Determination of the mean tunneling flight time in the Büttiker-Landauer oscillating-barrier model as the reflected phase time
R Ianconescu, E Pollak - Physical Review A, 2021 - APS
The oscillating-barrier model was used by Büttiker and Landauer to determine a “traversal
time for tunneling.” The model sets a timescale but is not the physically measured flight time …

Superluminal tunneling times without superluminal signaling: Fading of the MacColl-Hartman effect at early times
A curious feature of quantum tunneling known as the MacColl-Hartman effect results in the
numerical observation that particles can traverse a barrier with effective superluminal speed …
