      abstract     = {While first-principles calculations with different levels
                      of sophistication predict a topologically trivial Z2 state
                      for bulk bismuth, some photoemission experiments show
                      surface states consistent with the interpretation of bismuth
                      being in a topologically nontrivial Z2 state. We resolve
                      this contradiction between theory and experiment by showing,
                      based on quasiparticle self-consistent GW calculations, that
                      the experimental surface states interpreted as supporting a
                      nontrivial phase are actually consistent with a trivial Z2
                      invariant. We identify this contradiction as the result of a
                      crosstalk effect arising from the extreme penetration depth
                      of the surface states into the bulk of Bi. A film of Bi can
                      be considered bulklike only for thicknesses of about 1000
                      bilayers (≈400 nm) and more.},
