Electron vortex beams in a magnetic field: A new twist on landau levels and aharonov-bohm states

Bliokh, Konstantin; Schattschneider, P; Verbeeck, Jo; Nori, Franco

Description

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 Landau case of a uniform magnetic field. While stationary Aharonov-Bohm modes represent Bessel beams with flux- and vortex-dependent probability distributions, stationary Landau states manifest themselves as nondiffracting Laguerre-Gaussian beams. Furthermore, the Landau-state beams possess field- and...[Show more]
