Enhanced quantum tunnelling - PB03

In this third tutorial of the series on quantum particles in “boxes”, we show how the rate of quantum tunnelling of a particle through a barrier can be enhanced by placing identical boxes next to each other. Instead of the slow exponential decay that we found in the last tutorial, we find that the probability to find the particle in either box rapidly oscillates.

These so called Rabi oscillations are the result of the interaction of identical energy levels from each quantum box and can be conceptually understood from the perspective of coupled classical pendulums.
