A New Twist on Astigmatic Transformation: Beyond Laguerre-Gaussian Beams
Gabriela Flores-Cova, Bikash Kumar Das, Carmelo Rosales-Guzman +2
Astigmatic transformation is widely used to convert the azimuthal phase structure of Laguerre-Gaussian vortex beams into intensity patterns from which the topological charge can be…

Field-driven helicity in solid-state high-harmonic generation
Carlos Batista, Jean Paul Menotti, Dasol Kim +4
The polarization state of light plays a central role in strong-field light--matter interactions and is widely used to probe electronic structure in solids via high-order harmonic g…

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…
