Time operator, real tunneling time in strong field interaction and the attoclock. — •Ossama Kullie — Institute for Physics, University of Kassel.

In the present work [1], we show that our real tunneling time relation derived in earlier works [2] can be derived from an observable or a time operator, which obeys an ordinary commutation relation. Moreover, we show that our real tunneling time can also be constructed from the well-known Aharonov-Bohm time operator. This shows that the specific form of the time operator is not decisive, and dynamical time operators relate identically to the intrinsic time of the system. It con- trasts the famous Pauli theorem, and confirms the fact that time is an observable, i.e. the existence of time operator and that the time is not a parameter in quantum mechanics. Furthermore, we discuss the relations with different types of tunneling times such as Eisenbud- Wigner time, dwell time and the statistically defined tunneling time. We conclude with the hotly debated interpretation of the attoclock measurement and the advantage of the real tunneling time picture versus the imaginary one. [1] O. Kullie, Phys. Rep. 2020,2, 233.
