Equilibrium for radiation in a homogeneous plasma

Russel E. Caflisch, C. David Levermore

Research output: Contribution to journalArticlepeer-review


Entropy increase and comparison principles are found for the Fokker-Planck equation for the radiation field in a homogeneous plasma with constant electron temperature. When emission-absorption is neglected, this is used to find equilibrium distributions that have the form of a Planck distribution plus a δ function at zero photon energy. For distributions below the Planck and with emission-absorption included, a rate of entropy increase is obtained. Numerical results confirm these conclusions.
