Interference mechanism of seemingly superluminal tunnelling
D. Sokolovski, E. Akhmatskaya
TL;DR
This paper explores the interference mechanisms behind seemingly superluminal tunnelling, revealing how wave packets are reconstructed from their front tails, challenging simpler explanations of the phenomenon.
Contribution
It uncovers the interference mechanism responsible for superluminal tunnelling and emphasizes its complexity beyond simple models.
Findings
Superluminal tunnelling involves a subtle interference process.
Wave packet shape can be reconstructed from the front tail.
The effect is unlikely to be explained by simpler models.
Abstract
Apparently 'superluminal' transmission, e.g., in quantum tunnelling and its variants, occurs via a subtle interference mechanism which allows reconstruction of the entire spacial shape of a wave packet from its front tail. It is unlikely that the effect could be described adequately in simpler terms.
