## Abstract The numerical solution of the quantum Landau kinetic equation for a dense electron gas is considered. Being one of the most simple kinetic equations, it still retains essential physical features of a correlated manyβparticle system, such as selfconsistent static screening and Pauli bloc
Computation of the spatial derivatives with non-local differential operators, such as the Fourier pseudospectral method, may cause strong numerical artifacts in the form of noncausal ringing. This situation occurs when regular grids are used. The problem is attacked by using a staggered pseudospectr
