Description

We calculate tunneling rates of two interacting atoms confined in an anharmonic trap. We consider the ground and excited states with respect to relative and center-of-mass motions and observe a monotonic and non-monotonic behavior of the tunneling rates as a function of the coupling strength. The origin of a such behavior lies in an initial wave-packet distribution. We also find that the only possible tunneling scenario in the considered cases is a sequential particle tunneling. Another interesting feature of the tunneling from the excited states is a two-stage decay in which the population of the atoms of different quantum states during the tunneling process occurs.
