A Probability Distribution for Quantum Tunneling Times

Figure 1

Stationary transmission clock time (green) and the distributions (orange and arbitrary scale) and (blue, dashed, and arbitrary scale) for the transmitted and incident wave packets, respectively. Rydberg atomic units are used in all plots; the tunneling energies correspond to , corresponding to a barrier height (the maximum tunneling wave number is shown by a vertical grey line in the plots). In both plots the incident wave packet parameters are . Top: barrier width . Bottom: barrier width .
