EFFECT OF A HIGH-FREQUENCY ELECTROMAGNETIC-FIELD ON TUNNELING TRANSITIONS BETWEEN 2 LOCALIZED STATES

The effect of a constant and an alternating electric field on the tunneling of a quantum particle between two localized states is studied. The tunneling current for two one-dimensional potential wells of zero radius is calculated. Wells of both different and equal intensities are considered. In the latter case, a resonance arises when the frequency of the alternating field is appropriately chosen. The values obtained for the currents make it possible to conclude that the enhancement of the tunneling effect by an alternating field is observable.
