      abstract     = {One-dimensional ballistic transport is demonstrated for a
                      high-mobility InAs nanowire device. Unlike conventional
                      quantum point contacts (QPCs) created in a two-dimensional
                      electron gas, the nanowire QPCs represent one-dimensional
                      constrictions formed inside a quasi-onedimensional
                      conductor. For each QPC, the local subband occupation can be
                      controlled individually between zero and up to six
                      degenerate modes. At large out-of-plane magnetic fields
                      Landau quantization and Zeeman splitting emerge and
                      comprehensive voltage bias spectroscopy is performed.
                      Confinement-induced quenching of the orbital motion gives
                      rise to significantly modified subband-dependent Landé g
                      factors. A pronounced g factor enhancement related to
                      Coulomb exchange interaction is reported. Many-body effects
                      of that kind also manifest in the observation of the
                      0.7·2e2/h conductance anomaly, commonly found in planar
                      devices.},
