      abstract     = {Thin-film sub-5 nm magnetic skyrmions constitute an
                      ultimate scaling alternative for future digital data
                      storage. Skyrmions are robust noncollinear spin textures
                      that can be moved and manipulated by small electrical
                      currents. Here we show here a technique to detect isolated
                      nanoskyrmions with a current perpendicular-to-plane
                      geometry, which has immediate implications for device
                      concepts. We explore the physics behind such a mechanism by
                      studying the atomistic electronic structure of the magnetic
                      quasiparticles. We investigate from first principles how the
                      isolated skyrmion local-density-of-states which tunnels into
                      the vacuum, when compared with the ferromagnetic background,
                      is modified by the site-dependent spin mixing of electronic
                      states with different relative canting angles. Local
                      transport properties are sensitive to this effect, as we
                      report an atomistic conductance anisotropy of up to $~20\%$
                      for magnetic skyrmions in Pd/Fe/Ir(111) thin films. In
                      single skyrmions, engineering this spin-mixing
                      magnetoresistance could possibly be incorporated in future
                      magnetic storage technologies.},
