    "abstract": "The mechanism of superluminal traversal time through a potential well or\npotential barrier is investigated from the viewpoint of interference between\nmultiple finite wave packets, due to the multiple reflections inside the well\nor barrier. In the case of potential-well traveling that is classically\nallowed, each of the successively transmitted constituents is delayed by a\nsubluminal time. When the thickness of the well is much smaller in comparision\nwith a characteristic length of the incident wave packet, the reshaped wave\npacket in transmission maintains the profile of the incident wave packet. In\nthe case of potential-barrier tunneling that is classically forbidden, though\neach of the successively transmitted constituents is delayed by a time that is\nindependent of the barrier thickness, the interference between multiple\ntransmitted constituents explains the barrier-thickness dependence of the\ntraversal time for thin barriers and its barrier-thickness independence for\nthick barriers. This manifests the nature of Hartman effect.",
