Attosecond chronoscopy enables the exploration of correlated electron dynamics in real
time. One key observable of attosecond physics is the determination of “time zero” of …

High angular momentum partial waves are indispensable in the numerical calculations of
the time-dependent Schrödinger equation (TDSE) for the interaction between atoms and …

Double ionization of helium by a single intense (above 10 18 W/cm 2) linearly polarized
extreme ultraviolet laser pulse is studied by numerically solving the full-dimensional time …

We theoretically investigate few-photon double ionization of helium in intense XUV laser
fields by numerically solving the time-dependent Schrödinger equation. Our results show …

We theoretically and experimentally investigate the photon momentum transfer in single-
photon double ionization of helium at various large photon energies. We find that the …

We have observed the laser-assisted dynamic interference in the electron spectra triggered
by attosecond pulse trains. The fingerprints of finer interference fringes, much smaller than …

As a step toward the full ab initio description of two-photon double ionization processes, we
present a finite-pulse version of the virtual-sequential model for polyelectronic atoms. The …

We investigate multiphoton double ionization of helium by ultrashort XUV pulses involving
up to 5 XUV photons by numerically solving the time-dependent Schrödinger equation for …

We develop a realistic one-dimensional (1D) model for describing the direct (nonsequential)
two-photon double ionization of an atomic system. The model is used to calculate …

Double ionization of a model helium system by intense extreme ultraviolet laser pulses is
investigated by solving the time-dependent Schrödinger equation and extracting the …
