Manipulating Twisted Electron Beams [PDF]
A theoretical description of vortex electrons interacting with electric and magnetic fields is presented, based on Lorentz transformations. The general dynamical equations of motion of a twisted electron with intrinsic orbital angular momentum in an external field is derived.
