Scientific Interests and Research Areas:

  • Ion and ion-cluster beams stopping in plasmas
  • Transport phenomena in a magnetized plasma
  • Scattering and transformation of intense electromagnetic waves in plasmas
  • Interaction of charged particles beams with a solid surface
  • Generation of electromagnetic wake-fields by intense laser pulses and charged particle beams in plasmas
  • Microfield fluctuations and radiative transitions in a strongly coupled two-component plasmas

In particular:
Theoretical investigations on the dynamical and transport properties of strongly coupled Coulomb systems (dense plasma, ion beams in storage rings, ions in traps) substantially assisted by applying numerical approaches like molecular dynamics (MD), particle-in-cell (PIC) and classical trajectory Monte Carlo (CTMC) computer simulations. Some particular topics are:

  • Energy loss of heavy ions in a plasma (nonlinear heavy ion stopping), cluster-ion-beam stopping in plasma (correlation effects, Coulomb explosion)
  • Ion stopping and transport in magnetized plasma, Antiproton and ion cooling by electrons and positrons in traps, electron cooling in heavy ion storage rings
  • Dynamic properties of strongly coupled Coulomb systems, Correlation and response functions of nonideal plasmas, In particular the dynamic structure factor and the conductivity of two-component plasmas.
