Vlasov equation

Vlasov equation

[′vla·sȯf i‚kwā·zhən]
(plasma physics)
A modification of the Boltzmann transport equation for the study of a plasma, in which particles interact only through the mutually induced space-charge field, and collisions are assumed to be negligible. Also known as collisionless Boltzmann equation.

This equation is a semi-classical quantum Vlasov equation. However, unlike the classical case that Df/Dt [not equal to] 0 owing to the RHS quantum h-term in Eq.(4), the distribution function f is not preserved, except for linear electric fields that leads to a vanishing h-term due to [[partial derivative].sup.3][phi]/[partial derivative][x.sup.3] = 0, along with the classical characteristic equations of the electrons:
In the absence of an external magnetic field, [B.sub.0], replacing f with [f.sub.0] + [f.sub.1] and [phi] = [[phi].sub.1] in the Wigner-Poisson equation, Eq.(6), offers the linearized semi-classical quantum Vlasov equation in which Eq.(5) is kept unchanged:

A more general class of stochastic systems is governed by McKean- Vlasov equations in which the coefficients are not only functions of the state but also of the probability measure induced by the state itself.
