Physical mechanism of superluminal traversal time: interference between multiple finite wave packets
Xi Chen, Chun-Fang Li
The mechanism of superluminal traversal time through a potential well or potential barrier is investigated from the viewpoint of interference between multiple finite wave packets,…

Negative group delay for Dirac particles traveling through a potential well
Xi Chen, Chun-Fang Li
The properties of group delay for Dirac particles traveling through a potential well are investigated. A necessary condition is put forward for the group delay to be negative. It i…

Resonance-enhanced group delay times in an asymmetric single quantum barrier
Chun-Fang Li
It is shown that the transmission and reflection group delay times in an asymmetric single quantum barrier are greatly enhanced by the transmission resonance when the energy of inc…
