Chaotic behavior in the Raman interaction of a trapped ultracold ion with two traveling wave lasers

By means of the Bloch-Maxwell equation, the Raman interaction of a trapped ultracold ion with two traveling wave lasers is treated semiclassically. As the model works without limitation of the Lamb-Dicke limit and the weak ex citation regime, we study chaotic behavior of the system in the wide range of the parameters. It is shown that the chaotic behavior is more and more p ronounced with the increase of the Lamb-Dicke parameter and Rabi frequency, and can be exhibited experimentally by using quantum jump technique.
