The attoclock and its interpretations, theoretically and experimentally — •Ossama Kullie — Institute of Physics, Department of Mathematics and Natural Science, 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 or an imaginary quantity. A related issue, whether time is an observable or a parameter in quantum mechanics. Another point is the statistical interpretation of the tunneling time, nevertheless we show that 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. We give a detailed picture concerning these issues, and discuss some features for future works on both sides, experiment and theory. [1] O.
