Equivalence between the real time Feynman histories and the quantum shutter approaches for the "passage time" in tunneling

Gaston Garcia-Calderon, Jorge Villavicencio, Norifumi Yamada

We show the equivalence of the functions $G_{\mathrm{p}}(t)$ and $|\Psi (d,t){|}^2$ for the ``passage time'' in tunneling. The former, obtained within the framework of the real time Feynman h…
