k—quantum nonlinear Jaynes—Cummings model in two trapped ions

摘要

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.
