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…
Carrier-Envelope Phase Control of Orbital Angular Momentum in Solid-State High-Harmonic Generation
Camilo Granados, Rajaram Shrestha, Bikash Kumar Das +5
High-order harmonic generation (HHG) driven by optical vortices is a powerful route to produce structured light in different spectral regions. The nonlinear process transfers orbit…
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…
Fluctuation-induced symmetry breaking in high harmonic generation for bicircular quantum light
Philipp Stammer, Camilo Granados, Javier Rivera-Dean
Symmetries are ubiquitous in physics and play a pivotal role in light-matter interactions, where they determine the selection rules governing allowed atomic transitions and define…
Twisting harmonics: Transfer of orbital angular momentum in solid-state high-harmonic generation
Debobrata Rajak, Bikash Kumar Das, Rajaram Shrestha +7
Although solid-state platforms underpin modern electronics, little is known about how intense ultrashort light pulses carrying orbital angular momentum (OAM) interact with solids.…
Sculpting ultrafast mid-infrared light for solid-state high harmonic generation
Camilo Granados, Bálint Kiss, Eric Cormier +6
The ability to sculpt light in space, time, and polarization has revolutionized studies of light-matter interaction and enabled breakthroughs in optical communication, imaging, and…
High Harmonic Spectroscopy from Lower-Order to Higher-Order Topological Insulators
Bryan Lorenzo, Carlos Batista, Milad Jangjan +7
Over the past decades, high-harmonic spectroscopy (HHS) has emerged as a powerful tool for all-optical probing of topological properties of solids. There are outstanding questions…
