Abstract 2D layered materials (2DLMs) are a subject of intense research for a wide variety of
applications (eg, electronics, photonics, and optoelectronics) due to their unique physical …

X-ray crystallography has been central to the development of many fields of science over the
past century. It has now matured to a point that as long as good-quality crystals are …

The roles of energy, momentum and orbital angular momentum conservation in high-
harmonic generation were studied in the past. Here, we explore the role of spin angular …

We demonstrate, to our knowledge, the first bright circularly polarized high-harmonic beams
in the soft X-ray region of the electromagnetic spectrum, and use them to implement X-ray …

Light–electron interaction is the seminal ingredient in free-electron lasers and dynamical
investigation of matter. Pushing the coherent control of electrons by light to the attosecond …

We present a theoretical study of high-order harmonic generation (HHG) and propagation
driven by an infrared field carrying orbital angular momentum (OAM). Our calculations unveil …

Nonlinear optics is of crucial importance in several fields of science and technology with
applications in frequency conversion, entangled‐photon generation, self‐referencing of …

High-energy phase-stable sub-cycle mid-infrared pulses can provide unique opportunities to
explore phase-sensitive strong-field light–matter interactions in atoms, molecules and solids …

Mid-infrared ultrashort high energy laser sources are opening up new opportunities in
science, including keV-class high harmonic generation and monoenergetic MeV-class …

Sources of short wavelength radiation with femtosecond to attosecond pulse durations, such
as synchrotrons or free electron lasers, have already made possible numerous, and will …
