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…

There is an ongoing interest in using spectroscopy in inertial confinement fusion (ICF) experiments, where dopants such as krypton can provide vital information about the temperature and density of the imploding plasma. While the most advanced tools for calculating Stark profiles are computer simula…

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.

Collisional dissipation is expected to be the primary damping mechanism for helicon waves in low-temperature, high-density, moderate magnetic field plasmas. Combining a normal-mode analysis with high-resolution magnetic field measurements, we validate this expectation across a broad parameter space.…

In this paper, we address the problem of wave propagation within an unbounded time-modulated magnetized plasma in a Faraday configuration. We present an analysis formulated by coupling Maxwell's equations with the hydrodynamic evolution equation for the plasma current density, and casting the result…

In plasmas, a Langmuir wave is a bridge connecting external sources with waves or particles, whose properties are mainly determined by the shape, amplitude, dispersion relation, or phase of the Langmuir wave. Here we propose a scheme to generate coherent Langmuir wave trains with width as short as s…

The dissipation mechanisms in weakly collisional turbulent plasmas have been a longstanding topic of investigation. In recent years, one significant and promising development has been the use of the “scale-filtered” Vlasov-Maxwell equations to fully quantify the scale-by-scale energy balance, a feat…

In a series of magnetized-liner-inertial-fusion experiments performed at the Z pulsed power facility of Sandia National Laboratories, beryllium liners filled with deuterium gas densities between 0.7 to 1.4 mg/cc and a tracer amount of krypton were imploded. At the collapse of the cylindrical implosi…

Radiofrequency-heated, high-β, magnetized hydrogen plasmas in the Princeton field-reversed-configuration-2 device, with its magnetic-field-parallel radial boundary formed by eight discrete room-temperature coaxial copper rings, display constant density for times exceeding 150 ms.

Progress towards achieving net gain from nuclear fusion is typically characterized by the triple product nTτ.
