The Quantum Superluminality of Tunnel-ionization — •Ossama Kullie1 and Igor Ivanov2 — 1Department of Mathematics and Natural Sciences. University of Kassel, 34132 Kassel, Germany. — 2Department of Fundamental and Theoretical Physics, Australian National University, Australia
Tunneling is one of the most interesting phenomena in quantum physics. In our tunnel-ionization model [1, 2, 3], we have shown that the time-delay of the adiabatic and nonadiabatic tunnel-ionization determines the barrier time-delay in a good agreement with the attoclock measurement and that it corresponds to the dwell time and the interaction time. In the present work, we show that the barrier time-delay for H-like atoms with a large nuclear charge can be superluminal (quantum superluminality), which can be experimentally validated using the attoclock scheme. Furthermore, we accompany our model with the numerical integration of time-dependent Schödinger equation (NTTDSE), where we expect good agreement with our model as in earlier work [2]. We investigate the quantum superluminality for the different experimental calibrations (adiabatic and nonadiabatic tunnel-ionization) of the attoclock [4] and discuss its interpretation. [1] O.
