The tunneling time, a theoretical model for real tunneling time and the attosecond experimental results. — •Ossama Kullie — University of Kassel, Fachbereich 10, Heinrichplett str. 41, 34132 Kassel

In this work we discuss our theoretical tunnelings model for real tunneling time [1,2,3], with a comparison to the results of attosecond experiments for He-atom and H-atom, where good agreements with the experiments are found. However, although the tunneling time is hot debated with a controversial discussions, it offers a fruitful opportunity to understand time measurement and the time in quantum mechanics. In our model a real tunneling time is suggested and is compared with other model including time-dependent Schroedinger equation, and Feynman bath integral or the statistical approach of the tunneling time. In addition, we will see that there are crucial points for higher intensities, in particular where the electric filed strength is higher than the atomic filed strength, this opens some questions on the experimental side.
