Research on isolated attosecond pulses (IAPs) based on high-order harmonic generation
changed substantially around 2010. Before then, the Ti: sapphire laser was the de facto …

Recent progress in high power ultrafast short-wave and mid-wave infrared lasers has
enabled gas-phase high harmonic generation (HHG) in the water window and beyond, as …

The motion of electrons in the microcosm occurs on a time scale set by the atomic unit of
time—24 attoseconds. Attosecond pulses at photon energies corresponding to the …

Photoinduced quantum dynamics in molecules have hierarchical temporal structures with
different energy scales that are associated with electron and nuclear motions. Femtosecond …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

This work demonstrates nanoscale magnetic imaging using bright circularly polarized high-
harmonic radiation. We utilize the magneto-optical contrast of worm-like magnetic domains …

We present a detailed discussion of the electronic band structure and excitonic dispersion of
hexagonal boron nitride (hBN) in the single layer configuration and in three bulk polymorphs …

As a compact and burgeoning alternative to synchrotron radiation and free-electron lasers,
high harmonic generation (HHG) has proven its superiority in static and time-resolved …

We theoretically introduce the fundamentally fastest induction of a significant population and
valley polarization in a monolayer of a transition metal dichalcogenide (ie, MoS 2 and WS 2) …

Attosecond pulses in the soft x-ray (SXR) to water-window energy region offer the tools for
creating and studying target-specific localized inner-shell electrons or holes in materials …
