Abstract

Recently discovered vortex electron waves carry a quantized amount of orbital angular momentum. Interacting them with gold nanoparticles supported on a thin membrane makes the particles rotate clockwise or anticlockwise with time depending on the sign of the orbital angular momentum of the electron vortex. This experiment opens possibilities to manipulate nanoparticles and study friction on the nanoscale.
