In previous work [1,2,3], we have shown in our model that the (tunnel-ionization) time-delay measured in the attoclock experiment can be precisely described in the adiabatic and nonadiabatic field calibrations. Furthermore, the barrier (tunneling) time-delay itself can be determined from the difference between the time-delays of the adiabatic and nonadiabatic tunnel-ionization, which shows excellent agreement with the experimental results. Remarkably, the tunneling time-delay exhibits a universal behavior with disentangled contributions. Furthermore, we find that in the weak measurement limit, the barrier time-delay corresponds to the Larmor-clock time-delay and the interaction time within the barrier region [1]. We further discuss quantum superluminality in the framework of the attoclock [4].
