      abstract     = {LaNiO3 (LNO) is an intriguing member of the rare-earth
                      nickelates in exhibiting a metal-insulator transition for a
                      critical film thickness of about 4 unit cells [Son et al.,
                      Appl. Phys. Lett. 96, 062114 (2010)]; however, such thin
                      films also show a transition to a metallic state in
                      superlattices with SrTiO3 (STO) [Son et al., Appl. Phys.
                      Lett. 97, 202109 (2010)]. In order to better understand this
                      transition, we have studied a strained LNO/STO superlattice
                      with 10 repeats of [4 unit-cell LNO/3 unit-cell STO] grown
                      on an (LaAlO3)0.3(Sr2AlTaO6)0.7 substrate using soft x-ray
                      standing-wave-excited angle-resolved photoemission
                      (SWARPES), together with soft- and hard- x-ray photoemission
                      measurements of core levels and densities-of-states valence
                      spectra. The experimental results are compared with
                      state-of-the-art density functional theory (DFT)
                      calculations of band structures and densities of states.
                      Using core-level rocking curves and x-ray optical modeling
                      to assess the position of the standing wave, SWARPES
                      measurements are carried out for various incidence angles
                      and used to determine interface-specific changes in
                      momentum-resolved electronic structure. We further show that
                      the momentum-resolved behavior of the Ni 3d eg and t2g
                      states near the Fermi level, as well as those at the bottom
                      of the valence bands, is very similar to recently published
                      SWARPES results for a related La0.7Sr0.3MnO3/SrTiO3
                      superlattice that was studied using the same technique (Gray
                      et al., Europhysics Letters 104, 17004 (2013)), which
                      further validates this experimental approach and our
                      conclusions. Our conclusions are also supported in several
                      ways by comparison to DFT calculations for the parent
                      materials and the superlattice, including layer-resolved
                      density-of-states results.},
