynolds stress (ℜ) at the edge of toroidal magnetically confined plasmas is experimentally investigated on the basis of the cross-coupling between density and potential fluctuations in drift-wave turbulence. Both Γ and ℜ are found…

High-field terahertz (THz) pulse generation is investigated through the interaction of an intense single-color CO2 laser pulse with helium (He) gas targets. Employing particle-in-cell (PIC) simulations, this study reveals a substantial enhancement in THz generation efficiency, even with a single-col…

A simple nonempirical approximation is proposed to calculate the ionic thermal contribution to the average-atom equations of state. The approximation represents the main regularities of temperature and mass-density dependences of the ionic thermodynamic-function components revealed from the pseudoat…

The long-term development of the transitional regime of drift-wave turbulence is studied in a magnetized plasma column by means of the conditional-average technique. In the transitional regime, small changes in the magnetic-field strength as control parameter lead to large changes in the correlation…

It is shown that the Landau damping of electron plasma waves (EPWs) is significantly enhanced in a transverse magnetic field with tens of teslas due to a strong modification of the electron velocity distribution function formed in the two-plasmon-decay (TPD) process. The Landau damping even in the r…

The dynamics of electrons in space plasmas, such as the earth’s radiation belts, are affected by the presence of wave turbulence, even when a resonance condition is not satisfied. The authors propose an expression to describe this resonance broadening effect, and find that it compares well with test particle simulation results. The study is applied to whistler-mode chorus waves in the radiation belt’s electrons, but can be easily extended to a wide range of systems.
