Field emission of electrons is explained by this phenomenon.
In Yang-Mills theories, BPST instantons are solutions for this phenomenon between two vacua of different Chern-Simons numbers. Field emission of electrons is explained by this phenomenon. e to the negative two over h-bar times integral between two points of root two m times quantity V of x minus E, dx is the derived probability for this phenomenon when using the WKB approximation. A diode that operates via this phenomenon was created by Leo Esaki. Fusion occurs via this process in the Gamow window because nuclei don't have to overcome the Coulomb barrier. For 10 points, name this classically forbidden phenomenon in which a particle passes through a potential barrier even though its energy is less than the barrier's.
