| The recent successes in generating femto-/attosecond flashes of x-ray light is only the first step towards measuring and understanding quantum properties of atoms and molecules on ultrashort time scales. The second necessary ingredient is the invention and application of dedicated time-resolved spectroscopic techniques and methods that can effectively be employed in the XUV and x-ray spectral domains to extract information by suitably set-up experiments. In this talk, we shall focus our discussion on this latter aspect, presenting several emerging spectroscopy methods that may become important tools in future time-resolved x-ray science. Moreover, we will discuss laser and XUV pulse shaping techniques for quantum control applications. Designing specific initial time-dependent states (e.g. specific molecular reaction pathways) with a shaped pump pulse could be interesting for future x-ray-imaging studies of molecular structural dynamics. |
