Transient tunneling effects of resonance doublets in triple barrier systems

Quantum Physics 2009-11-07 v1

Abstract

Transient tunneling effects in triple barrier systems are investigated by considering a time-dependent solution to the Schr\"{o}dinger equation with a cutoff wave initial condition. We derive a two-level formula for incidence energies EE near the first resonance doublet of the system. Based on that expression we find that the probability density along the internal region of the potential, is governed by three oscillation frequencies: one of them refers to the well known Bohr frequency, given in terms of the first and second resonance energies of the doublet, and the two others, represent a coupling with the incidence energy EE. This allows to manipulate the above frequencies to control the tunneling transient behavior of the probability density in the short-time regime
