Solitary phase-space holes in pair plasmas

We present theoretical and computer simulation studies of the formation and dynamics of solitary phase-space holes in pair plasmas, which can be applied to both electron-positron plasmas and to plasmas containing positively and negatively charged macroions or macroparticulates (charged dust grains). We apply our numerical treatment to the parameters used in a recent series of experiments in a pair ion plasma whose constituents are negatively and positively charged fullerene carbon nanotubes. New experiments should be conducted to confirm our theoretical and numerical predictions.
