High-Harmonic Generation Probes Quantum Nuclear Fluctuations in Liquid Water
George Trenins, Nicolas Tancogne-Dejean, Angana Mondal +5
Nuclear quantum effects are essential for an accurate description of the hydrogen-bonded structure of liquid water, yet their spectroscopic signatures can be subtle and difficult t…
Composition-controlled optical fingerprints and anisotropy of self-trapped excitons in double perovskites
Simone Grillo, Offir Zachs Maishlos, Liya Koren +7
Double perovskites (DPs) offer a compositionally versatile platform for photocatalysis and optoelectronics, but their soft lattices favor strong exciton-phonon coupling and self-tr…
Phonon-mediated closing of topological Floquet gaps in graphene: Non-phenomenological analysis
Royi Ledermann, Rave Hanoch Saadon, Adam Herling +1
Floquet band engineering has been intensively studied for its potential to control material properties via laser driving. In particular, Floquet topological states have been measur…
Attosecond charge migration timescales are dominated by transition dipoles, not correlations
Km Akanksha Dubey, Ofer Neufeld
Attosecond charge migration (CM) is an ultrafast process occurring when a molecule is irradiated by ultrashort laser pulses, creating a localized hole. The hole propagates rapidly…
High-order correlations and ultrafast Wigner negativities in bright-squeezed-vacuum-driven high-harmonic generation
Sebastián de-la-Peña, Heiko Appel, Marcelo F. Ciappina +2
High-harmonic generation (HHG) is a prototypical strong-field process in which intense light drives matter to emit radiation at integer multiples of the driving frequency. Extendin…
Multidimensional attosecond clocking near Dirac cones in graphite
Daniel Kroeger, Anna Hassine, Eyal Uzner +5
Two-color high-harmonic spectroscopy is widely used to access sub-cycle electron dynamics and to retrieve harmonic timing information, including harmonic phases and attochirp acros…
Ultrafast spectroscopy and role of interlayer coupling in high harmonic generation from layered solids
Eyal Uzner, Ofer Neufeld
High harmonic generation (HHG) in solids has recently emerged as a powerful all-optical approach for probing material properties and ultrafast electron dynamics in quantum systems.…
Role of ultrafast electron-optical-phonon interactions in high harmonic generation from graphene
Adam Herling, Ofer Neufeld
High harmonic generation (HHG) is a widely explored process in solids, where intense lasers drive attosecond-to-femtosecond electron dynamics within bands, causing high-energy emis…
Double circular dichroism high harmonic spectroscopy: An ultrafast probe for topological photocurrents
Osamah Sufyan, Ofer Neufeld
Understanding optical responses of topological matter is central to optoelectronic applications, photocurrent control, and spectroscopy. Yet schemes for sensing ultrafast photocurr…
Pulse-duration-sensitive high harmonics and attosecond locally-chiral light from a chiral topological Weyl semimetal
Alba de las Heras, Ofer Neufeld, Angel Rubio
High harmonic generation (HHG) in solids results from an interplay between intraband acceleration and electron-hole recombination driven by a high-intensity laser pulse. Here, we t…
Ab-initio study of high harmonic generation from fullerenes: Multi-orbital effects, correlations, and size dependence
Km Akanksha Dubey, Ofer Neufeld
We study with ab-initio theory high harmonic generation (HHG) from a series of gas-phase fullerenes (from C to C, including isomers) under varying laser conditions (l…
