Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

Time-dependent density-functional theory (TDDFT) describes the quantum dynamics of
interacting electronic many-body systems formally exactly and in a practical and efficient …

Experimental advances with laser intensities above 1 TW/cm 2, with pulse durations
between roughly 50 and 5 fs, have led to the discovery of new atomic effects that include …

The theoretical description and the experimental methods and results for above-threshold
ionization (ATI) by few-cycle pulses are reviewed. A pulse is referred to as a few-cycle pulse …

When an atom or molecule is exposed to a short intense laser pulse, electrons that were
removed at an earlier time may be driven back by the oscillating electric field of the laser to …

Despite their broad implications for phenomena such as molecular bonding or chemical
reactions, our knowledge of multi-electron dynamics is limited and their theoretical …

The availability of few-cycle optical pulses opens a window to physical phenomena
occurring on the attosecond timescale. To take full advantage of such pulses, it is crucial to …

Time-dependent density-functional theory (TDDFT) extends the basic ideas of ground-state
density-functional theory (DFT) to the treatment of excitations and of more general time …

In recent years the use of high-order harmonic radiation to create and control events on
attosecond timescales has grown at a phenomenal rate. With the use of carrier-envelope …

In the context of strong field–matter interaction, an increasing number of phenomena has
been found to be not understood within the single-active-electron approximation. For such …
