Effective Potential Theory: A Practical Way to Extend Plasma Transport Theory to Strong Coupling
The effective potential theory is a physically motivated method for extending
traditional plasma transport theories to stronger coupling. It is practical in
the sense that it is easily incorporated within the framework of the
Chapman-Enskog or Grad methods that are commonly applied in plasma physics and
it is computationally efficient to evaluate. The extension is to treat binary
scatterers as interacting through the potential of mean force, rather than the
bare Coulomb or Debye-screened Coulomb potential. This allows for aspects of
many-body correlations to be included in the transport coefficients. Recent
work has shown that this method accurately extends plasma theory to orders of
magnitude stronger coupling when applied to the classical one-component plasma
model. The present work shows that similar accuracy is realized for the Yukawa
one-component plasma model and it provides a comparison with other approaches.Comment: 6 pages, 3 figures, Proceedings of the Strongly Coupled Coulomb
