  • Charge-density-wave (CDW) materials are an ideal platform for exploring the complex interactions between lattice dynamics and quantum order. Here, the authors use time- and angle-resolved photoemission spectroscopy to demonstrate that CDW gap closure in VTe2 is driven by incoherent processes, providing a universal framework for light-induced phase transitions in CDW systems.

  • This study presents a method to create nanoscale polarization transient gratings in the EUV range. Unlike intensity gratings, it reduces thermal effects, revealing hidden material dynamics. This enables new insights in chiral materials and ultrafast magnetism.

  • 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.

  • A four-wave mixing technique is developed in the hard X-ray range. A diamond phase grating in an X-ray beam path creates a periodic excitation pattern on a sample via the Talbot effect. The response of the periodic excitation is probed by an optical pulse.
