| contents | The measurement of the tunneling time-delay is hotly debated and remains controversial.
In previous works, we showed that a model that accurately describes the time-delay measured by the attoclock experiment in adiabatic and
nonadiabatic field calibrations.
In the present work, we show that the tunneling time reveals a universal behavior with disentangled contributions.
Even more remarkable is that the barrier tunneling time-delay can be convincingly defined and determined from the difference between the
time-delay of adiabatic and nonadiabatic tunnel-ionization, which also show good agreement with experimental results.
Furthermore, we illustrate that in the weak measurement limit, the barrier time-delay corresponds to the Larmor-clock time and the interaction time within the barrier. |
