Science under extreme conditions is a vibrant field of research. In the last ten years, many scientific breakthroughs have been achieved across fields ranging from Earth and planetary science to fundamental physics, chemistry and materials research, and extending into biophysics/biochemistry including questions concerning life and biological function under extreme conditions. In this context, “Matter at extreme pressures and temperatures” was one of the science drivers for the construction of low emittance 4th generation high-energy synchrotron sources and free electrons lasers. The outstanding performance of these new X-ray sources will surely have a profound impact in extreme conditions science and breakthroughs can be expected in various scientific areas. In particular, detailed structural, electronic and vibrational studies on much smaller sample volumes and on sub-ps time scales will become possible. Higher pressure (multi-Mbar) and temperature states which can be generated only in smaller volumes will be finally characterized. Transient processes under extreme strain rates will be seen. Submicron sample heterogeneities will also become accessible, down to the femtosecond time scale, with a deeper understanding of processes such as phase transitions and transport (diffusion, viscosity) under extreme conditions. New x-ray methods and sample geometries for diffraction and spectroscopy will be discussed. This micro-symposium aims at defining the current state-of-the-art at the existing synchrotron and XFEL facilities and discussing the new research opportunities that will emerge from the complementarity of these large instruments.
