| contents | The generating functions for density matrix elements of the Jaynes-Cummings model with cavity damping are analysed in terms of their eigenmodes, which are characterised by a specific temporal behaviour. These eigenmodes are shown to be proportional to particular generalised hypergeometric functions. The relative weights of these eigenmodes in the generating functions are determined by the initial conditions of the model. These weights are found by deriving orthogonality relations involving adjoint modes. In an example it is shown how the time-dependent density matrix elements and the related factorial moments can be extracted from the eigenmode decompositions of the generating functions. |
