Dynamical properties of a two-level system with arbitrary nonlinearities

[摘要] We investigate some aspects of a generalized JC-model which include arbitrary forms of non-linearities of both the field and the intensity-dependent atom–field coupling. We obtain an exactly analytic solution of the model, by means of which we identify and numerically demonstrate the region of parameters where significantly large entanglement can be obtained.
