We numerically study the controllability of quantum dynamics in perturbed one-dimensional double-well potential by using an optimal control theory. As the perturbation strength is small the dynamics of the initially localized Gaussian wavepacket shows coherent oscillation between the wells. It is found that as there is an increase in strength and/or the number of frequency components of perturbation,...
We numerically study a wavepacket tunneling in one-dimensional symmetric double-well potential with a coherent perturbation. In the classical dynamics, such a system shows chaotic behavior by the classical driving force. In the present paper, we show how the tunneling dynamics depends on the parameters such as the amplitude and frequency of the perturbation in comparison with the classical counterpart...
