Cooper pairs undergo this process in a Josephson junction to allow a current to flow through an insulator.
A very similar phenomenon to this in optics is known as frustrated total internal reflection. A 2006 paper showed that enzymes make use of this process, which is also the basis of operation for the Esaki diode. Nuclear reactions depend upon this process to overcome the Coulomb repulsion between nuclei, and the resonant form of this phenomenon, which exponentially depends on energy and distance, occurs when electrons have energies in the conduction band. Cooper pairs undergo this process in a Josephson junction to allow a current to flow through an insulator. For 10 points, name this quantum effect in which a particle travels through a classically forbidden barrier.
