Observation of light driven band structure via multi-band high harmonic spectroscopy
Ayelet J. Uzan-Narovlansky, Álvaro Jiménez-Galán, Gal Orenstein +8
Intense light-matter interactions have revolutionized our ability to probe and manipulate quantum systems at sub-femtosecond time scales, opening routes to all-optical control of e…
Chiral topological light for detecting robust enantio-sensitive observables
Nicola Mayer, David Ayuso, Piero Decleva +4
The topological response of matter to electromagnetic fields is a property in high demand in materials design and metrology due to its robustness against noise and decoherence, sti…
A Real-Space Perspective on Dephasing in Solid-State High Harmonic Generation
Graham G. Brown, Álvaro Jiménez-Galán, Rui E. F. Silva +1
We develop and demonstrate a fully real-space perspective on HHG in crystals. Due to Wannier-Stark localization induced on sub-cycle timescales in the presence of a strong field, r…
Polarization-Shaped Strong Field Control over Valley Polarization with Mid-IR Light
Igor Tyulnev, Julita Poborska, Álvaro Jiménez-Galán +4
We induce control over valley polarization with a polarization-shaped mid-infrared light field. The polarization state of the trefoil-shaped pump fields is measured by high harmoni…
High-Harmonic Spectroscopy of Coherent Lattice Dynamics in Graphene

High-harmonic spectroscopy of solids is a powerful tool, which provides access to both electronic structure and ultrafast electronic response of solids, from their band structure a…
Giant chiro-optical response in high harmonic generation
David Ayuso, Andres F. Ordonez, Piero Decleva +2
High harmonic generation (HHG) records the ultrafast electronic response of matter to light, encoding key properties of the interrogated quantum system, such as chirality. The firs…
Sub-cycle valleytronics: control of valley polarization using few-cycle linearly polarized pulses
Álvaro Jiménez-Galán, Rui Silva, Olga Smirnova +1
So far, selective excitation of a desired valley in the Brillouin zone of a hexagonal two-dimensional material has relied on using circularly polarized fields. We theoretically dem…
