Ultrafast x-ray scattering
Our group is focusing on discovering and understanding the ultrafast properties of materials by designing the ultrafast x-ray scattering. Ultrafast x-ray scattering is a cutting-edge experimental technique that uses ultra-short pulses of X-ray radiation to probe the structural dynamics of materials on extremely fast timescales. With the development of ultrafast X-ray sources, such as free-electron lasers (FELs), it is now possible to capture the motions of atoms and molecules in real-time with sub-picosecond resolution. This technique has revolutionized the field of materials science, allowing researchers to study the atomic-scale mechanisms underlying a wide range of phenomena, including phase transitions, chemical reactions, and biological processes. By combining the power of X-ray diffraction and spectroscopy with the time resolution of ultrafast lasers, ultrafast X-ray scattering provides a powerful tool for unraveling the complex behavior of matter at the most fundamental level.
