Are particle and photon tunneling and filling in barriers local or non-local phenomena? (English) Zbl 1020.81974

Summary: It is shown that particle and photon tunneling exhibits a non-local behaviour. This is also true for the wave filling in a semiclosed barrier with a dead stopper. In this connection, we discuss and define for the first time the penetration time of such a barrier in the wave-packet approach.
