      abstract     = {Almost one and a half centuries ago, Abbe [Arch. Mikrosk.
                      Anat. 9, 413 (1873)] and shortly after Lord Rayleigh
                      [Philos. Mag. Ser. 5 8, 261 (1879)] showed that, when an
                      optical lens is illuminated by a plane wave, a
                      diffraction-limited spot with radius 0.61λ/sinα is
                      obtained, where λ is the wavelength and α is the semiangle
                      of the beam's convergence cone. However, spots with much
                      smaller features can be obtained at the focal plane when the
                      lens is illuminated by an appropriately structured beam.
                      Whereas this concept is known for light beams, here, we show
                      how to realize it for a massive-particle wave function,
                      namely, a free electron. We experimentally demonstrate an
                      electron central spot of radius 106 pm, which is more than
                      two times smaller than the diffraction limit of the
                      experimental setup used. In addition, we demonstrate that
                      this central spot can be structured by adding orbital
                      angular momentum to it. The resulting superoscillating
                      vortex beam has a smaller dark core with respect to a
                      regular vortex beam. This family of electron beams having
                      hot spots with arbitrarily small features and tailored
                      structures could be useful for studying electron-matter
                      interactions with subatomic resolution.},
