SUMMARY:High energy density plasma simulations using ultracold neutral
  plasmas\, JIMFEST 2018\, Scott Bergeson\, Brigham Young University
DESCRIPTION:Strongly-coupled Coulomb systems are typically fluid-like 
 plasmas characterized by the ratio of the nearest-neighbor electrical 
 potential energy to the average kinetic energy. When this ratio is nea
 r unity\, the plasmas are non-ideal and the foundational assumptions o
 f plasma physics are no longer valid. Astronomical examples include th
 e crusts of white dwarf stars\, the interior of Jovian planets\, and t
 he dust belts of Saturn. Laboratory examples include laser-driven comp
 ression shocks\, exploding wires\, inertially confined plasmas\, and\,
  surprisingly\, photo-ionized laser-cooled atoms. Transport properties
  in these widely disparate plasmas scale with the ratio of potential-t
 o-kinetic energy (the Coulomb coupling parameter). Even systems that a
 re widely disparate in temperature and density can be thermodynamicall
 y similar if this ratio is the same. I'll talk about our work in photo
 -ionized laser-cooled atoms\, presenting progress in thermalization\, 
 transport\, and equilibration.
