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 …

Recollision processes are fundamental to strong-field physics and attoscience, thus models
connecting recolliding trajectories to quantum amplitudes are a crucial part in furthering …

Optical activity (OA) is the rotation of the polarization orientation of the linearly polarized light
as it travels through certain materials that are of mirror asymmetry, including gases or …

We demonstrate experimentally an efficient electron axicon lens using a magnetic vortex.
We show that naturally occurring magnetic vortices with circular magnetic moment …

Signal-to-noise ratio and spatial resolution are quantitatively analysed in the context of in-
line (propagation based) X-ray phase-contrast imaging. It is known that free-space …

We study a matter wave double-slit experiment with unequal aperture widths in order to
evaluate the effect of the Gouy phase on the visibility/predictability. While the predictability …

This work presents a study on the phase-and group-velocity variations of focused, pulsed
Gaussian beams during the propagation through the focal region along the optical axis. In …

Light is an essential element for life, and not just by reason of being the primary energy
source of Earth's flora, and through plants and unicellular organisms of its whole fauna, but …

We study the effect of the Gouy phase in Bohr's complementarity principle. We propose a
doubleslit experiment with unequal aperture widths for which we can measure the particle …

Singularities in wave fields, such as phase vortices, are of substantial interest for light optics,
matter waves and x-ray optics. New theoretical insights [1] and cutting edge nanofabrication …
