Impossibility of Vedenov–Rudakov’s plasma modulational instability as one more illustration of the inappropriateness of the recipes of nonequilibrium statistical mechanics

It is shown that collisionless dissipation of Langmuir turbulence is always sufficient for suppression of Vedenov–Rudakov’s plasma modulational instability, i.e., the plasma hydrodynamic instability with respect to long-wavelength spatial modulation in plasma density and coordinated modulation in the density of Langmuir turbulence.
