Clocking the Quantum Sojourn Time: Spurious Scatterings and Correction to the Larmor Clock
We revisit the notions of the quantum-mechanical sojourn time in the context of the quantum clocks to enquire whether the sojourn time be clocked without the clock affecting the dynamics of the waveExpand
Role of reflections in the generation of a time delay in strong-field ionization
Against the background of recent attoclock experiments, the problem of time delay in tunneling ionization is revisited. The origin of time delay at the tunnel exit is analysed, underlining the twoExpand

This article will explain the tunneling phenomenon that occurs in ammonia molecules from the perspective of trajectory-based quantum dynamics, rather than the usual quantum probability perspective. Expand


Attosecond angular streaking and tunnelling time in atomic hydrogen
Simulation and measurement of the photoionization of atomic hydrogen at attosecond resolution confirm that the tunnelling of the ejected electron is instantaneous, and identify the Coulomb potential as the sole cause of the measured angle between the directions of electron emission and peak electric field.

Direct probing of tunneling time in strong-field ionization processes by time-dependent wave packets.
We propose a straightforward approach to directly probe the tunneling time by observing the transition of photoelectron wave packets in strong-field ionization processes, where Coulomb potentials doExpand
Determination of the Ionization Time Using Attosecond Photoelectron Interferometry.
A novel attosecond photoelectron interferometer is proposed, which is based on the interference of the direct and near-forward rescattering electron wave packets, to determine the time information characterizing the tunneling process. Expand
Longitudinal Momentum of Electron at the Tunneling Exit
The longitudinal momentum of the electron at the tunneling exit is a useful quantity to make sense of the tunneling ionization process. It was usually assumed to be zero from a classical argument,Expand
No time at the end of the tunnel
Modern atto-second experiments seek to provide an insight into a long standing question: “how much time does a tunnelling particle spend in the barrier?” Traditionally, quantum theory relates thisExpand
Trajectory-free ionization times in strong-field ionization
Using a purely quantum mechanical approach without trajectories, we are able to compute momentum-resolved ionization times of electrons released by the strong-field ionization of atoms. For theExpand

Tunneling exit characteristics from classical backpropagation of an ionized electron wave packet
We investigate tunneling ionization of a single active electron with a strong and short laser pulse, circularly polarized. With the recently proposed backpropagation method, we can compare differentExpand
Under-the-Tunneling-Barrier Recollisions in Strong-Field Ionization.
The interference of the direct and the under-the-barrier recolliding quantum orbits are shown to induce a measurable shift of the peak of the photoelectron momentum distribution, which allows the Wigner concept for the quasistatic tunneling time delay into the nonadiabatic domain. Expand
Exit point in the strong field ionization process
The concept of the exit point in the tunneling regime, which has long been assumed for the description of strong field ionization, is justified by the analysis. Expand
