Applications of a macroscopic and microscopic nature are given of the Markov formalism, developed in the previous paper, for finding the pair-correlation function, two-point covariance function, and spectral intensities from the phenomenological transport equations, transitions, and scattering. As macroscopic examples, we discuss Rayleigh diffusion, Coulomb correlations, and space-charge-limited flow in solids. The diffusion equation is shown to be not strictly Markovian, though correct Langevin diffusion sources are easily found. Dielectric relaxation is shown to be a macroscopic manifestation of Coulomb correlations in a plasma. The Λ theorem of the previous paper yields for the pair-correlation functions the original Debye-Hückel result plus a δ term. The spectra for space-charge-limited flow due to single-carrier injection are treated with the Green's-function procedure. The discrepancies between existing theories are removed since the Coulomb correlations in the steady state are shown to be not of the Debye-Hückel type. As microscopic applications, we consider ideal gases in the presence of streaming due to fields, an extension of Lax's work. The connection with the BBGK two-point equations for one- and two-body collisions is established. Finally, we integrate over the stochastic Boltzmann equation to obtain stochastic hydrodynamic equations. These provide a microscopic basis is for the noise sources associated with electrical conduction, heat conduction, and with the Navier-Stokes equation. Results for the hot-electron Boltzmann gas are compared with those of Price.
