This review stands in the larger framework of functional materials by focussing on
heterostructures of rare-earth nickelates, described by the chemical formula RNiO 3 where R …

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 …

In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

Solid oxide cells (SOCs) have the potential to be the most efficient energy storage and
conversion systems. To minimize energy loss due to charge and mass transport associated …

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 …

The electronic structure of transition metal oxides featuring correlated electrons can be
rationalized within the Zaanen-Sawatzky-Allen framework. Following a brief description of …

Light fields at terahertz and mid-infrared frequencies allow for the direct excitation of
collective modes in condensed matter, which can be driven to large amplitudes. For …

Value-added chemical production via electrocatalysis is of great significance in green
chemical society, the industrialization of which, however, is restricted by its low profit …

Strong optical pulses at mid-infrared and terahertz frequencies have recently emerged as
powerful tools to manipulate and control the solid state and especially complex condensed …
