We predict a significant delay of two-electron photoemission from the helium atom after absorption of an attosecond XUV pulse. We establish this delay by solving the time-dependent Schrödinger equation and by subsequently tracing the field-free evolution of the two-electron wave packet. This delay can also be related to the energy derivative of the phase of the complex double-photoionization (DPI) amplitude which we evaluate by using the convergent close-coupling method. Our observations… 

Double ionization probed on the attosecond timescale

Double ionization following the absorption of a single photon is one of the most fundamental processes requiring interaction between electrons(1-3). Information about this interaction is usually

Theory of attosecond time delay in double photoionization of noble gas atoms

We present a theoretical interpretation of attosecond time-delays in double photoionization (DPI) measured in XUV-pump and IR-probe experiments using coincidence detection. The so-called Wigner time

Probing time-ordering in two-photon double ionization of helium on the attosecond time scale

We show that time ordering underlying time-dependent quantum dynamics is a physical observable accessible by attosecond streaking. We demonstrate the extraction of time ordering for the prototypical

Shake-Off Process in Non-Sequential Single-Photon Double Ionization of Closed-Shell Atomic Targets

Amusia and Kheifets in 1984 introduced a Green’s function formalism to describe the effect of many-electron correlation on the ionization spectra of atoms. Here, we exploit this formalism to model

Probing single-photon ionization on the attosecond time scale.

The determination of photoemission time delays requires taking into account the measurement process, involving the interaction with a probing infrared field, and this contribution can be estimated using a universal formula and is found to account for a substantial fraction of the measured delay.

Delay in atomic photoionization.

It is argued that the extreme ultraviolet pulse alone cannot produce such a large time delay and it is the streaking IR field that is most likely responsible for this effect.

Use of electron correlation to make attosecond measurements without attosecond pulses.

To reconstruct the dynamics of correlated two-electron ionization with attosecond precision, not only classical time and energy correlation, but also entanglement between the two electrons is used.

Ultrafast metrology reveals a 20-attosecond delay between photoemission from different electronic orbitals in neon atoms and theoretical models refined with the help of attosecond timing metrology may provide insight into electron correlations and allow the setting of the zero of time in atomic-scale chronoscopy with a precision of a few attose Cond.

Attosecond Ionization and Tunneling Delay Time Measurements in Helium

The technique relies on establishing an absolute reference point in the laboratory frame by elliptical polarization of the laser pulse, from which field-induced momentum shifts of the emergent electron can be assigned to a temporal delay on the basis of the known oscillation of the field vector.
