The dynamics of strongly coupled plasmas at mK temperatures are studied for the special case of stopping highly charged ions in a laser cooled plasma of N=105 24Mg+ ions [1].
Using a parallel simulation code the stopping process is studied with respect to stopping times, plasma stability and recooling efficency [2]. It is shown that the proposed cooling scheme is feasible for cooling highly charged rare ions to mK temperatures without suffering from ion loss due to charge exchange.
In the outlook we present examples of simulations of strongly coupled plasmas in beam and trap physics illustrating the capabilities of the simulation with regard to investigating many-particle systems at low temperatures.
