Physical interpretation of the quantum two-stream instability

Abstract

The unexpected features of the two-stream instability in electrostatic quantum plasmas are interpreted in terms of the coupling of approximate fast and slow waves. This is accomplished thanks to the factorization of the dispersion relation into different sectors carrying positive or negative energy. The concept of negative and positive energy waves, therefore, is useful not only for classical, but for quantum plasmas as well.
