Time operator, real tunneling in strong field interaction and the attoclok — •Ossama Kullie — Theoretical Physics, Institute of Physics, University of Kassel

In our work we found a relation to calculate the tunneling time in the attoclock experiment in both cases, the adiabatic and nonadiabatic field calibration [1,2]. Our real tunneling time can be derived from an observable, i.e. a time-energy ordinary commutation relation or a time operator. In addition, it is constructed from Fujiwara-Kobe time operator and the well-known Aharonov-Bohm time operator. The specific form of the time operator is not decisive and a dynamical time operator of a system refers to the intrinsic time of the system. The result contrasts 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 [3,4]. [1] To be submitted. [2] O. kullie, PRA 92, 052118 (2015).
