Electric Microfield Distribution in Charged Fluids: Plasmas, Ionic and Dipolar Mixtures

摘要

The electric microfield distribution in fluids of particles of arbitrary size, shape, charge and charge distribution is studied. The Morita-Iglesias formalism is extended to include angular dependent interactions. The results of the mean spherical approximation are discussed using an exact relation for the second moment of the microfield distribution, obtained in this work. In the Onsagerian strong coupling limit the sum rule for the second moment simplifies, and becomes identical to the mean spherical approximation result for the second moment.
