Abstract:
In the first order of semiclassical perturbation theory, with allowance for many-quantum
transitions, a study is made of resonance tunneling through a two-hump nonstationary
potential. The problem is reduced to the solution of a functional equation for the transmission
probability amplitude. This equation is solved in general form for the case of
nonresonance tunneling. A condition of suppression of resonance by nonstationary
effects is obtained. The transmission amplitude is found in the case when the twohump
potential oscillates as a whole. Periodic, quasiperiodie, and random nonstationary
perturbations are considered.
