Аннотация:
We consider two interacting atoms subject to a one-dimensional anharmonic trap and linear magnetic-field gradient. This system has been recently investigated by the Heidelberg group in the experiment on two 6Li atoms. In the present research, the tunneling of two cold 6Li atoms, initially prepared in the center-of-mass and relative motion excited states, is explored and full time-dependent simulation of the tunneling dynamics is performed. The dynamics is analyzed for the interatomic coupling strength ranging from strong attraction to strong repulsion.
