The dynamics of a 1-d cubic oscillator having a time-dependent harmonic force constant is studied numerically by invoking the time-dependent Fourier grid Hamiltonian method. The temporal variation in K t causes the tunneling rate constant to decrease or increase, depending upon the nature of the tim
