Structural characteristics of strongly coupled ions in a dense quantum plasma.

摘要: The structural properties of strongly coupled ions in dense plasmas with moderately to degenerate electrons are investigated the framework one-component plasma model interacting through a screened pair interaction potential. Special focus is put on description electronic screening Singwi-Tosi-Land-Sjolander (STLS) approximation. Different cross-checks and analyses using ion potentials obtained from ground-state quantum Monte Carlo data, random phase approximation (RPA), existing analytical models presented for computation properties, such as distribution static structure factor, ions. results highly sensitive features This effect particularly visible factor. applicability range potential computed STLS identified terms density temperature electrons. It demonstrated that at r_{s}>1, where r_{s} ratio mean interelectronic distance Bohr radius, correlations beyond RPA have nonnegligible properties. Additionally, hypernetted chain calculation analyzed employing effective coupling parameter approach.
