We find spectra at amplification levels extending over 4 orders of magnitude until saturation [...] OpenAccess: PDF PDF (PDFA); 2017-08-2910:24 [PUBDB-2017-10018] Journal Article et al Creating stable Floquet–Weyl semimetals by laser-driving of 3D Dirac materials Nature Communications 8, 13940 (2017) [10.1038/ncomms13940]   Tuning and stabilizing topological states, such as Weyl semimetals, Dirac semimetals or topological insulators, is emerging as one of the major topics in materials science. Periodic driving of many-body systems offers a platform to design Floquet states of matter with tunable electronic properties on ultrafast timescales.

We present high spectral resolution data on stimulated electronic x-ray Raman scattering in a gas sample of neon using a self-amplified spontaneous emission x-ray free-electron laser.
