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.
