The meaning of group delay in barrier tunneling: A reexamination of superluminal group velocities

It is widely believed that photons tunnel through bandgaps with group velocities exceeding c. Here we examine the experimental evidence and show that the measured group delays are photon lifetimes as opposed to transit times.
