摘要：

It is reported that the phase time of particles passing through a potential well is negative when the energy of incident particles and the thickness of potential well satisfy certain conditions. Similar results are also found in a fully-relativistic optical analog. The 2-dimensional optical case gives rise to a lateral shift of the wave packet. It is shown that the phase-time associated lateral shift can also be negative. (C) 2000 Published by Elsevier Science B.V.
