Space-time versus particle-hole symmetry in quantum Enskog equations
Václav Špička, Klaus Morawetz, Pavel Lipavský
The non-local scattering-in and -out integrals of the Enskog equation have reversed displacements of colliding particles reflecting that the -in and -out processes are conjugated b…

Nonlinear relaxation field in charged systems under high electric fields
Klaus Morawetz
The influence of an external electric field on the current in charged systems is investigated. The results from the classical hierarchy of density matrices are compared with the re…

Momentum conservation and local field corrections for the response of interacting Fermi gases
Klaus Morawetz, Uwe Fuhrmann
We reanalyze the recently derived response function for interacting systems in relaxation time approximation respecting density, momentum and energy conservation. We find that mome…
