Query: Highly Charged Ions in a Dilute Plasma: An Exact Asymptotic Solution
  Involving Strong Coupling   The ion sphere model introduced long ago by Salpeter is placed in a rigorous
theoretical setting. The leading corrections to this model for very highly
charged but dilute ions in thermal equilibrium with a weakly coupled,
one-component background plasma are explicitly computed, and the subleading
corrections shown to be negligibly small. This is done using effective field
theory methods advocated by Brown and Yaffe. Thus, corrections to nuclear
reaction rates that such highly charged ions may undergo can be computed
precisely. Moreover, their contribution to the equation of state can also be
computed with precision. Such analytic results for very strong coupling are
rarely available, and they can serve as benchmarks for testing computer models
in this limit.
