DESCRIPTION:Brilliant\, ultrashort\, and coherent X-ray free-electron laser
  (FEL) pulses allow for investigation of dynamics at the inherent time and
  length scale of atoms which I will illustrate at the example of recent da
 ta taken in the so-called hidden phase of the Van der Waals material 1T-Ta
 S<sub>2</sub>. However\, currently missing at X-ray FELs are sequences of 
 phase-locked pulses\, desirable for time-domain correlation spectroscopies
  and coherent quantum control. In this seminar\, I will also present a sch
 eme to generate sub-femtosecond\, phase-locked X-ray pulse pairs with up t
 o 100 fs delay. This enables time-domain interferometry\, such as the X-ra
 y analog of the ubiquitous Fourier transform infrared spectrometer or reso
 nant inelastic X-ray scattering\, and\, more generally\, all of nonlinear 
 and quantum optics requiring coherent copies of beams. S. Reiche\, G. Knop
