Abstract  We have obtained a k-quantum nonlinear Jaynes-Cummings model for two trapped ions interacting with laser beams resonant to the kth red side-band of the centre-of-mass mode, far from the Lamb-Dicke regime. The exact analytic solution shows the existence of quantum collapses and revivals of the occupation of two atoms.
Keywords:  nonlinear Jaynes-Cummings model      occupation      collapse and revival
