Query: Current-induced H-shaped-skyrmion creation and their dynamics in the
  helical phase   Inevitable for the basic principles of skyrmion racetrack-like applications
is not only their confined motion along one-dimensional channels but also their
controlled creation and annihilation. Helical magnets have been suggested to
naturally confine the motion of skyrmions along the tracks formed by the
helices, which also allow for high-speed skyrmion motion. We propose a protocol
to create topological magnetic structures in a helical background. We
furthermore analyse the stability and current-driven motion of the skyrmions in
a helical background with in-plane uniaxial anisotropy fixing the orientation
of the helices.
