Tunneling time in attosecond experiments, Time in Quantum Mechanics and the realization of the Bohr-Einstein photon box Gedanken experiment. — •Ossama Kullie — Institute of Physic, University of Kassel, Germany

Tunneling time in attosecond and strong field experiments is one of the most controversial issues in today’s research, because of its importance to the theory of time, the time operator and the time quantum mechanics. In [1,2] I present a theoretical model of the tunneling time for attosecond experiment of the He atom [3]. The model offers a relation which performs an excellent estimation for the tunneling time in attosecond and strong-field experiments (for the He atom [3]). The tunneling time estimation is found by utilizing the time-energy uncertainty relation and represents a quantum clock. The tunneling time is also featured as the time of passage through the barrier similar to Einsteins photon-box Gedanken experiment [1]. This 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 [4]. The work can be seen as a fundamental step in dealing with the tunneling time in strong-field and ultrafast science and is appealing for more elaborate treatments using quantum wave-packet dynamics and especially for complex atoms and molecules [2,4].
