Analysis of wavepacket tunneling with the method of Laplace transformation
Abstract
We use the method of Laplace transformation to determine the dynamics of a wavepacket that passes a barrier by tunneling. We investigate the transmitted wavepacket and find that it can be resolved into a sequence of subsequent wave packages. This result sheds new light on the Hartman effect for the tunneling time and gives a possible explanation for an experimental result obtained by Spielmann et al.
