VI.4 Solutions of the Boltzmann equation. We now turn to a discussion of the solution of the Boltzmann equation. VI.4.1 Equilibrium distributions. According to the H-theorem, H(t) is a decreasing function of time—at least when the assumption of molecular chaos holds.
Diffusion equation. Solve B.k.e. for weakly nonuniform density distribution (and no external field!). Here j and n is particle number current and density. Next, use angular harmonic decomposition f (p) = f0(p) + f1(p) + ..., f1 ∝ cos θ, sin θ and relate f1 with a gradient of f0.

The proportionality constant \(k\) (or \(k_B\)) is named after Ludwig Boltzmann. It plays a central role in all statistical thermodynamics. The Boltzmann factor is used to approximate the fraction of particles in a large system. The Boltzmann factor is given by: \(e^{-\beta E_i}\).
Lecture 1: Derivation of the Boltzmann Equation. Introduction. The basic model describing MHD and transport theory in a plasma is the Boltzmann-Maxwell equations. This is a coupled set of kinetic equations and electromagnetic equations. Initially the full set of Maxwell’s equation is maintained.

Jun 14, 2021 · In developing Boltzmann statistics, we assume that we can tell different molecules of the same substance apart. We say that the molecules are distinguishable. This assumption is valid for molecules that occupy lattice sites in a crystal.
