Klein paradox

名詞

(quantum mechanics) 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∼mc², the barrier is nearly transparent; moreover, as the potential approaches infinity, the reflection diminishes and the electron is always transmitted.

日本語の意味

クラインパラドックス：量子力学において、ディラック方程式を用いて電子のポテンシャル障壁における散乱問題を解析する際に、通常の非相対論的な電子トンネル効果（指数減衰を伴う）とは対照的に、ポテンシャルが電子の質量エネルギー程度（V≈mc²）に達すると障壁がほぼ透明になり、ポテンシャルが無限に近づくと反射が減少し、常に透過するという予想外の現象を示すものです

During the seminar, the professor explained the Klein paradox and how a potential comparable to the electron's rest energy can make the barrier almost transparent.

セミナーで教授は、ディラック方程式を電子の散乱問題に適用したときに生じる驚くべき相対論的散乱の結果、すなわちポテンシャルが電子の静止エネルギーと同程度の場合に障壁がほとんど透過的になることについて説明した。
