Abstract: Generalized models are presented for the interaction between an N-level atom and (N−1) modes. Spin-1 operators are used to describe the 3-level atom, and the generators of the U(N) group are used in the general case. Different statistical quantities related to the photons and the atmoic system are calculated. Multiphoton processes are discussed. A model is presented in the 3-level atom and 2-mode system, in which infinite series tend to closed forms, for thermal and coherent distributions for the modes.
