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…
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 a central problem for enabling optoelectronic applications based on topological physics, which is of fundamental concern fo…
Second-quantized numerical simulations of tunable entanglement in quantum high harmonic generation
Sebastián de-la-Peña, Heiko Appel, Angel Rubio +1
Quantum high-harmonic generation (HHG) is a prominent and growing field of research with potential capabilities of providing high photon-number entangled states of light. However,…
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…
