Recent progress in utilizing ultrafast light-matter interaction to control the macroscopic
properties of quantum materials is reviewed. Particular emphasis is placed on photoinduced …

The past decade has witnessed an explosion in the field of quantum materials, headlined by
the predictions and discoveries of novel Landau-symmetry-broken phases in correlated …

We present the first lasing results of SwissFEL, a hard X-ray free-electron laser (FEL) that
recently came into operation at the Paul Scherrer Institute in Switzerland. SwissFEL is a very …

The SwissFEL X-ray Free Electron Laser (XFEL) facility started construction at the Paul
Scherrer Institute (Villigen, Switzerland) in 2013 and will be ready to accept its first users in …

A new scientific frontier opened in 2009 with the start of operations of the world's first x-ray
free-electron laser (FEL), the Linac Coherent Light Source (LCLS), at SLAC National …

We present the development of the first ultrafast transmission electron microscope (UTEM)
driven by localized photoemission from a field emitter cathode. We describe the …

Ultrafast electron and X-ray imaging and spectroscopy are the basis for an ongoing
revolution in the understanding of dynamical atomic-scale processes in matter. The …

Many ultrafast solid phase transitions are treated as chemical reactions that transform the
structures between two different unit cells along a reaction coordinate, but this neglects the …

Laser-wakefield accelerators (LWFAs) were proposed more than three decades ago, and
while they promise to deliver compact, high energy particle accelerators, they will also …

Universality is a powerful concept, which enables making qualitative and quantitative
predictions in systems with extensively many degrees of freedom. It finds realizations in …
