Quantum complementarity states that particles, e.g. electrons, can exhibit wave-like properties such as diffraction and interference upon propagation. \textit{Electron waves} defined by a helical wavefront are referred to as twisted electrons~\cite{uchida:10,verbeeck:10,mcmorran:11}. These electrons are also characterised by a quantized and unbounded magnetic dipole moment parallel to their propagation direction, as they possess a net charge of $-|e|$~\cite{bliokh:07}. When interacting with… Expand

How electron wave functions can be imprinted with quantized phase vortices in analogous ways to twisted light, demonstrating that charged particles with non-zero rest mass can possess orbital angular momentum in free space is discussed. Expand
Theory and applications of free-electron vortex states
Abstract Both classical and quantum waves can form vortices : entities with helical phase fronts and circulating current densities. These features determine the intrinsic orbital angular momentumExpand

Imaging the dynamics of free-electron Landau states
The real-space observation of Landau states and the internal rotational dynamics of free electrons are reported and it is observed that Landau modes with different azimuthal quantum numbers belong to three classes, which are characterized by rotations with zero, Larmor and cyclotron frequencies, respectively.

Generation of electron beams carrying orbital angular momentum
The generation of an electron beam with a phase singularity propagating in free space is reported by passing a plane electron wave through a spiral phase plate constructed naturally from a stack of graphite thin films. Expand

We show that the well-known Cerenkov effect contains new phenomena arising from the quantum nature of charged particles. The Cerenkov transition amplitudes allow coupling between the charged particleExpand

We examine the propagation of the recently-discovered electron vortex beams in a longitudinal magnetic field. We consider both the Aharonov-Bohm configuration with a single flux line and the LandauExpand
Production and application of electron vortex beams
This technique is a reproducible method of creating vortex electron beams in a conventional electron microscope, and it is demonstrated how they may be used in electron energy-loss spectroscopy to detect the magnetic state of materials and describe their properties. Expand
Local orbital angular momentum revealed by spiral-phase-plate imaging in transmission-electron microscopy
The orbital angular momentum (OAM) of light and matter waves is a parameter that is getting increasingly more attention over the past couple of years. Beams with a well defined OAM, the so-calledExpand
Entanglement of the orbital angular momentum states of photons
This work demonstrates entanglement involving the spatial modes of the electromagnetic field carrying orbital angular momentum, which provides a practical route to entangled states that involves many orthogonal quantum states, rather than just two Multi-dimensional entangled states could be of considerable importance in the field of quantum information, enabling, for example, more efficient use of communication channels in quantum cryptography.

Experimental realization of the Ehrenberg-Siday thought experiment
In 1949, at the end of a paper dedicated to the concept of the refractive index in electron optics, Ehrenberg and Siday noted that wave-optical effects will arise from an isolated magnetic field evenExpand
Semiclassical dynamics of electron wave packet states with phase vortices.
S semiclassical higher-order wave packet solutions of the Schrödinger equation with phase vortices are considered and the magnetic-monopole Berry curvature appears in momentum space, which results in a spin-orbit-type interaction and a Berry/Magnus transverse force acting on the wave packet. Expand
