Abstract: X-rays provide a unique spectroscopic view of molecules and materials, from an element-specific and orbital-selective frame of reference. Femtosecond and attosecond X-ray and extreme ultraviolet pulses (XUV) are used to probe curve crossings and conical intersections in molecules, electron and hole carriers in solids, coherent phonon motions, and core hole excitons, revealing breathtaking 'movies' of novel, ultrashort dynamical processes.
