Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

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 …

High harmonic emission occurs when an electron, liberated from a molecule by an incident
intense laser field, gains energy from the field and recombines with the parent molecular ion …

The transfer of charge at the molecular level plays a fundamental role in many areas of
chemistry, physics, biology and materials science. Today, more than 60 years after the …

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 …

Organic light-emitting diodes (OLEDs) show promise for applications as high-quality self-
emissive displays for portable devices such as cellular phones and personal organizers …

We present a computer package aimed at the simulation of the electron–ion dynamics of
finite systems, both in one and three dimensions, under the influence of time-dependent …

The study of chemical reactions on the molecular (femtosecond) timescale typically uses
pump laser pulses to excite molecules and subsequent probe pulses to interrogate them …

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 …

Generating attosecond pulses has required a radically different approach from previous
ultrafast optical methods. The technology of attosecond measurement, however, is built on …
