Derivation of kinetic equation, up to order λ6, for the interaction between radiation and a two-level system. Part I
Françoise Hénin, Michel De Haan
In the bare particle representation, the kinetic operator Ψ(z) and its first derivatives play a very important role in the asymptotic equation for the evolution of the diagonal elements of the density matrix. Explicit expressions for these operators are derived, up to order λ6, for the interaction between radiation and a two level system. The transformation to the dressed particle distribution function will be given in a next paper.
