Scanning transmission electron microscopy (STEM) has emerged as a uniquely powerful
tool for structural and functional imaging of materials on the atomic level. Driven by …

In the last three decades, light's orbital angular momentum (OAM) has been of great interest
because it has unique characteristics that make it sought after in many research fields …

Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in
both applied and fundamental science. Continuous-wave electron vortex beams are …

In the past decade, optical orbital angular momentum (OAM) has entered the field of
plasmonics in the form of surface-confined vortices, generating vast interest. Here we give …

Chirality is a phenomenon with widespread relevance in fundamental physics, material
science, chemistry, optics, and spectroscopy. In this work, we show that a free electron can …

Temporally shaping the density of electron beams using light forms the basis for a wide
range of established and emerging technologies, including free-electron lasers and …

First results on the experimental realisation of a 2× 2 programmable phase plate for
electrons are presented. The design consists of an array of electrostatic elements that …

The component of orbital angular momentum (OAM) in the propagation direction is one of
the fundamental quantities of an electron wave function that describes its rotational …

A nuclear excitation following the capture of an electron in an empty orbital has been
recently observed for the first time. So far, the evaluation of the cross section of the process …

Electrons have played a significant role in the development of many fields of physics during
the last century. The interest surrounding them mostly involved their wave-like features …
