CP² skyrmions and skyrmion crystals in realistic quantum magnets.

ABSTRACT: Magnetic skyrmions are nanoscale topological textures that have been recently observed in different families of quantum magnets. These objects are called CP¹ skyrmions because they are built from dipoles-the target manifold is the 1D complex projective space, CP¹ ≅ S². Here we report the emergence of magnetic CP² skyrmions in a realistic spin-1 model, which includes both dipole and quadrupole moments. Unlike CP¹ skyrmions, CP² skyrmions can also arise as metastable textures of quantum paramagnets, opening a new road to discover emergent topological solitons in non-magnetic materials. The quantum phase diagram of the spin-1 model also includes magnetic field-induced CP² skyrmion crystals that can be detected with r
