Tunneling time in attosecond experiments, strong field and ultra-fast science — •Ossama Kullie — Theoretical physics, institute for physics, university of Kassel, Germany.

I present a theoretical model of the tunneling time and the tunneling process in attosecond and strong field experiments, leading to a relation which performs an excellent estimation for the tunneling time, where we address the important case of the He-atom [2]. The tunneling time is also featured as the time of passage similar to the Einstein’s photon box Gedanken experiment (EPGE), and our model can be seen as a realization of the EPGE. Our work tackles an important case study for the theory of time in quantum mechanics, and is very promising for the search for a (general) time operator in quantum mechanics. The work can be seen as a new fundamental step in dealing with the tunneling time in strong field and ultra-fast science, and is appealing for more elaborate treatments using quantum wave packet dynamics and especially for complex atoms and molecules.
