      abstract     = {We demonstrate that an important quantum material WTe2
                      exhibits a new type of geometry-induced spin filtering
                      effect in photoemission, stemming from low symmetry that is
                      responsible for its exotic transport properties. Through the
                      laser-driven spin-polarized angle-resolved photoemission
                      Fermi surface mapping, we showcase highly asymmetric spin
                      textures of electrons photoemitted from the surface states
                      of WTe2. Such asymmetries are not present in the initial
                      state spin textures, which are bound by the time-reversal
                      and crystal lattice mirror plane symmetries. The findings
                      are reproduced qualitatively by theoretical modeling within
                      the one-step model photoemission formalism. The effect could
                      be understood within the free-electron final state model as
                      an interference due to emission from different atomic sites.
                      The observed effect is a manifestation of time-reversal
                      symmetry breaking of the initial state in the photoemission
                      process, and as such it cannot be eliminated, but only its
                      magnitude influenced, by special experimental geometries.},
