46th International Workshop on High Energy Density Physics with Intense Ion and Laser Beams

Foam-based targets are appealing for driving high-efficiency radiation-matter coupling in high-energy-density and high-intensity physics experiments [1-4]. In particular, low-density foams enable the generation of a near-critical plasma in which laser pulses with relativistic field strength, $a_0$ ≫ 1, propagate. In this plasma, the laser delivers its energy to a large number of electrons and...

Highly ordered nanowire arrays with sub-wavelength diameter can be engineered to absorb multi-PW laser pulses with ultra-high-contrast (<10$^{-12}$ on ps timescales), sub-100-fs pulse duration at intensities above 10$^{20}$ W/cm$^2$ with efficiency nearing 100%. A large fraction of the absorbed energy is converted to high-current ion and electron flows in a controlled manner by this Nano...

We present a novel, more general analytic solution for the moments of the Boltzmann collision operator. Such moments are essential for deriving hydro equations and their nonthermal extensions. To the best of our knowledge, they have so far only been evaluated for specific models, cross-sections, small nonthermal contributions, and small relative velocities. We overcome these limitations by...

A brief description of the five moment model of Hydrodynamics for Coulomb collisions is given. The model includes large angle collisions. The corresponding integrals are evaluated to logarithmic and constant order in the maximum impact parameter. The Bethe formula is recovered in the appropriate limit.
This model is then self-consistently coupled to a deuterium-tritium plasma of a given...

We derive a generalized Beth-Uhlenbeck formula for the entropy as well as the density, of a dense fermion system with strong two-particle correlations, including scattering states and bound states. We work within the $\Phi-$derivable approach to the thermodynamic potential. The formula takes the form of an energy-momentum integral over a statistical distribution function times a unique...
