Contribution

It generalizes the dust approach to quantum systems, allowing detailed simulation of ion dynamics with quantum electron effects included.

Findings

Inclusion of electron dynamics and wake effects in ion behavior.

Extension of the Mermin formula for quantum screening.

Ability to simulate magnetized electron effects.

Abstract

A scheme which allows to compute the dynamics of strongly correlated classical ions embedded into a partiallzy ionized quantum plasma by first principles molecular dynamics is presented. The dynamically screened dust approach of Joyce and Lampe [Phys. Rev. Lett. {\bf 88}, 095006 (2002] ist generalized to quantum systems. The electrons are treated fully quantum-mechanically taking into account their dynamical screening of the ion-ion interaction in linear response on the basis of an extended Mermin formula. The scheme allows to include the effect of the electron dynamics, electron streaming, wake effects and electron magnetization.
