The Attoclock and its Interpretations, Theoretically and Experimentally — •Ossama Kullie — Institute for Physics, University of Kassel.

The measurement of the tunneling time in experiments with intense short laser pulse, termed attoclock, triggered a hot debate about the tunneling time and the separation into two regimes of ionization, the multiphoton and the tunneling. Theoretically, a crucial issue is the tunneling time, whether it is a real, which implies that time is an observable in QM, or an imaginary quantity, which implies that time is a parameter in QM. Another point is the statistical interpretation of the tunneling time. nevertheless, our real tunneling time is conform with the statistical point of view. Experimentally the issue is crucial since the result depends on the field strength calibration, and its consequence for the tunneling or multiphoton ionization regimes and hence the interpretation of the theoretical result. In our picture we illustrate these issues in the theory with comperision to experimental result. [1] O. Kullie. Phys. Rep. 2020,2, 233. [2] O. K. Phys. Rev. A. 92, 052118 (2015), [3] O. K.
