摘要
A generalized kinetic theory of gaseous ensembles of particles with variable charges is proposed. The evolution of the ensembles due to the mutual particle collisions is investigated. The cases of inhomogeneous and randomly fluctuating charges are studied. It is shown that the particle temperature in such ensembles increases with time, and in some cases can grow by orders of magnitude. The theory is compared with the molecular-dynamics simulations, the relevance to typical experimental conditions is analyzed, and astrophysical implications are discussed.
