| Abstract: | The influence of parameters such as the strength and frequency of a periodic driving force on the tunneling dynamics is investigated in a symmetric triple-well potential. It is shown that for some special values of the parameters, tunneling could be enhanced considerably or suppressed completely. Quantum fluctuation during the tunneling is discussed as well and the numerical results are presented and analysed by virtue of Floquet formalism. |
| Keywords: | triple-well potential non-resonant tunneling resonant tunneling Floquet theorem quantum fluctuation |
