Attosecond Path Qubits in High-Harmonic Generation: Classical Dephasing and Trace-Out Decoherence
A. Marchisio, C. Granados, M. F. Ciappina +1
High-harmonic generation (HHG) is governed by interference between electron trajectories. We propose that the dominant short and long trajectories define an experimentally addressa…
Single photon zeptosecond interferometry
Geoffrey R. Harrison, Tobias Saule, R. Esteban Goetz +6
We demonstrate the generation of a train of attosecond XUV pulses that are in a superposition of wavefront states. Such superposition yields a high precision, self-referencing, com…
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…
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…
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…
