Perfect Transmission

摘要

In quantum mechanics, when a particle encounters a potential energy barrier that it cannot classically overcome, most of the time that particle will be reflected, but some of the time it will be able to make it through to the other side. The probability of tunneling is generally less than 1; however, in the special case where there is dissipation in the system and instead of a single barrier there is a double barrier supporting a resonant state, perfect transmission has been predicted to occur under certain circumstances.
