Position, spin and orbital angular momentum of a relativistic electron
Konstantin Y. Bliokh, Mark R. Dennis, Franco Nori
Motivated by recent interest in relativistic electron vortex states, we revisit the spin and orbital angular momentum properties of Dirac electrons. These are uniquely determined b…
A random wave model for the Aharonov-Bohm effect
Alexander J H Houston, Martin Gradhand, Mark R Dennis
We study an ensemble of random waves subject to the Aharonov-Bohm effect. The introduction of a point with a magnetic flux of arbitrary strength into a random wave ensemble gives a…
Generation and Application of Bessel Beams in Electron Microscopy
Vincenzo Grillo, Jérémie Harris, Gian Carlo Gazzadi +6
We report a systematic treatment of the holographic generation of electron Bessel beams, with a view to applications in electron microscopy. We describe in detail the theory underl…
Relativistic Electron Vortex Beams: Angular Momentum and Spin-Orbit Interaction
Konstantin Y. Bliokh, Mark R. Dennis, Franco Nori
Motivated by the recent discovery of electron vortex beams carrying orbital angular momentum (AM), we construct exact Bessel-beam solutions of the Dirac equation. They describe rel…
Entangled topological features of light
J. Romero, J. Leach, B. Jack +4
We report the entanglement of topological features, namely, isolated, linked optical vortex loops in the light from spontaneous parametric down-conversion (SPDC). In three dimensio…
