      abstract     = {Recent theoretical calculations predict the presence of
                      Dirac nodal lines with π Berry phase and related
                      topological surface states in elemental alkaline-earth
                      metals. Here we provide experimental and theoretical
                      evidence for the existence of similar nodal lines also in
                      hexagonal close-packed Yb, an element of the lanthanide
                      series, in the limit of zero spin-orbit coupling. These
                      topological properties emerge after taking into account
                      self-energy corrections, which permit one to correctly
                      describe the experimental low-energy electronic structure of
                      Yb. By angle-resolved photoemission spectroscopy we
                      demonstrate the occurrence of topological surface states in
                      Yb which are robust in the presence of the large spin-orbit
                      coupling.},
