    Interaction of two-level atomic system with a single-mode radiation field
    (Springer, 1997) Hakioğlu, Tuğrul; Shumovsky, Alexander S.; Hakioğlu, Tuğrul
    The Dicke model is examined in the limit of large number of atoms and /or large number of excitations. Superfluous instabilities arising from the rotating wave approximation is examined and counterrotating terms are shown to be crucial for the correct dynamical evolution in these limits.
