Tunneling Time of Particles Through a Potential Barrier

         

摘要

A new tunneling time is proposed by introducing the transfer speed of energy carried by tunneling particles. This speed is similar to the energy transfer speed in electromagnetism, and with the tunneling time, the well-known superluminality may be avoided. The low energy limit, the critical limit, and the opaque limit are considered,which are physically meaningful. Comparisons with dwell time and Biittiker and Landauer's semiclassical time are also made.
