Klein paradox

English

Etymology

Discovered by physicist Template:W in 1929.

Noun

1. Template:Lb A surprising result of applying the Dirac equation to the problem of electron scattering from a potential barrier. In non-relativistic quantum mechanics, electron tunnelling into a barrier is observed, with exponential damping. However, if the potential is of the order of the electron mass, $V\sim m{c}^2$, the barrier is nearly transparent; moreover, as the potential approaches infinity, the reflection diminishes and the electron is always transmitted.
