Since the discovery of electron-wave duality, electron scattering instrumentation has
developed into a powerful array of techniques for revealing the atomic structure of matter …

One of the great dream experiments in Science is to directly observe atomic motions as they
occur. Femtosecond electron diffraction provided the first'light'of sufficient intensity to …

With the recent advances in ultrabright electron and x-ray sources, it is now possible to
extend crystallography to the femtosecond time domain to literally light up atomic motions …

Macroscopic quantum phenomena such as high-temperature superconductivity, colossal
magnetoresistance, ferrimagnetism and ferromagnetism arise from a delicate balance of …

Active optical control over matter is desirable in many scientific disciplines, with prominent
examples in all-optical magnetic switching,, light-induced metastable or exotic phases of …

The interaction of ultra-fast sub-picosecond laser pulses with solids is a very broad area of
research. The boundaries for research fields covered by this review are defined as follows. A …

During the past 50 years ion beam technologies have been proven to be powerful tools in
the continuously growing field of materials science. Ion beams are used for tailoring the …

We demonstrate the compression of 95 keV, space-charge-dominated electron bunches to
sub-100 fs durations. These bunches have sufficient charge (200 fC) and are of sufficient …

The extreme electro-optical contrast between crystalline and amorphous states in phase-
change materials is routinely exploited in optical data storage and future applications …

One of the grand challenges in chemistry has been to directly observe atomic motions
during chemical processes. The depiction of the nuclear configurations in space-time to …
