A Probability Distribution for Quantum Tunneling Times

Figure 2

Probability distribution for the tunneling times , obtained by Monte Carlo samplings of -values from the distribution and then transforming these to time values through . The parameters are the same as in the corresponding plots in Figure 1 and are all expressed in Rydberg atomic units. Top: . Bottom: . These plots are in the same range and scale and can be compared. The vertical grey line in both plots corresponds to the time the light takes to traverse the barrier distance. The ticks in the horizontal axes correspond to the light time, the minimum, the median and the maximum values of in the histogram (in the bottom plot the maximum is out of the plot’s range).
