Free-electron lasers produce extremely brief, coherent, and bright laser-like photon pulses
that allow to image matter at atomic resolution and at timescales faster than the …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

Warm dense matter (WDM)—an exotic state of highly compressed matter—has attracted
increased interest in recent years in astrophysics and for dense laboratory systems. At the …

The study of structure, thermodynamic state, equation of state (EOS) and transport properties
of warm dense matter (WDM) has become one of the key aspects of laboratory astrophysics …

We present the first highly resolved measurements of the plasmon spectrum in an ultrafast
heated solid. Multi-keV x-ray photons from the Linac Coherent Light Source have been …

The matter in extreme conditions end station at the Linac Coherent Light Source (LCLS) is a
new tool enabling accurate pump–probe measurements for studying the physical properties …

In this paper, we discuss some of the key challenges in the study of time-dependent
processes and non-equilibrium behaviour in warm dense matter. We outline some of the …

Based on high quality surgery and scientific data, scientists and surgeons are committed to
protecting patients as well as healthcare staff and hereby provide this Guidance to address …

We present simulations using finite-temperature density-functional-theory molecular
dynamics to calculate the dynamic electrical conductivity in warm dense aluminum. The …

The charged environment within a dense plasma leads to the phenomenon of ionization-
potential depression (IPD) for ions embedded in the plasma. Accurate predictions of the IPD …
