Dynamical processes in out-of-equilibrium materials at extreme conditions

The principle aim of this project is to perform new ground breaking experiments in glass formers at extreme conditions and in a previously unexplored dynamical range by using X-ray Photon Correlation Spectroscopy (XPCS) at high energy and in combination with in-situ high pressure and high temperature devices. This takes benefits from the current EBS upgrade of ESRF which has revolutionized the XPCS technique thanks to a 100 times higher coherent flux with the extension into hard x-rays up to 25 keV. The knowledge of the relaxation processes occurring in glass formers and their evolution under applied constraints like pressure and temperature is important not only from the theoretical point of view, but also for technological applications as it may provide important receipes for improving their stability and properties during processing and operation. The extension of XPCS to studies at extreme conditions will be of interest of many scientist working in different fields.
