      abstract     = {We propose a new approach based on an all-optical set-up
                      for generating relativistic polarized electron beams via
                      vortex Laguerre-Gaussian (LG) laser-driven wakefield
                      acceleration. Using a pre-polarized gas target, we find that
                      the topology of the vortex wakefield resolves the
                      depolarization issue of the injected electrons. In full
                      three-dimensional particle-in-cell simulations,
                      incorporating the spin dynamics via the Thomas-Bargmann
                      Michel Telegdi equation, the LG laser preserves the electron
                      spin polarization by more than $80\%$ while assuring
                      efficient electron injection. The method releases the limit
                      on beam flux for polarized electron acceleration and
                      promises more than an order of magnitude boost in peak flux,
                      as compared to Gaussian beams. These results suggest a
                      promising table-top method to produce energetic polarized
                      electron beams.},
