Universal Behavior of Tunneling Time and Disentangling Tunneling Time and Barrier Time-Delay in Attoclock Experiments — •Ossama Kullie1 and Igor Ivanov2 — 1Theoretical Physics, Department of Mathematics and Natural Science, University of Kassel, Germany — 2Department of Fundamental and Theoretical Physics, Australian National University, Australia
In a model we showed that the (tunnel-ionization) time-delay measured by the attoclock experiment can be described accurately in adiabatic and nonadiabatic field calibrations. Moreover, the barrier tunneling time-delay itself can be determined from the difference between the time-delay of adiabatic and nonadiabatic tunnel-ionization, showing good agreement with experimental results. What is particularly striking and interesting is that we have shown that the tunneling time exhibits a universal behavior with disentangled contributions. In Addition, we find that the weak measurement limit, the barrier time-delay corresponds to the Larmor-clock time and the interaction time within the barrier. [1] Submitted to J. Phyis. Comm. (2024).
