characterisation, Raman spectroscopies are attracting growing interest from a variety of …

Vortex states of photons, electrons, and other particles are non-plane-wave solutions of the
corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic …

The recent prediction and subsequent creation of electron vortex beams in a number of
laboratories occurred after almost 20 years had elapsed since the recognition of the physical …

Traditional photonuclear reactions primarily excite giant dipole resonances, making the
measurement of isovector giant resonances with higher multipolarities a great challenge. In …

Optical vortices are currently one of the most intensively studied topics in optics. These light
beams, which carry orbital angular momentum (OAM), have been successfully utilized in the …

The orbital angular momentum (OAM) of light has attracted a great amount of interest in
recent times, due to the wide variety of applications it has made possible. Generally, the …

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

There is urgent need to develop new acceleration techniques capable of exceeding
gigaelectron-volt-per-metre (GeV m− 1) gradients in order to enable future generations of …

Infrared and visible light beams carrying orbital angular momentum (OAM) are currently
thoroughly studied for their extremely broad applicative prospects, among which are …
