      abstract     = {We present a micromagnetic study on the current-induced
                      domain-wall motion in cylindrical Permalloy nanowires with
                      diameters below 50 nm. The transverse domain walls forming
                      in such thin, round wires are found to differ significantly
                      from those known from flat nanostrips. In particular, we
                      show that these domain walls are zero-mass micromagnetic
                      objects. As a consequence, they display outstanding dynamic
                      properties, most importantly the absence of a breakdown
                      velocity generally known as the Walker limit. Our simulation
                      data are confirmed by an analytic model which provides a
                      detailed physical understanding. We further predict that a
                      particular effect of the current-induced dynamics of these
                      domain walls could be exploited to measure the nonadiabatic
                      spin-transfer torque coefficient.},
