Abstract

Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau or Balescu-Lenard equation. However, these equations do not properly take into account correlation effects which requires to use generalized non-Markovian kinetic equations. While the latter have been successful for lattice models, applications to continuous systems such as plasmas are severely hampered by aliasing effects. Here we present a strategy how to suppress aliasing and make applications of non-Makrovian quantum kinetic equations to plasmas possible.
