Ultrashort laser pulses are unique tools to trigger and probe the fastest charge dynamics in
matter, allowing the investigation of fundamental physical phenomena with unprecedented …

Optical interactions are governed by both spin and angular momentum conservation laws,
which serve as a tool for controlling light–matter interactions or elucidating electron …

Quantum information science and intense laser-matter interaction are two apparently
unrelated fields. Here, we introduce the notion of quantum information theory to intense …

High harmonics generated by counter-rotating laser fields at the fundamental and second
harmonic frequencies have raised important interest as a table-top source of circularly …

High-order harmonic generation stands as a unique nonlinear optical up-conversion
process, mediated by a laser-driven electron recollision mechanism, which has been shown …

We report on a method to generate extreme ultraviolet vortices from high-order harmonic
generation with two-color counter-rotating Laguerre-Gaussian (LG) beams that carry a well …

We summarize the development of high harmonic generation (HHG) with linearly polarized
Laguerre–Gaussian (LG) beams and their superpositions to explain the non-perturbative …

The application of strong bi-elliptically polarized laser fields to the generation of high-order
harmonics in organic molecules offers exceptional opportunities for chiral recognition and …

If the time evolution of a quantum state leads back to the initial state, a geometric phase is
accumulated that is known as the Berry phase for adiabatic evolution or as the Aharonov …

The generation of high-order harmonics in a medium of chiral molecules driven by intense bi-
elliptical laser fields can lead to strong chiroptical response in a broad range of harmonic …
