Recent advances in the generation of well-characterized subfemtosecond laser pulses have
opened up unpredicted opportunities for the real-time observation of ultrafast electronic …

The emerging application of attosecond techniques to molecular systems allows the role of
electronic coherence in the control of chemical reactions to be investigated. Prompt …

Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit
experiment has been frequently used for understanding different aspects of this fundamental …

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 …

We demonstrate a technique that uses high-order harmonic generation in molecules to
probe nuclear dynamics and structural rearrangement on a subfemtosecond time scale. The …

High-order harmonic generation (HHG) from atoms and molecules offers potential
application as a coherent ultrashort radiation source in the extreme ultraviolet and soft X-ray …

Molecular electronic states energetically below the highest occupied molecular orbital
(HOMO) should contribute to laser-driven high harmonic generation (HHG), but this behavior …

By analyzing accurate theoretical results from solving the time-dependent Schrödinger
equation of atoms in few-cycle laser pulses, we established the general conclusion that …

When molecules are subject to intense laser pulses, electrons can be detached, accelerated
and driven back to the molecule, resulting in electron–ion recollisions. Recolliding electrons …

Lobate features abutting massifs and escarpments in the middle latitudes of Mars have been
recognized in images for decades, but their true nature has been controversial, with …
