Chaotic atomic tunneling between two periodically driven Bose-Einstein condensates

摘要

The tunneling effect of a weakly coupled Bose-Einstein condensate held in a double-well potential is described by the coupling parameter K. When the parameter is a periodic function of time, K = K(t), perturbed solution of the system is analytically insolvable and numerically incomputable that makes the corresponding atomic tunneling the chaotic one. However, the chaotic atomic tunneling can be controlled by adjusting the initial conditions and system parameters.
