A key principle underlying most turbulence theories is that the mean energy dissipation rate remains finite even as viscosity vanishes: the so-called zeroth law of turbulence. Although this property has been established for hydrodynamic and magnetohydrodynamic (MHD) turbulence, its validity in weakl…

The configuration path integral Monte Carlo (CPIMC) method is employed to perform first-principles simulations of warm dense matter based on atomic orbitals. The system is modeled as an ion sphere with a pointlike nucleus at its center, and the electronic many-body problem is solved using CPIMC with…

A laser induced fluorescence (LIF) scheme is investigated to probe singly ionized iodine ions (I+) in electric propulsion devices. The transition 6sS2o5→6pP35 at 516.261 nm is considered and the theoretical computation of the weights and positions of the hyperfine structure is carried out. First, th…

Metal conductors pulsed with intense electrical current are of fundamental importance to physics and engineering, yet their motion, equation-of-state (EOS), and electrical conductivity during the solid-liquid phase transition are not fully understood. Photon Doppler velocimetry (PDV) measurements of…

In current-driven metal loads, a nonlinear magnetic-diffusion wave carries current and Joule heating inward from the electrical skin-depth layer, coupling the electromagnetic drive to material compression, melting, and expansion. Photon Doppler velocimetry of electrically thick aluminum measures pre…

We report a seeding mechanism for the current filamentation instability that was identified using an experimental platform where a relativistically intense 2-ps (full width at half maximum) long-wavelength infrared pump laser both produces and interacts with a plasma that is overdense to the pump ye…

We develop an analytical theory of coherent (scaled quadratically with the number of particles) radiation and coherent radiation friction in a head-on collision of a dense charged particle bunch with an intense laser pulse. We demonstrate that the low-frequency coherent radiation in the forward and …

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…

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 …
