Dynamic Local Field, Sum Rules, and Dynamic Structure Factor of a Classified Plasma with a Logarithmic Potential in Two Dimensions at Lambda = 2.

摘要

For a classical one-component plasma gas with a logarithmic potential in two dimensions at Gamma = e-sq/(k sub B) T = 2, we have constructed a dynamic local-field term which satisfies the third-moment and compressibility sum rules exactly. Using it, we have obtained the dynamic structure factor, the plasmon dispersion relation, and the static structure sum rule. The asymptotic behavior of the dynamic local field is compared with the well-known relations due to Niklasson and Shaw. Reprints. (jhd)
