Driven by applications in chemical sensing, biological imaging and material
characterisation, Raman spectroscopies are attracting growing interest from a variety of …

Abstract The EISCAT (European Incoherent SCATer) Scientific Association has provided
versatile incoherent scatter (IS) radar facilities on the mainland of northern Scandinavia (the …

We show analytically and through three-dimensional particle-in-cell simulations that
nonlinear wakefields driven by Laguerre-Gaussian laser pulses can lead to hollow electron …

Abstract Twisted Laguerre–Gaussian lasers, with orbital angular momentum and
characterized by doughnut-shaped intensity profiles, provide a transformative set of tools …

We theoretically demonstrate for the first time that a single free electron in circular or spiral
motion emits twisted photons carrying well-defined orbital angular momentum along the axis …

When a relativistic laser pulse with a high photon density interacts with a specially tailored
thin foil target, a strong torque is exerted on the resulting spiral-shaped foil plasma, or “light …

Spatiotemporal control refers to a class of optical techniques for structuring a laser pulse
with coupled spacetime-dependent properties, including moving focal points, dynamic spot …

Orbital angular momentum (OAM) conservation plays an important role in sha** and
controlling structured light with nonlinear optics. The OAM of a beam originating from three …

Spintronics and valleytronics are emerging quantum electronic technologies that rely on
using electron spin and multiple extrema of the band structure (valleys), respectively, as …

The inverse Faraday effect is usually associated with circularly polarized radiation; here, we
show that it can also occur for linearly polarized radiation. The quasistatic axial magnetic …
