tunneling

tun·nel·ing

T0413975 (tŭn′ə-lĭng)n. In quantum mechanics, the passing of a particle through a seemingly impenetrable barrier without a cause that is explainable by classical physics.

tun•nel•ing

(ˈtʌn l ɪŋ)
n. a quantum-mechanical process, forbidden in classical mechanics, in which an atomic particle passes through a region where its potential energy is higher than its total energy. Also, esp. Brit.,tun′nel•ling. Also called tun′nel effect`. [1935–40]

tunneling

Illegally diverting company funds or lucrative contracts to a company insider or majority shareholder thereby lessening the value of the holdings of minor shareholders.

tunneling

tunneling,

quantum-mechanical effect by which a particle can penetrate a barrier into a region of space that would be forbidden by ordinary classical mechanics. Tunneling is a direct result of the wavelike properties of particles; the wave associated with a particle "decays" through a barrier—the amplitude decreases—but the amplitude of the wave on the other side of the barrier is large enough that there is a finite probability of finding the particle there. The theory of tunneling has been successfully applied to understand alpha decay, in which a heavy nucleus decays into a lighter nucleus and emits an alpha particle (helium nucleus).
