The role of spatiotemporal couplings in harmonic vortex generation
C. Granados, Bikash K. Das, M. Ciappina +1
We explore the impact of spatiotemporal couplings (STCs) on high-order harmonic generation (HHG) driven by spatiotemporal vortex beams. Our investigation demonstrates how STCs shap…

Attosecond vortices in semiconductor materials
C. Granados, B. Kumar Das, Christian Heide +2
We present the first theoretical results on the generation of short-wavelength attosecond vortex beams in semiconductors through their interactions with an intense Laguerre-Gauss b…
