CONEXS: COllaborative NEtwork for X-ray Spectroscopy

点击翻译按钮获取中文摘要

Scientific breakthroughs are strongly associated with technological developments, which enable the measurement of matter to an increased level of detail. A prime example of this is the development of femtosecond lasers, which opened up the field of ultrafast spectroscopy. This had a huge impact on our understanding of chemical reactions, biological functions and phase transitions in materials owing to their ability to probe, in real-time, the nuclear motion within these different types of systems. A modern revolution is underway in X-ray science with the emergence of tools capable of delivering high-brilliance ultrashort pulses of X-rays. The UK, through the Diamond Light source, investment into the European X-FEL and world-leading research groups are at the forefront of these experimental endeavors. Crucially, the complicated nature and high information context of X-ray spectroscopic observables means that a strong synergy between experiment and theory is required. However, despite the development of new theoretical methods, the exploitation of the high level methods remains relatively uncommon resulting in the full potential of the experiments not being realised. This status-quo is unacceptable, and overcoming it is one of the primary objectives of the COllaborative NEtwork for X-ray Spectroscopy (CONEXS), which will bring together experimentalists and theoreticians working in this area to achieve new levels of understanding. From the perspective of the computational community, direct engagement with experimentalists can highlight theoretical challenges and act as a catalyst for the development of new methods. From the experimental community, direct engagement with theoreticians will provide expertise in the new theoretical developments providing new opportunities for data analysis.
