Abstract
The quasilinear theory of the Wigner-Poisson system in one spatial dimension is examined. Conservation
laws and properties of the stationary solutions are determined. Quantum effects are shown to manifest themselves
in transient periodic oscillations of the averaged Wigner function in velocity space. The quantum
quasilinear theory is checked against numerical simulations of the bump-on-tail and two-stream instabilities.
The predicted wavelength of the oscillations in velocity space agrees well with the numerical results.
