Query: Modulational interactions in quantum plasmas   A formalism for treating modulational interactions of electrostatic fields in
collisionless quantum plasmas is developed, based on the kinetic Wigner-Poisson
model of quantum plasma. This formalism can be used in a range of problems of
nonlinear interaction between electrostatic fields in a quantum plasma, such as
development of turbulence, self-organization, as well as transition from the
weak turbulent state to strong turbulence. In particular, using this formalism,
we obtain the kinetic quantum Zakharov equations, that describe nonlinear
coupling of high frequency Langmuir waves to low frequency plasma density
variations, for cases of non-degenerate and degenerate plasma electrons.
