| 内容記述 | We numerically study coherent tunneling oscillations of the particles between two levels in a double-well potential in the presence of anharmonic periodic potentials. Extremely short driving pulses modify the tunneling coefficient to ef f= cos A, where is the bare tunneling coefficient without the driving field and A is the pulse area of the driving wave form. The modulation amplitude of the ef f gradually decreases as the driving wave form becomes broad and is given by ef f= J0 A for the sinusoidal modulation, where J0 x denotes the ordinary Bessel function of order zero. Theoretical derivation of the effective tunneling coefficient ef f = cos A is also shown for a periodic kick with alternating sign by means of the transfer matrix formula. |
