Definition: Quantum Tunneling Effect is a quantum mechanical process where particles penetrate through a barrier that they classically would not be able to cross. This intriguing phenomenon plays a ...

A tunnel that can take billions of years to dig, and makes The Shawshank Redemption look like child's play. Mathematically, nonperturbative quantum effects are much more difficult to describe than ...

such as the Josephson effect, where a supercurrent can flow through the junction without any applied voltage. SIS junctions are used in superconducting quantum interference devices (SQUIDs), which are ...

In effect, hydrogen "tunnels" through the activation barrier. Particles of different energies tunnel at various heights. The thinner barrier at the top promotes tunneling, but few particles have ...
