Wave-vector and frequency dependent complex dielectric function and related physical properties of a weakly coupled one dimensional two component hot plasma

摘要

The complex dielectric function has been obtained for one dimensional two component weakly coupled classical and quantum hot plasmas in the entire wave-vector and frequency range. The related physical properties: dynamical structure factor and its singularities which yield collective modes, reflectivity of low energy photons and static pair correlation function about an impurity, positron, introduced in the plasma, have been computed and compared with the corresponding quantities in one component plasma. The results for the two plasmas are found to be markedly different.
