Abstract

François Bardou and Dominique Boosé recently published1 their discovery of a new induced tunnel effect, they named quantum evaporation. In this work they showed that, for a one-dimensional electron reflecting on an energy barrier, the stationary character of its eigen-functions could be broken under special conditions. If a small momentum is transferred to the electron at the time it reflects on the barrier, its wave-function is projected on the complete set of its stationary eigen-functions. A small momentum means that the energy transfer that accompanies the momentum transfer is negligible compared to the barrier height or at least that it does not allow for a jump of the particle above the barrier. The tunnelling probability of the electron is strongly enhanced by the momentum perturbation because the weight of the eigen-states with energies above the barrier becomes preponderant in the calculation of the tunnelling probability. This probability enhancement is independent on the sign of the momentum transfer: the electron can be pushed toward or pull out of the barrier; it only depends on the momentum amplitude in a quadratic way. The authors have showed that the momentum transfer is equivalent to a kinetic translation of the barrier.
