      Starting from the exact microscopic equations for an unmagnetized dusty plasma, where the dust charge is regarded as a new degree of freedom of the system, we present a self-consistent set of equations that is suitable for ...

    • Weak turbulence theory for collisional plasmas 

      Yoon, Peter H.; Ziebell, Luiz Fernando; Kontar, Eduard; Schlickeiser, Reinhard (2016) [Artigo de periódico]
      Plasma is an ionized gas inwhich the collective behavior dominates over the individual particle interactions. For this reason, plasma is often treated as collisionless or collision-free. However, the discrete nature of the ...
