Orbital angular momentum (OAM) is a physical quantity representing a magnitude of orbital motion of an object. Recently, it has been recognized that a propagating wave in free space, such as photon, electron and neutron can similarly carry OAM. This OAM degree of freedom of electron beam has been attracting a great attention not only for physical interest but also for its potential applications. This article gives you an idea of what propagating waves carrying OAM are and reviews recent progress in researches of electron vortex beams.
