The quantum tunneling is an overcoming of the potential barrier by a particle, which has no sufficient energy to do this. This is a property of the leptons (electrons), because they are relatively lightweight and large vortices with a spatially spread mass.

The vortex partially overcomes a barrier, although its center is located in front of the barrier. The smaller the geometrical barrier width, the greater is the electrostatic force, which acts behind the barrier, partially compensates the barrier resistance, and so reduces the actual barrier potential.

The barrier overcoming is caused by the chaotic thermal motion or the electric current, and is statistical in nature.

The Josephson effect is a similar quantum tunneling for the dielectric materials.
