This paper presents an experimental investigation of magnetic reconnection between two laser-produced expanding plasmas, focusing on the quantitative evaluation of the reconnection rate and energy conversion under varying initial conditions. By changing the separation distance between the drive lase…

Equations describing evolution of the velocity of a rarefied ion beam in a plasma with ion-acoustic turbulence are derived and solved. An ion beam with velocity u greater than the sound speed vs decelerates due to Cherenkov radiation of ion-acoustic waves. Conversely, a beam with u<vs accelerates…

This paper proposes an optimal control strategy to cool an antiproton plasma in a time much shorter than that required by an adiabatic process. The authors examine the length and stability of the plasma, in addition to its duration. The work suggests that optimal control techniques may be useful for experiments with plasmas, in particular with antimatter plasmas, which need to be confined and cooled before significant losses and annihilation occur.

A dusty plasma cloud hosting a counter-rotating vortex lobe pair is driven through controlled neutral-gas pressure ramps spanning nearly an order of magnitude in rate. The transient response is characterized by the longitudinal transport exponents αL and αR, extracted from mean-squared displacements…

We investigate dust-acoustic rogue waves in a one-dimensional binary dusty plasma using analytical nonlinear Schrödinger equation theory and fully kinetic particle-in-cell simulations. Modulational instability initially drives nonlinear focusing and rogue-wave formation, consistent with fluid predic…

Laser wakefield acceleration (LWFA) provides a compact platform for generating bright, ultrashort, and tunable x-ray betatron radiation. When the betatron oscillation wavelength matches the laser centroid oscillation period in a preformed plasma channel, resonance occurs, leading to a rapid amplific…

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 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 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.

Plasma spectroscopy is a fundamental tool for diagnosing laboratory and astrophysical plasmas.

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.…
