  • Linearly polarized orbital angular momentum-carrying hard X-ray beams are induced using spiral Fresnel zone plates. By sending the hard X-ray beams to disordered enantiopure molecular complexes, the helicity-dependent and chiral-sensitive signal is obtained.

  • Using hard X-rays for transient grating (TG) spectroscopy, fundamental excitations can be followed with femtosecond temporal and nanometer spatial resolution, selecting momenta, chemical elements and their chemical environment. The authors demonstrate the first experiment of all X-ray TG on an amorphous film of FeGd and on a silicon single crystal.
