| Abstract: | The influence of parameters such as the strength andfrequency of a periodic driving force on the tunneling dynamics isinvestigated in a symmetric triple-well potential. It is shown thatfor some special values of the parameters, tunneling could beenhanced considerably or suppressed completely. Quantum fluctuationduring the tunneling is discussed as well and the numerical resultsare presented and analysed by virtue of Floquet formalism. |
