White dwarfs are a class of stars with unique physical properties. They present many
challenging problems whose solution requires advanced theories of dense matter, state-of …

Spectral line-shape models are an important part of understanding high-energy-density
(HED) plasmas. Models are needed for calculating opacity of materials and can serve as …

Short-pulse, laser-solid interactions provide a unique platform for studying complex high-
energy-density matter. We present the first demonstration of solid-density, micron-scale keV …

High-intensity, short-pulse lasers are crucial for generating energetic electrons that produce
high-energy-density (HED) states in matter, offering potential applications in igniting dense …

X-ray line emission spectra can thoroughly characterize hot plasmas, especially when line
shapes and ratios convey distinct aspects of plasma conditions. However, the high spectral …

Spectral-line-broadening models have been moving towards including full Coulomb
interactions between the atom and plasma, replacing the commonly used dipole …

In this article, a fully relativistic approach is proposed to precisely predict the electronic
structures, spectral properties, cross sections, and degrees of linear polarization of light …

High repetition rate laser systems enable new strategies for diagnosing plasma behavior
with large datasets. Here, we define an ensemble technique that relies on randomized …

A high-resolution x-ray spectrometer was coupled with an ultrafast x-ray streak camera to
produce time-resolved line shape spectra measured from hot, solid-density plasmas. A …

We demonstrate a flexible multichannel fiber-based imaging Doppler spectrometer to
characterize plasmas in high intensity (≥ 1× 10 18 W/cm 2) laser-plasma experiments at …
