Structured relativistic electron and neutron vortex beams in intense laser fields

Recent advances in technology and instrumentation have made it possible to generate vortex beams of electrons and neutrons with phase singularities at their cores, where the beam intensity is zero and the phase is undefined. These new types of beams, apart from the spin angular momentum, carry a quantized orbital angular momentum (OAM) along their axes of propagation resulting in a twisted wavefronts, pretty much like quantum tornadoes. The OAM of electron is capable of fundamentally altering the physics of beams and is already being used for application purposes in electron microscopy. [mehr]
