Electrochemical and electrocatalytic processes are of key importance for the transition to a
sustainable energy supply as well as for a wide variety of other technologically relevant …

Featured Application This article describes the layout of the European XFEL, a soft and hard
X-ray free-electron laser user facility starting operation in 2017. Emphasis is put on the …

We report on the nonequilibrium dynamics of the electronic structure of the layered
semiconductor Ta 2 NiSe 5 investigated by time-and angle-resolved photoelectron …

We review current progress with respect to ultrafast, atomic-scale resolution X-ray scattering
studies of materials. In the last decade, advances in sources and techniques have opened …

We analyze Cooper pairing instabilities in strongly driven electron-phonon systems. The
light-induced nonequilibrium state of phonons results in a simultaneous increase of the …

The significant progress in angle-resolved photoemission spectroscopy (ARPES) in last
three decades has elevated it from a traditional band mapping tool to a precise probe of …

The interaction of many-body systems with intense light pulses may lead to novel emergent
phenomena far from equilibrium. Recent discoveries, such as the optical enhancement of …

Femtosecond light-induced phase transitions between different macroscopic orders provide
the possibility to tune the functional properties of condensed matter on ultrafast timescales …

Particle accelerators are invaluable discovery engines in the chemical, biological and
physical sciences. Characterization of the accelerated beam response to accelerator input …

Here, we photoinduce and directly observe with x-ray scattering an ultrafast enhancement of
the structural long-range order in the archetypal Mott system V 2 O 3. Despite the ultrafast …
