Geometry-Driven Resonance and Localization of Light in Fractal Phase Spaces
L. Yıldız, D. Kaykı, M. F. Ciappina
Geometry can fundamentally govern the propagation of light, independent of material constraints. Here, we demonstrate that a fractal phase space, endowed with a non-Euclidean, scal…
Optical Vortices: Revolutionizing the field of linear and nonlinear optics
Bikash K. Das, Camilo Granados, Marcelo F. Ciappina
Light is the fundamental medium through which we perceive the world around us. In the modern era, light can not only be used in its raw form but can also be used as a versatile too…
A spatiotemporal couplings perspective on harmonic vortices generation
C. Granados, B. Kumar Das, M. F. Ciappina +1
The interaction of light with matter serves as a fundamental tool for probing material properties across a wide range of energy regimes. Recent breakthroughs in tailoring the topol…
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…
