We investigate linear perturbations of an incompressible, weakly collisional, anisotropic plasma in the low frequency limit using an extended 16-moment fluid description that retains parallel and perpendicular heat fluxes. We identify a class of linear perturbations associated with a conserved therm…

When a high-power, femtosecond, circularly polarized (CP) laser pulse impinges on a micrometer-scale aperture in a solid foil target, it drives surface plasma oscillation on the boundary, and generates high-order harmonic vortices in the diffracted light [L. Yi, Phys. Rev. Lett. 126, 134801 (2021).]…

Plasma spectroscopy is a fundamental tool for diagnosing laboratory and astrophysical plasmas. Accurate interpretation of spectra depends upon precise modeling and comprehension of Stark broadening and other mechanisms affecting spectral lines. In this context, computer simulations have emerged as v…

We present calculations of diffusion coefficients in grain boundaries (GBs) in Yukawa crystals for astrophysics. Our methods follow from our recent work calculating diffusion coefficients in perfect body-centered cubic crystals. These diffusion coefficients show only a weak dependence on the crystal…

The authors demonstrate fusion ignition in a hohlraum modified with diagnostic windows that burn through prior to ignition. This provides a platform for laboratory-astrophysics experiments previously inaccessible. The x-ray flux escaping the holraum during and after ignition is the brightest radiation source available in the laboratory.

Instabilities are a common occurrence in plasma discharges where they play an important role in system behavior and performance. While such instabilities are typically in the kHz and MHz range, this work reports a low frequency (∼100Hz) instability observed in supersonic inductively coupled plasmas.…

Finding feasible coils for stellarator fusion devices is a critical challenge of realizing this concept for future power plants. Current design efforts struggle to navigate the highly nonconvex optimization landscape, spend considerable resources scanning the parameter space, and may produce subopti…

An important process for antimatter experiments is the cooling of particles in a Penning-Malmberg trap to experimentally useful temperatures. A non-neutral plasma of one species (e.g., antiprotons) can be collisionally cooled on another colder species (e.g., electrons). Modeling temperature relaxati…

We performed numerical simulations of two-dimensional magnetohydrodynamic (2D MHD) turbulence on an 81922 grid with mean magnetic fields B0=0,1, 3, 6, and 10. The energy spectra and fluxes of Elsässer variables are in better agreement with Kolmogorov-like phenomenology (k−5/3) than Iroshnikov-Kraich…

Placed in the context of the pursuit of monoenergetic proton beams accelerated by lasers, this work explains the fact that they are not observed in experiments. The authors show that this is due to the to the transverse inhomogeneity of the laser and that this can be overcome with flat top laser profiles.

Magnetars are young, isolated neutron stars that possess an exceptionally strong magnetic field, with surface dipolar strengths on the order of 1015G. One of the plausible scenarios for generating such a strong field is an exponential amplification by a turbulent convective dynamo during the protone…

We derive statistical distributions for the degrees of freedom in wave packet molecular dynamics models. Specifically, a theory is developed for the width distributions of Gaussian wave packets in both isotropic and anisotropic formulations. The resulting distribution functions show good agreement w…

This work investigates how locally persistent crystal-like ordering in liquids influences the Debye-Waller factor. We have developed a theoretical framework based on liquid-phonon theory which introduces a phonon relaxation time, expressed as the ratio of shear viscosity to infinite-frequency shear …

The excess energy, entropy, and pressure of a strongly coupled Yukawa fluid are calculated from the variational approach using the fluid of hard spheres as a reference system. As in the case of the one-component plasma, the Percus-Yevick virial entropy is appropriate for such calculations and delive…

The variational approach based on the Bogoliubov inequality using the fluid of hard spheres as a reference system is implemented to evaluate instantaneous shear, bulk, and longitudinal elastic moduli, as well as related sound velocities of Yukawa fluids. The remarkable accuracy of this method is doc…

Electron holes are Debye-scale kinetic structures that mediate particle trapping, field-aligned electric fields, and energy conversion in collisionless plasmas. How such coherent structures interact with one another, however, has remained difficult to resolve in situ. Using four-spacecraft Magnetosp…

While investigating radio-frequency gas breakdown, the authors experimentally observed and simulated a novel, time-dependent striated optical emission structure. The study reveals that these striking patterns are driven by differing electron-ion mobilities and locally amplified ionization, which are ultimately suppressed as the electric field becomes screened.

The Stokes-Einstein (SE) relation links microscopic fluctuations to macroscopic dissipation. Whether it survives in driven-dissipative, strongly coupled systems far from global equilibrium remains an open question. Using a macroscopic dust vortex in a radio-frequency complex plasma, we isolate therm…

The fast ignition paradigm previously developed for inertial confinement fusion is here extended to magnetized linear inertial fusion. The authors’ model showcases fast ignition’s potential to lead to more practical, cost-effective, and engineering-wise viable magnetized linear inertial fusion designs.
