Finite systems

One speciality of complex plasmas is that it is possible to study small bounded systems of a few particles only. Further these systems can be studied with 1D, 2D, and 3D geometry. In the frame work of the SFB TR24 Fundamentals of Complex Plasmas  we have studied in close collaboration together with the groups of Prof. Melzer and Prof. Bonitz finite 3D systems, the so called Yukawa balls. We were able to understand their fundamental construction principle als well as to study their dynamical and even thermodynamical properties. 

  • Structure  (shells, parabolic density profile, meta stable configurations)
  • Dynamics (Normal modes, shear stability)
  • Thermodynamics (phase transitions, melting point)
