      abstract     = {Two hundred years ago, Ampère discovered that electric
                      loops in which currents of electrons are generated by a
                      penetrating magnetic field can mutually interact. Here we
                      show that Ampère’s observation can be transferred to the
                      quantum realm of interactions between triangular plaquettes
                      of spins on a lattice, where the electrical currents at the
                      atomic scale are associated with the orbital motion of
                      electrons in response to the non-coplanarity of neighbouring
                      spins playing the role of a magnetic field. The resulting
                      topological orbital moment underlies the relation of the
                      orbital dynamics with the topology of the spin structure. We
                      demonstrate that the interactions of the topological orbital
                      moments with each other and with the spins form a new class
                      of magnetic interactions − topological–chiral
                      interactions − which can dominate over the
                      Dzyaloshinskii–Moriya interaction, thus opening a path for
                      realizing new classes of chiral magnetic materials with
                      three-dimensional magnetization textures such as hopfions.},
