Tunneling time, the Hartman effect, and superluminality: A proposed resolution of an old paradox

HG Winful - Physics Reports, 2006 - Elsevier
The issue of tunneling time is replete with controversy and paradoxes. The controversy
stems from the fact that many tunneling time definitions seem to predict superluminal …
