Contrasting ultrafast light-driven electron-hole interaction dynamics in monolayer MoS and metallic NbSe
Aday Cárdenas, Rui E. F. Silva, Álvaro Jiménez-Galán
We study strong-field driven ultrafast dynamics and high-harmonic generation (HHG) in monolayer 2H-NbSe and compare them with those of monolayer 2H-MoS by solving the multi…
Effects of Zero-Point Motion in the High Harmonic Generation Spectrum of Solids
Aday Cárdenas, David N. Purschke, Graham G. Brown +3
The interpretation of high-harmonic generation (HHG) in solids typically relies on phenomenological dephasing times far shorter than what is expected from microscopic scattering pr…
Ultrafast valleytronic logic operations
Francesco Gucci, Eduardo B. Molinero, Mattia Russo +8
Information processing currently reaches speeds as high as 800 GHz. However, the underlying transistor technology is quickly approaching its fundamental limits and further progress…
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…
Deep neural networks for high harmonic spectroscopy in solids
Nikolai D. Klimkin, Álvaro Jiménez-Galán, Rui E. F. Silva +1
Neural networks are a prominent tool for identifying and modeling complex patterns, which are otherwise hard to detect and analyze. While machine learning and neural networks have…
High harmonic spectroscopy of disorder-induced Anderson localization
Adhip Pattanayak, Á. Jiménez-Galán, Misha Ivanov +1
Exponential localization of wavefunctions in lattices, whether in real or synthetic dimensions, is a fundamental wave interference phenomenon. Localization of Bloch-type functions…
Light-Induced Valleytronics in Pristine Graphene
M. S. Mrudul, Álvaro Jiménez-Galán, Misha Ivanov +1
Electrons in two-dimensional hexagonal materials have valley degree of freedom, which can be used to encode and process quantum information. The valley-selective excitations, gover…
Lightwave topology for strong-field valleytronics
Á. Jiménez-Galán, R. E. F. Silva, O. Smirnova +1
Modern light generation technology offers extraordinary capabilities for sculpting light pulses, with full control over individual electric field oscillations within each laser cyc…
Multi-Band Petahertz Currents Resolved via High Harmonic Generation Spectroscopy
Ayelet Julie Uzan, Gal Orenstein, Álvaro Jiménez-Galán +13
Strong field driven electric currents in condensed matter systems open new frontiers in petahertz electronics. In this regime new challenges arise as the role of the band structure…
Control of helicity of high-harmonic radiation using bichromatic circularly polarized laser fields
Gopal Dixit, Álvaro Jiménez-Galán, Lukas Medišauskas +1
High-harmonic generation in two-colour () counter-rotating circularly polarised laser fields opens the path to generate isolated attosecond pulses and attosecond pulse trains…
Control of attosecond light polarization in two-color bi-circular fields
Álvaro Jiménez-Galán, Nick Zhavoronkov, David Ayuso +6
We develop theoretically and confirm both numerically and experimentally a comprehensive analytical model which describes the propensity rules in the emission of circularly polariz…
